PHP :: Assigning Values To Arrays

Assigning Values Within Href
I'm having a hard time finding information (probably due to how I'm phrasing my searches) on how to assign a variable to an href. The big picture is I have a bunch of photos I'm trying to put on my website. I have an equally large bunch of thumbnails with links, all to the same page (pictures.php) that has a snippet of php (seen below). In my links I am attempting to assign a value to a variable that corresponds with a picture. Code:

Using Quoation Marks When Assigning Values In Php.ini
php.ini which was created on my local w2k during installation has some
no-number and no-logic values assigned using quoation marks whereas the
other with no quoation marks:
upload_tmp_dir = "C:php4uploads"
allow_url_fopen = On
java.class.path = .php_java.jar

And I can not figure out any pattern

Assigning Values Back To Drop Down Box
I have several drop down boxes that I'd like to repopulate with the value
the user selected -- after the form posts by calling itself -- these fields
are blanked out. I am having difficulty getting the drop downs to repopulate
with the values the user's selected. If any of you have implemented this
before, how have you done this and what is the syntax?

[SimpleXML] Assigning Values To Elements Found With XPath
I want to find all elements named "field" in an XML doc and assign a new value to each one. I'd tried something like this:

foreach ($xml->xpath('//field') as &$field)
$field = $value;

But that doesn't work, because (I think) XPath returns a temporary array, not a reference to an actual element. ("PHP Fatal error: Cannot create references to elements of a temporary array expression")

Is there a way to assign values to elements located with XPath, or do I just have to iterate over the whole document?

Assigning Values With Other Values
Say one has an array like such:

array("lang=english", "nomusic=true", "name=Fred", "menu=false");

Is there a function in which I input the array and it makes all the things into variables with the other things as the content like:

$lang="english";
$nomusic="true";
$name="fred";
$menu="false";

Getting Values In An Array Of Arrays
The following is the output of a print_r on an array. The value of
element[0] is itself an array. How do I access the elements in the
second array?

Array ( [0] =Array ( [Vancouver] =Vancouver [Eugene] =Eugene
[Beaverton] =Beaverton ) )

I've tried to set $c[] = $city[0], but this just outputs the same
result.

Inserting Values Into Database Using Arrays
I'm trying to insert the database the answers to a question and to get the user to select the correct answer. PHP Code:

Foreach Loop Contains Arrays In Some Values
I'm looping through the keys and values of a form submission using

foreach($_POST as $key => $value)
echo "$key = $value ";

No problems there. All works as expected. But seveal of the values are
arrays and the echo comes out like:

subjectone = Array
subjecttwo = Array

There could be as many as 9 elements in each array but there may be as
few as one. How can I get those $value that are arrays to echo the
entire array using a foreach loop? I would like to end up with all
values printed in the page whether in an array or not.

How To Slice Multidimensional Arrays By Row Values?
From a DB query, I receive the following result set:

array(array('key1'=>'some val', 'key2'=>'some other val', ..., n),
array('key1'=>'some val', 'key2'=>'some other val', ..., n),
array('key1'=>'some val', 'key2'=>'some other val', ..., n),

Pass Values Of Arrays To A New Page
How do i pass all the values onto another page that I have gathered. If I have a form and place info into the array, how do I pass the value in that array over to a new page.

Passing Checkbox Values Into The Correct Arrays
I've been looking at some code and the net for the past few hours trying to figure out what's wrong and I'm stumped. I have a form - multiple checkboxes (different names) and text fields going into an array. The text fields behave fine - the values from the first entry will populate elements of the first array.

The weird part is that the check boxes will pass the correct values but not always to the correct array element. For example, given two check boxes in a 2 element array, if you check the 1st box in the first element and the 2nd in the second element, on submission, the second element populates the first array element.

I've included a snippet of the code as an example - it's echoing things like crazy because I've been trying to see what's been going on. I hope someone can figure this out for me 'cause I'm completely stuck and am on a deadline. Code:

Storing Values In Arrays Not Their References Or Formulas
We start off by getting the Sire ID from thisDog. Now I want that SireID fixed so that no matter how many times I go back to it. that Sire will be the same dog as he was the very first time. Code:

Comparing Values Of 2 Arrays Combined With Mysql Field Names
I am trying to create an edithistory table that has a text column into which I will put a string that can be read using strtok later to revert changes if necessary. I want to build this function so that it's dynamic enough to be applied to every table so that I don't have to write one for each table that might be updated.

When a row is added to any table (a new entry), it retrieves the next available editid # from the edithistory table and assigns it to that item in the "edits" column for its row in its own table. Every edit made is a new entry in the edithistory table (entryid auto_increment primary key), and the editid is a reference back to the object being edited. Code:

Assigning A Value
Hi all,
I have a form that when submitted goes to the script below:

<?

$date_in = date("Ymd");

$db = mysql_connect('localhost', '', '');

if (!$db)
{
echo "Error: Could not connect to database. Please try again later.";
exit;
}

mysql_select_db("rip");

$query = "insert into securepay(pay_id, name, address, city, postcode, telephone, instructions, ponum, optional_info, amount, merchant_id, date_in)
values('$pay_id','$name','$address','$city','$postcode','$telephone','$instructions','$ponum','$opti onal_info','$amount','$merchant_id','$date_in')";

$result=mysql_query($query);

if($result)
header ("Location: sales_cc.php?pay_id=$pay_id");

echo " <a href="membership.php">Back to Members</a>";
?>

My problem is that when the data is inserted into the database and the header function is executed the $pay_id value on the sales_cc.php page always equals "0". How can i assign the correct value for $pay_id corresponding to the form entry?

I don't know if i have explained this too clearly but if you reply i can answer your questions.

Cheers,
micmac

Assigning The Value Of An Eval() To A String

Assigning Array Elements To Variables
code below prints out the 5 values grabbed by the sql query. what im trying to do is assign these values to variables (dynamically via a loop?) so i can easily insert them in different locations on my page.

Is there a way i can do something like $var0 = array element[0], $var1 = array element[1], etc?

$query = "SELECT price FROM pans";
$result = mysql_query($query,$connection)
or die ("problem");
while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
foreach($line as $col_value) {
echo "$col_value";
}
}

Assigning Variables From Array When Using 'group'
I want to use this query to set variables. The number of variables is consistent, but sometimes the result does not return that same number.. ie one date range may have items from group2,6 and 7, while other date ranges have items in all groups. The query:

Code: "SELECT e_group, sum(amount * quantity) as total FROM expense where e_date between '$arr1_date'"." and '$dep1_date' GROUP BY e_group";

(variables for dates are already defined elswhere in the form) Here is what the table looks like: Code:

Assigning Variables To A Variable / Mail()
What I want to do is send a list of variables through email. I have the mail() working. My problem is assigning the varibles.

$what2mail = $ price1 $price2 $subtotal ;
$to = $email;
mail($to, "Order", $what2mail,"From:me@mycompany.com");

Obviously the $what2mail line is not correct. This will also include some text, i.e. Your order has been received.

Assigning Rows To Unique Variables
Say theres 3 mails in the table.... named "messagetext". Now im trying to work out the best to obtain those 3 mails and put them into 3 unique variables. Which can then be echo'd... would a while loop be best and assigning them ?

Assigning A Time To A Number Range
I have some numbers:

$a = '26';
$b = '25.5';
$c = '24';
$d = '14';
...etc

What I wish to do, is for every .5 = 1 second from the highest number. So, since $a is the highest number, I want it to echo something like this:

0s
+1s (this is $b)
+4s (this is $c)
+24s (this is $d)

if that makes sense?

Assigning Duplicate Integers To An Array Through A Function.
i'm trying to assign duplicate integers to an array within a class object i.e. '$this->items[$productid] = $productid;' this is nested inside a function 'add(&productid) {'. This won't add duplicate items like 17, 17. Any ideas on how to get it to?

Assigning Form Variables In MySQL Query
I have made a website for a local college with a MySQL database of available courses. I want users to be able to search for courses by region.

So far, I have created a drop-down box of options in a html form - and a handle_form page to handle the form. My problem is that I can't link the variable created from the form with the MySQL query.

The relevant php code from the handle_form page is as follows:

$var = ($_POST['region']); //retrieve the variable using superglobals

require_once ('mysql_connect.php'); // Connect to the db.

// Make the query.
$query = 'SELECT * FROM Test WHERE Region ='west'';
$rt = @mysql_query ($query); // Run the query.

while($nt=mysql_fetch_array($rt)){
echo "Branch: $nt[Branch]"; }

I want to replace the 'west' condition with $var so users can see the branches in the selected region - but I don't know how! Not sure if it is simple sytnax I require or to rewrite the query. Have just spent two days trying syntax variations and trawling internet for example scripts but no luck.

Adding Two Variables And Assigning To A Hidden Field
Title says it all. I have a hidden feild and would like to assign it a integer based of two numbers from different recordsets here is my code for what i tried

Assigning A Multi-dimensional Array To & From A Session Variable Loses The Array
I have created a multidimensional array and then assigned that array to a session variable so that I can use it easily on another page. However, when I go to the array later, there's never anything in it. Code:

Adding New Values To An Array That Already Contains Values..
is it possible to append new values to an array that already has values in it??

say, i have my existing array;

existing array;
$array = array([66314] => 66314 , [66315] => 66315) ;

then , when i check my checkbox on my next page, the ids should be appended to the $array:

array that needs to be added to the $array;

$array = array([66316] => 66316,[66317] => 66317,[66318] => 66318);

how should it be done??

What? Assigning A Session Variable Also Assigns The Local Variable?
Alright,
In the following code, I expect the printed result to be:
DEBUG: frank's last name is burns.

Instead, what I get is:
DEBUG: frank's last name is burns.

Here is the code:
$frank = "burns";
$_SESSION['frank'] = "black";
echo "DEBUG: frank's last name is is $frank";

What is coming into play here? I thought of register_globals but I
thought that only dealt with GET, POST, REQUEST, etc.

Assigning "page Of ?", Pdf And RegEx
I am currently well into generating a decent pdf report writer. One thing that I will only know after the file is generated (which I am writing to a text file and then rerouting the user to that file) is how many total pages are in the document. So what I need to be able to do is manipulate either the $buffer from PDF_get_buffer or the text file in such a way as to replace a marker with my final page count.

Here is the bit of code that I thought would do just that:

Assigning "string Value" To GLOBALS
I've noticed assiging a string value to a $GLOBALS variable before a variable of the same name is created does not work, such as the following bit of code: PHP Code:

Arrays Within Arrays, How To Split
I have been stumped on this one and it is probably easier than I think it is, especially since my brain is fried.

This is what my array looks like:
array(7) { ["injuredPerson"]=> string(0) "" ["dates"]=> string(0) "" ["describe"]=> string(0) "" ["location"]=> string(0) "" ["type"]=> array(3) { [0]=> string(8) "abrasion" [1]=> string(10) "amputation" [2]=> string(12) "asphyxiation" } ["part"]=> string(0) "" ["times"]=> string(0) "" }

This is actually an array of information from a form check. I have the error handling check the form and depending on if there is an error or not, the array gets populated with "" or an actual value(s).

I am testing a checkbox area of the form (the name is type, so type can hold an array of values, thats why it currently contains abrasion, amputation, and asphyxiation).

I have had no problem going through the array until I get to the area with an array within the array. Let me give you some code so you can see how I am doing this:

Searching Arrays With Arrays
ive looked through alot of the array search functions and i dont think any of them support arrays as the "needle" to search for.

so say i had a numeric array, $array1 with say 5 elements, 0-4, each element is a single word, lowercase.

say i had another numeric array structured the same way called $array2 with say about 5 elements, 0-4. Is there a function which i could use or does anyone know of an easy way to search every element in $array1 and compair it through each of the elements of $array2? and if a duplicate is found in $array2 have that element be removed or unset? im sure this can be done probably easy with some kind of loop function, but thats my weak point right now in php and im working on it.

Add To Arrays
this is the situation. i am passing variable thru an input form to a function on the same page.
within that function, it will determine if the checkboxes are checked, if it is checked, add that value to one array. if it is not checked, add to a different array.
i do not know the line to add to an array. i am trying array_push but that is not working. array_fill will not work either (do not have php 4.20 installed)

Different Arrays, How To Tell Them Apart?
Is there a function or way to tell the difference between these two types of arrays:

array(1,2,3,4,5,6,7,8,9,0);

array(1=>"one", 2=>"two", 3=>"three", 4=>"four");

The is_array() function does not distinguish between the two as they are both arrays and is_array looks to see if its an array, so back to step 1.

Anyways, is there a function or workaround to find this out??

Arrays
Is there any way that after filling the array in a loop with values that i can go back and start filling in the same array from scratch with a different set of values.

Arrays
is it possible to have an array (or the equivalent) that allows you to say like $text['hi']; or $text['this'];?

PHP 2D Arrays
Please how do we create 2D array and make it global in PHP.

PHP And Arrays?
How can one tell if a PHP array is a simple array or a hashed array
(key/valye). The gettype returns "array", but is there a function
that will tell me the type?

Also, when you have a mixed array, some flat, some hashed, how can you
tell the type of each element?

Using Arrays For Look-ups
Just a quick sanity check...

Sometimes it's useful to use an array as a kind of reverse lookup. For
example, the indexes being productIDs and the value being it's name.

If I do something like this...

$x = array();
$x[1] = 'foo'
$x[345] = 'foo'
$x[12345] = 'foo'

.... PHP is intelligent enough only to allocate 3 data chunks for this right?
As I type this, it seems far more obvious, but if someone could just
confirm :-)

WHILE And Arrays
I appear to have the logic on this one worked out(maybe) but when it goes through the while loop, it only echos the first element of the associated array. Now as a Test I echoed what it should be using as the keys and that works fine. So I don't understand why its failing. With out further ado, heres the problem.. So I have this string in the database, lets say that this string is... PHP Code:

Two Arrays As One
How do I convert the following two arrays into one, and loop through it? Code:
$sections = array("Articles", "Bio", "Disc", "Home", "Photos");
$table_ref = array("articles", "biography", "discography", "homepage", "photos");

for ($i = 0; $i < 5; $i++) {
if ($section == $sections[$i]) {
$result = mysql_query("SELECT * FROM $table_ref$i] WHERE artist_name LIKE '$artist_name' ORDER BY artist_name", $db)
or die("Error =( Unable to connect to database. Please try again later.");
echo create_page($artist_name, $sections[$i], $result);}}

Arrays
when i submit this form, how can i do similar type of processing for all of them,
like the first one i want to add to database, or any other processing maybe not related to database, also .. i can do also for the rest, rather than repeating my codes again and again, i know some sort of array.. but.. how Code:

How To Use Arrays
I want to assign some values from a database into an array. I have two fields, id & name. When I am finding the values from the database, I would like to assign the id to an array and the name into another array. I can do this using the array_push() . How can I then print the array? I tried to just print the variable but it give me 'Array'. Maybe a loop?
PHP Code:

Arrays
I have problems in trying to '++' an array value.
Every time I find a city I add it in the array,
and if I find it many times I increment the value (counter)
of the city. Here's the code:

$address = "http://www.cji.co.il/bw040609.txt";
$address_local = "bw040609.txt";
$lines = file($address_local);

$heading = "Companies covered in this CJI report:";
$heading_line = 0;

$towns = array();

for($i=0; $i<count($lines); $i++) {

$pos = strpos($lines[$i], "Location: ");
if($pos !== false) {
list($loc,$town) = preg_split("/: /", $lines[$i]);
if(in_array($town, $towns)) {
$towns[$town] = 1;
echo "Town added: $town ";

}
else {
$towns[$town]++;
echo "Town added: $town ";
}
}

}

foreach($towns as $key => $value) {
print "$key => $value ";
}

The output is like this:

More About Arrays
Is it possible to read a multi-dimensional array from a file? How would one
represent a multi-dimensional array in a flat file? Is this possible? For
example, I want to have 3 elements in the array, each of which is an array
itself:

Element 1
ARRAY (1-4)
Element 2
ARRAY (1-120)
Element 3
ARRAY (1-1460)

I'd like to store this array in a delimitated flat file - all integers.

3|84|753|2|0|349|5|0| ... and so on

perhaps I need 2 files? other options? (I know... get a database...)

Arrays
I am reading the php manual online and don't understand the way arrays work.
It says arrays take a key, value pair which is fine I guess, but how do I
get an old fashion c style array? Are the keys like the indices?
say I want an array that contains the numbers 0 through 10, what do I make
the keys or does it even matter?

Use Of + With Arrays
In a note on 31-Jul-2002 added to the unshift function the writer
stated that array2=arrray1+array2 was equivalent to
unshift(arrayw,list(array1)). My php seems to take strong objection to
this [Fatal error: Unsupported operand types in
/var/www/html/GEM/etFlush/embryo_newFrozen.php on line 417]. Am I doing
something wrong? Was the original poster on something? Is this a version
problem?
