PHP :: "Array To String Conversion" Error When Constructing A Multi-dimensional Array

Error In Page When Checking Http_get_vars("myvar") And "myvar" Was Not Passed In URL String
PHP, coming from ASP coding

if (HTTP_GET_VARS['b']==1){
print "Yes";
}else{
print "No";
}

when "b" is not passed via
(http://www.mydomain.com?b=1

an error occurs and the "NO" is printed but an error is printed too.

How can I check for the value of "b" so that no error occurs if b is
not passed??

example

http=www.mydomain.com

$myvar=HTTP_GET_VARS['b']

causes an error because
"b" does not exist (ie. its not passed in the URL string.

$myvar maybe evaluated as NULL or Empty but the error is printed in
the page, anyway.

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:

Finding Elements Of An Array In Another Multi-dimensional Array
So I have 2 arrays:
one contains userids. It may look like:
user_id[0] =12,
user_id[1] =30,
user_id[2] =43

The other is a multi-dimensional array with fields like:
user_info [0] = Array
(
[user_id] =13
[user_flag] =1
[url] =http://www.example.com?index,0
)
user_info[1] =Array
{
Array
(
[user_id] =120
[user_flag] =1
[address] =1234 Main St, Anytown, USA
[url] =http://www.yahoo.com

Turn Array Into Multi-dimensional Array?
How can I take an existing array and turn it into a multi-dimensional array? I want to get a single row out of a MySQL table and have it in an array, but have along side the values the true field (column) length for each of the fields from the table. Here's my stab at it:

$userDetails = mysql_fetch_array($resultID);
$i = 0;
while ($i < mysql_num_fields($resultID))
{
$userDetails[$i][2] = mysql_field_len($resultID, $i);
$i++;
}

And I guess the follow up question (if this is indeed possible) is will this work with a multi-row return from the DB also?

Processing Data From Multiple Multi-line Textareas Into A Multi-dimensional Array
I know that this sounds like something overly complex - because it is.
However, if I can keep the user interface the way it is, my users will
be ultra happy! That is the goal...

In general, this is an inventory receiving piece of an overall larger
web-based ERP system.

What I have is a form in which I have a dynamic number of multline
textareas for inputting (possibly barcode scanning in) many serial
numbers per line item recieved.

For example:
lineitem01 = widget01; qtyReceived = 2;
lineitem02 = widget02; qtyReceived = 3;
lineitem03 = widget03; qtyReceived = 10;

This would display a form that will generate 3 textarea elements (1
per lineitem received). Inside each textarea element will be input the
serial numbers for each of the widgets received per lineitem. i.e. 2
serial numbers will be entered for widget01; 3 for widget02; and 10
for widget03;

So, what I am trying to do is pass this data over, possibly as a multi-
dimensional array to another form ( or possibly $_SERVER['PHP_SELF'] ) to update a MySQL database to store the widget/serial numbers.

Sticking "if" Or Changes Within A MySQL "where" Array?
I'm not exactly sure how to even ask the question, and I know my terminology
is not good as I'm a SQL beginner, but, here goes.

I need to find a way to make an if statement within an array...or, the
"while" portion of a recordset.

The best way I can ask is show what I mean.
http://oscarguy.mechphisto.net/awardbrowse.php
If you go there and select an award (like Best Picture), leave the year
field alone, and select YES and submit, you'll see a lot of results. And I
have HR's dividing each entry.

What I need to do is group all the entries of the same year, or at least
only put HR's between the blocks of years.
So, I'd have all the entries for 2002, an HR, then all for 2001, an HR, etc.

Here at the bottom I'll include my PHP code I'm using so far.
But I have no idea where to even start looking for an answer...if it's even
possible.
If someone can just give me the name of the function or process or
technique, then I can go Web/book searching myself...I just need a direction
of where to go.

Multi Sorting Multi Dimensional Array?
I have been using usort to sort my multi dimensional arrays ...

function cmp($a, $b){
if($a[0] == $b[0]){
return 0;
}
return ($a[0] < $b[0]) ? -1 : 1;
}
usort($searchResults, 'cmp');

Which works fine, but I need to sort by one element in the array, then
another, preserving the previous sort.

lets say the array is as follows:

array[0] = array[0] = foo
[1] = 2
[1] = array[0] = foo
[1] = 0
[2] = array[0] = bar
[1] = 1
[3] = array[0] = bar
[1] = 0
[4] = array[0] = foo
[1] = 1
[5] = array[0] = bar
[1] = 2

Initially, I sort the array in to groups based on array[?][0] using
usort as above so the output is :

foo, 2
foo, 0
foo, 1
bar, 1
bar, 2
bar, 0

Next though, I would like to sort this output by number (array[?][1])
in the groups so that the output is :

foo, 0
foo, 1
foo, 2
bar, 0
bar, 1
bar, 2

Is this possible? I am completely at a loss as to how to do this ...

Array["string"] Or Array[string]
array[string] seems to work well the same way as array["string"] - i know array["string"] is the right way to do it but does it matter ? will it change in future versions of PHP ?

Multi-Dimensional Array
Let's say I have the following multidimensional array:

$foodtypes = array (
"Fruit" => array ("Apple", "Pear"),
"Vegetable" => array ("Lettuce", "Eggplant", "Pepper"),
"Meat" => array ("Beef", "Pork"));

Assuming that $food = 'Eggplant', How do I find what foodtype it belongs to? I know the following works, but I know there must be a better way to do this, like using array_search or array_keys. I can't get anything other the following to work though. Code:

Multi Dimensional Array
I want to go create a table with a textfield where the user can

however, it does not work to save the values coming from the form to
calculate the price.
What's wrong???

Building Multi Dimensional Array
I am trying to build a multi dimensional array from an unsorted array. I have an array made up of the lines in a text file, each line is a comma seperated set of fields. The first two fields are the lines id and it's parents id; eg Line ID, Parent ID, Data

1, 1 , one
2, 2, two
3, 3, three
4, 1, four
5, 4, five
6, 1, six
7, 2, seven

I am trying to build a multi dimensional array so that the final array would look like;

-- one
---- four
------ five
---- six
-- two
---- seven

Sessions And A Multi-dimensional Array
I'm writing a shopping cart w/ Sessions and a multi-dimensional array. I am only storing product id and qty (for right now, but decided on the multi-dimensional array for expansion purposes - storing customer instructions, etc.) I have come up with two paths, but can't decide which is better.

1. storing info based on product id:
...[cart][$prod_id] = array("qty" => $qty)

This, of course would allow for easy product checks: if ([cart][$prod_id]) {...}, but unless I store the $prod_id in the prod_id array as well, I'd be forced to use foreach(array_expression as $key => $value) when displaying the cart (as I also want the product id displayed next to the product name)

2. storing info based on item number:
...[cart][] = array("id" => $prod_id, "qty" => $qty)

This makes for more code when checking if the product is already in the cart (multiple foreach statements), but should allow the cart to be displayed more easily and logical.

Sorting Multi-dimensional Array
I am having trouble getting the sort function for arrays to work correctly on my multi-dimensional array.

array[2][]='age'

array[0][]=Ƌ'
array[1][]='bill'
array[2][]='age'

I then do sort($array[0]) But only array[0][] gets sorted, the names do not follow. Does anyone see any error on my part or have a clue for me to follow to solve this?

Multi-dimensional Array Sorting
I need some help sorting an array, same in structure as:

[key2] => value
[key3] => value

[assoc2] => Array
(
[key1] => value
[key2] => value
[key3] => value
))

What I want to do is sort the array by the value in say the key2 "column". Depending on input, the value to sort by may be key3 or some other key.

I've looked at array_multisort(), but I'm not sure how I can specify what exact column I want to sort by, without affecting the rest.

Multi-dimensional Array Not Working Correctly???
I know this is going to be something totally stupid that I just can't see. I have a two dimensional arrray. The first index is a 0 based incremented int, and the other index is either an 'l' or a 'w'. Look what's happening:

Parsing All Multi-Dimensional Array Combinations
I am trying to build a dynamic table structure with multi-dimensional arrays. The first dimension is being pulled from the databse and can be refferred to as an attribute. The second dimension is also created on the fly by db, and can be reffered to as variations. I have tried using array_walk as well as using a recursive function that allows me to step through each of the various array combinations.

For example I may have 2 attributes; Color & Size. Color has 3 variations (Red, Green, Blue). Size has 4 varitions (Small, Medium Large, X-Large). Basically I am trying to build something like this:

Color Size
Red Small
Red Medium
Red Large
Red X-Large
Green Small
Green Medium
Green Large
Green X-Large
Blue Small
Blue Medium
Blue Large
Blue X-Large

The biggest problem with this, however, is that it needs to be dynamic enough that an attribute (like sleeve length: Short sleeve - Lon sleeve, etc...) can be added without changing the code.

'Parse Error' Problem In "isset" And "empty"
I've been having some problems with a parse error that I can't figure
out (PHP 4.3.11 on Solaris9). Sample code:

<?php
// getting strange parse errors on this
class A {
var $value;
function A() {
$this->value = 1;
}

function getValue() {
return $this->value;
}
}

$a = new A();
if (!empty($a->getValue())) {
echo "success";
}
else {
echo "failure";
}
?>

The result of this is:

Parse error: parse error, unexpected '(', expecting ')' in
/foo/public_html/parse_errors.php on line 15

I also get the same effect with "isset", however, testing with "is_null"
or "is_int" produces the correct ("success"/"failure") result. Any ideas?

Making Mysql Result Into Multi-dimensional Array
My php problem is I want to make the result of 3 tables linked through foreign keys into a 3-dimensional array that reflects their relationship without repetition and without having to call the database more three times.

I know I'm doing a couple of things wrong, one thing for instance is initializing a variable at the end of the loop to remember the previous value s that it does not repeat itself, surely there must be a more elegant way to go about this, but I'm lost and I've been stuck on this all day. Code:

Reading An Array Of Records From MYSQL Then "Save As" Them Back As Copy
Hi all,

Ok here is what I want to do then I will show you what I have. I have some records in a MySQL DB that I want to store in an array and then immediately copy them back where the only thing that would change would be one field - the date. So here is my table:
-------------------------------------
|userName | date | value |
--------------------------------------
| theDano | 200005 | 123 |
--------------------------------------
| theDano | 200005 | 345 |
--------------------------------------
| theDano | 200004 | 678 |
--------------------------------------
| joeUser | 199908 | 897 |
---------------------------------------

So if I am querying for the user "theDano" on a specific date (format yyyymm) in this case 200005 (year 2000 month of May)

Here is my array to query all records to fullfill this request:

if ($update=="future")
{
if ($month!="01")
{
$db = mysql_connect("localhost", "dbuser");
if($db)
{
mysql_select_db("dbName",$db);
$result = mysql_query("SELECT * FROM tableName WHERE userName = '$userName' AND date = '$date' ORDER BY value DESC ",$db);
if ($result)
{
$num=mysql_numrows($result);
$i=0;
while($i < $num)
{
$userName = mysql_result($result,$i,"userName");
$value = mysql_result($result,$i,"value");
echo "<tr>";
echo "<td width=Ê×'>" . $userName . "</td>";
echo "<td width=ï`'><div align='right'>" . $value . "</div></td>";
echo "</tr>";
++$i;
}
}
}
}
}

Now I want to take the array of records queried which was:

| theDano | 200005 | 123 |
--------------------------------------
| theDano | 200005 | 345 |

and copy them to look like this back into the database:

| theDano | 200006 | 123 |
--------------------------------------
| theDano | 200006 | 345 |

so you can see that the only thing changed was increasing the month by one. Would seem simple to most but I am having a tough time wirting the code to read the array and increase each date value by "1".

Thank you in advance for anyone that replies. )

Why Does The Word "Array" Show On A Select Query
I am new to php and MySQL and I'm attempting to run a select query on a
MySQL database which is working fine except prior to displaying the table
with the results from the select query it displays 1 line for each row in
the database containing only the word Array. This is then followed by the
correct results in the constructed table. I am not storing the string
"Array" in my table.

Following is the PHP code for constructing the table from the results
variable.

for ($i = 0; $i < mysql_num_rows($result); $i++)
{
echo "<tr>";
echo $row = mysql_fetch_row($result);
for ($j = 0; $j < mysql_num_fields($result); $j++)
{
echo("<td>" . $row[$j] . "</td>");
}
echo "</tr>";
}

I hope this is enough of the PHP script to solve the problem

Pushing Data Into A Multi-dimensional Array From Mysql Results
First, A result array I'd want to get could look like this:

$chart['chart_data'] = array (
array ( "Region A", 10,12,11,15,20,22,21,25,31,32,),
);

The first is "Region A" and the rest is just int's that I'd pull from the db, so to set it I'd do this:

$chart [ 'chart_data' ][ 0 ][ 0 ] = "Region A";

But the problem is when I want to insert the data in the while loop (like the 10,12,11,15...), I've tried array_push but it's not working, maybe it doesn't work with multi-dimensional arrays? Anyways, here.'s what I tried, the following inside the "while" to loop the mysql results with mysql_fetch_assoc:

while($r=mysql_fetch_assoc($res)) {

$chart [ 'chart_data' ][ 0 ][ 0 ] = array_push($chart['chart_data'][0][0], $r['wght']);
// the above line is where I have problems ^^
}

What I want is on each loop to insert the fetched data inside the array so that it gives what I gave first at the top, but what I've written above doesn't work, it gives me a warning saying "first argument must be an array" which seems to be one, but anyway, anybody know how to do this?
