PHP :: Filling An Array With A Set Of Values

Filling An Array Depending On A Variable
I want to fill an array with numbers depending on a variable.

On the page for holiday booking, the user gives the date of arrival and the date of departure, now i have written code to determine the number of days the user is staying.

Say this is 5, now i want to fill a variable with the numbers 1,2,3,4,5

If the user stays 3 days the variable should be filled with 1,2,3

I came up with this ....

Efficiently & Safely (re)filling Array From $_POST
I'm using a single script to generate a table with <input>s in each row.
I fill the array with initial values, then write it out to the table
and let the user edit the values. Something like:

$myarray = $array(1, 2, 3, ... 100);
echo 'Enter your changes, then click Submit:'
foreach ($array as $i)
echo '<table tags> <input value="'.$i.'" name="index.'$i.'"> <table
tags>'

When the user clicks Submit, I need to pull the values back into the
array so I can re-display & operate on it. The data is in $_POST, which
is associative and contains stuff other than my array. $_POST contains
something like:

Submit=>submit
someVariable=>someValue
anotherVariable=>anotherValue
index1=>1
index2=>99
index3=>93.2
....
index100=>-3

After doing a quick google search, I tried:

for ($i = 0; $i < count($array); $i++)
{
$name = 'index'.$i;
$array[$i] = $_POST["$name"];
}

It runs, but I get nothing out of $_POST - those key values are unset.

Is my only option to inefficiently iterate through $_POST AND $myarray,
and doing the assignment to the proper element when I find the
corresponding name in $_POST's key?

Can I use the $_POST keys as indexes in a loop? If so, is it *safe* to
do that, and what's the syntax? Something vaguely like:

for ($i = 0, $key = index1; $i < 100 && $key < index100; $i++, $key++)
array[$i] = $_POST[$key];

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??

Selecting Array Rows Based On An Array Of Field=>values
Here's the code i have:

$db = array(); //main array
$db['main'] = array(); //table `main`
$db['main'][] = array('id'=>0,
'username'=>'joshfrench','userpass'=>'password','userlevel'=>'admin');
//row
$db['main'][] = array('id'=>1,
'username'=>'bob_smith','userpass'=>'psswrd','userlevel'=>'user');
//row

function trim_value(&$value){
$value = strtolower(trim($value));
}
function fdb_select($fields = "*", $table, $where = false, $limit =
false){
global $db;
$retv = $db[$table];

//LIMIT RESULTS TO FIELDS
if(strrpos($fields, ",") === false){$field=array($fields);}else{$field
= explode(",", $fields);};
array_walk($field, "trim_value");
$all_fields = array_keys($retv[0]);
if($fields == '*'|| is_null($fields)){$field = $all_fields;};
$field = array_uintersect($all_fields, $field, "strcasecmp");
$retvi = array();
foreach($retv as $num =$row){
foreach($row as $fname =$fvalue){
$fname1 = strtolower($fname);
if(in_array($fname1, $field)){
$retvi[$num][$fname]=$fvalue;
};
};
};
//DONE LIMITING TO FIELDS
if($where != false){

//UP TO HERE IT WORKS FINE
//LIMIT TO WHERE CLAUSE
$retvj = array();
foreach($retvi as $num =$row){
//IN THE ROW
foreach($where as $k =$v){
//IF ROW MEETS ALL REQUIREMENTS
if($row[$k] == $v){
$retvj[] = $retvi[$num]; //Keep that row
};
};
};
//DONE LIMITING TO WHERE CLAUSE
};
$retvi = (isset($retvj)) ? $retvj:$retvi;
//SEND A FINAL ASSOCIATIVE ARRAY
return $retvi;
};
print_r(fdb_select("*", "main", array('id'=>"1",
"username"=>"joshfrench")));

the previous code outputs this:

Array
(
[0] =Array
(
[id] =0
[username] =joshfrench
[userpass] =password
[userlevel] =admin
)

[1] =Array
(
[id] =1
[username] =bob_smith
[userpass] =psswrd
[userlevel] =user
)

)

Modifying Values In An Array And Then Putting Them In A New Array
How do i get values out of an array, modify them and then put them back into a new array.
I have tried using a foreach to get the values out and to edit them but i don't know how to get them into a new array. Here's the code:

Array (add More Values To The End)
I have an array. I wan to add more values to the end of the array. how would i go about doing this. my current code does not work. PHP Code:

Comparing Array Values
I'm developing a database that holds information about crew members. There are 7 categories of service types. Crew members can be associated with any number of categories.

I'm working on an update form to add or delete categories for a crew member. I first issued a query to find the member's categories. I issued a second query to list all possible categories. I want to show a checkbox for any possible categories that aren't in the member's individual category list. If the member is in categories 1 and 2, but not in 3 or 4, I want to show a checkbox for categories 3 and 4.

I can get the two category lists to print, but I can't figure out how to compare them.

Here is the code I have for the select statements:

Generates the list of member categories:
$cat_query = "SELECT crew_category.crew_id, crew_category.category_id, category.category_desc
FROM crew_category, category
WHERE crew_category.crew_id = "$crew_id" and crew_category.category_id = category.category_id";

$cat_result = mysql_query($cat_query);

Generates the list of all possible categories:
$all_cat_query = "SELECT category_id
FROM category";

$all_cat_result = mysql_query($all_cat_query);

I'm just developing my programming skills (as I'm sure you can tell), so I apologize for my ignorance! Thanks in advance to anyone who can help!

Adding Values To An Array

Extracting Values From An Array Session!
I am working in a project to add personal info into DB.

For some fields I use session to keep values before putting them into DB. So I wrote a test code to insert phone numbers into a session and at the end put it into DB.

The problem is, I can wirite into the session but don't know how to extract them, as it's an array. My sesison is writen like this:

/tmp/session_file:

n_array|a:5:{i:0;a:1:{i:0;s:6:"VALUE1";}i:1;a:1:{i:0;s:6:"VALUE2";}i:2;a:1:{i:0;s:6:"VALUE3";}i:3;a:1:{i:0;s:6:"VALUE4";}i:4;a:1:{i:0;s:6:"VALUE5";}}

Adding Values Onto An Associative Array...
I'm trying to develop a simple class which through the interface you can add elements to an array. The method I have used to add the elements is setContentFields($name, $field_type), I have used an array counter variable to increment the array index each time. To me this seems like a workaround, and I wondered if there was a more elegant way of doing this.

The class is as follows:

Push Values Into An Array While It's In A Loop
Is it possible to push values into an array while it's in a loop?

Multi-demsion Array Values
I have an array that can be 15 columns by 1 to 5000 rows big. What I need to do is run through a field in the array (manufacturer) to see if there is more than one manufacturer in the array. I dont see a way to do this unless i write a custom function to do it. I am thinking the way would be to pull out manufacture and place them all in an array and then do an array_unique on it and then count the remaining records in the array to determin if there is more than one manufacturer.

Adding Sums Of Array Values
I have two arrays:
('a'=>1,'b'=>3,'c'=>2,'d'=>6)
('a'=>2,'b'=>0,'c'=>4)

I need a very efficient function to add the values together for each element. For instance, the output would be an array:

('a'=>3,'b'=>3,'c'=>6,'d'=>6)

This function could potentially be used in billions of iterations, so it needs to be as efficient as possible.

Declaring Array In A Form And Getting Its Values
I have this form and I want to store some of the values in arrays. I want a 2 dimensional array. If not possible, 1 will be okay. e.g. $myarray[][];

Item 1.1: <INPUT TYPE="TEXT" NAME="myarray[0][0]" VALUE" ">
Item 1.2: <INPUT TYPE="TEXT" NAME="myarray[0][1]" VALUE" ">

Item 2.1: <INPUT TYPE="TEXT" NAME="myarray[1][0]" VALUE" ">
Item 2.2: <INPUT TYPE="TEXT" NAME="myarray[1][1]" VALUE" ">

etc. Is this possible and what is the best way to implement this. The reason I am doing this is because I want to have an SQL statement that goes in a loop manner Code:
