Retrieving data from 2D Array's off of Form Submits

[justride]

The following code was working, not sure the version of PHP that I was using, but I know it worked on 4. Rrecently my host upgraded to PHP Version 5.2.13, and all of the code is broken.

I have an HTML Form Submit.

My HTML Form POST the following variable "requirements" as 2D array data fine, which I can see in the HTTP POST via HTTPAnalyzer.

Here is the data from the POST

requirements[0][] = 1
requirements[0][] = 2
requirements[0][] = 3
                                                
requirements[1][] = 4
requirements[1][] = 5
requirements[1][] = 6

In PHP I am doing the following which no longer seems to work.

$requirements[][] = $_POST['requirements[][]'];
$_SESSION['requirements'] = $requirements;

...

for($i=0;$i<=$requirementArrayCount;$i++)
{
    $requirementsDelimited = '';
    for($x=$i;$x<$i+1;$x++)
    {
        for($j=0;$j<count($requirements[$x]);$j++)
        {
	    $requirementsDelimited = $requirementsDelimited.";".trim($requirements[$x][$j]);
	}
    }
    // do something with requirementsDelimited
}

Usually, requirementsDelimted would be "1;2;3" and "4;5;6"

Now what is happening is only 1 iteration is happening for each loop, and requirements[0] is an array of length 1 with no value at requirements[0][0]

Thoughts? Workarounds?

I'm not saying the code is pretty, but this has been in place for 5 years and stopped working just recently.

Thanks,
Chris

There is no obvious reason why your code will have broken between php 4 and php5.

session_start();
$_SESSION['requirements'] = $_POST['requirements'];
$requirementsDelimited = array();
foreach($_POST['requirements'] as $val):
 $requirementsDelimited[] = implode (';', $val);
endforeach;
print_r($requirementsDelimited);

I will try your much cleaner implementation this evening.

Thanks
