Weird Session Array Problem

[axman505]

We have the chunk of code at the bottom of the page. It is behaving very strangly under php 4.3.9. Basically, if it is not coded exactly as listed below, it will not work right. The development server is running 5.0.3, and it works fine. However, the live server has 4.3.9. Is there something vastly different with arrays and session variables?

$key = $_REQUEST['quote'];
$quotes = $_SESSION['quotes'][$key];
//unset($_SESSION['quotes'][$key]);
$doc = $file_array[$key];
// handle a new quantity request
if(isset($_REQUEST['qty']) && preg_match('/^\d+$/',$_REQUEST['qty']))
{
if(!(is_array($quotes)))
$quotes = array();

//print $_REQUEST['qty'];
$found = false;
if(count($quotes) > 0)
{
foreach($quotes as $qty)
{
if($qty == $_REQUEST['qty'])
$found = true;
}
}
//print_r($quotes);
if(!$found) {
print "Before";
print_r($quotes);
array_push($quotes, $_REQUEST['qty']);
print "After";
print_r($quotes);
$quoteString = implode(",",$quotes);
$_SESSION['quotes'][$key] = explode(",",$quoteString);
} else {
$quoteString = implode(",",$quotes);
$_SESSION['quotes'][$key] = explode(",",$quoteString);
}
//print_r($quotes);
//sort($quotes);
//print_r($quotes);
//print_r($_SESSION['quotes'][$key]);
//$_SESSION['quotes'][$key] = array();
//$quotes = $_SESSION['quotes'][$key];
print "Session";
print_r($_SESSION['quotes'][$key]);

What do you mean by 'if it is not coded exactly as listed below, it will not work right'?

What is it supposed to do? How does it not work?

Is error reporting set the same on both servers?

Why would this effect the final output:

$quoteString = implode(",",$_SESSION['quotes'][$key]);
$_SESSION['quotes'][$key] = explode(",",$quoteString);

If i do not do that, i get RECURSION errors when doing a print_r on the array.

This only happens on the php 4.3.9 system, its is very odd.
