[SOLVED] unexpected '&' in foreach

[ratcateme]

I have this script i shifted it to Sourceforge.net and get this error

Parse error: parse error, unexpected '&', expecting T_VARIABLE or '$' in /home/groups/p/ph/phpeasycaptcha/htdocs/Main.class.php on line 61

from this code

<?php
	foreach ($where as &$value) { //line 61
		$value = "`ID` = '{$value}'";
	}
?>

i think i have seen this problem before but a quick google search found no immediate answers.

This & is for?

&$value

[ratcateme]

it means when i change $value it will be changed in the array at the ned.

So you've read up on references?

[ratcateme]

i have read that but i still don't understand what causes the error i have bypassed it but using a for loop but i would really like to know the what caused the problem my testing server is php 5.2.6 and the sourceforge server i moved is php 4.3.10.

You cant pass a variable by reference in a foreach loop, perhaps you mean:

foreach ($where as $key => $value) 
{
    $where[$key] = "`ID` = '{$value}'";
}
