Description:
------------
I am seeing a bug in PHP 5.3 where the WHILE LOOP is not meeting all of the conditions. The same code was working great in PHP 5.2 but broke after a PHP upgrade. I reviewed the PHP 5.3 change-log and nothing is mentioned for changes in WHILE LOOP conditions.


Test script:
---------------
<?php

function cutTextPer($string, $setlength) {
    $rlength = $setlength;
    if($rlength<strlen($string)){
	while (($string{$rlength} != '.') && ($rlength > 0)) {
	    $rlength--;
	}
	if ($rlength== 0) {
		return substr($string, 0, $setlength);
	} else {
		return substr($string, 0, $rlength).'.';
	}
    }else {
	return $string;
    }
}

$mstr = 'ProNeticas has released a visual rapid database design tool. This allows you to generate online programs in rapid time, without any programming.';

print cutTextPer( (String)$mstr, 52);

?>

[OUTPUT IN PHP 5.2]
ProNeticas has released a visual rapid database design tool.

[OUTPUT IN PHP 5.3]
ProNeticas has released a visual rapid database de


Expected result:
----------------
ProNeticas has released a visual rapid database design tool.

Actual result:
--------------
ProNeticas has released a visual rapid database de
