Description:
------------
If you loop a file line by line and searching with strpos() it doesn't know if the file has ended, reached EOF. It will contiue untill crash...

Reproduce code:
---------------
//scritp.php
<?php
	$my_position = int;
	$haystack = $file_line[$my_position];
	$position = strpos ( $haystack, $needle );
	while ($position === false){
		$my_position++;
		$haystack = $file_line[$my_position];
		$position = strpos ( $haystack, $needle );
	}
?>

Expected result:
----------------
Nothing to read from or the $haystack has passed the EOF.

Actual result:
--------------
Fatal error: Maximum execution time of 30 seconds exceeded in script.php on line 9
Any line within the while()
during 30sec it can go up to 65.000 - 70.000 lines
