Look what I have accomplished in my script, the problem in my script when " session_destroy();" and " unset($_SESSION['timeout']);" happen it supposed to kill "timeout" then "while loop if(time() >  $st) " will stop. But theses not happing im wondering why. Can you look in my code and see?  

<?php
session_start();
?>


<?php

for( $x=0; $x< 50; $x++ )

{

$st = $_SESSION['timeout'] = time() + 10;

session_destroy();

unset($_SESSION['timeout']);
}

$loop= true;

while($loop)

{

if(time() >  $st)

{

file_put_contents('/tmp/phptest1234.txt', 'test');
$loop=false;
}
}

?>
