note 22691 added to function.unlink

Don't know is this a bug or a feature of PHP. When I let the following code runs for like 20 seconds and close browser. Then run another PHP code that writes content to file $page. I either sees no error and that the file $page does exist in the system. Or I see the file $page exist for about 1 second and disappear. But after creating x time of file $page, file $page then will not be deleted. I wonder can it be that PHP is still running the code below which unlink the file or the unlink commands are cached and execute. while(1){ $contents=""; $fp=@fopen("$page", "r"); if($fp){ while(!feof($fp)){ $contents.=@trim(fgets($fp, 128)); } fclose($fp); } if($contents!=""){ @unlink("$page"); } sleep(2); } -- http://www.php.net/manual/en/function.unlink.php http://master.php.net/manage/user-notes.php?action=edit+22691 http://master.php.net/manage/user-notes.php?action=delete+22691 http://master.php.net/manage/user-notes.php?action=reject+22691
