note 43454 added to function.flock

your code has a mistake , i think you should change[ $lf = @fopen ($lf, 'x');] to [ $lf = @fopen ($lock, 'x');] and your code has a big problem that if your lockfile is not unlinked for any reason and your function will not work properly. so i think your function is not a good one. ---- Manual Page -- http://www.php.net/manual/en/function.flock.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+43454 Delete -- http://master.php.net/manage/user-notes.php?action=delete+43454&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+43454&report=yes Search -- http://master.php.net/manage/user-notes.php
