note 109534 added to function.unregister-tick-function

It's not so clear, but, at least as of PHP 5.3.13, you cannot use this inside of the handler itself as it will throw an error: <?php declare(ticks=2); function tick_handler() { unregister_tick_function('tick_handler'); } register_tick_function('tick_handler'); set_time_limit(0); usleep(500000); ?> results in: warning: unregister_tick_function(): Unable to delete tick function executed at the moment in [filename] So if you want to unregister it must be done outside of the handler. ---- Server IP: 69.147.83.197 Probable Submitter: 74.141.242.55 ---- Manual Page -- http://www.php.net/manual/en/function.unregister-tick-function.php Edit -- https://master.php.net/note/edit/109534 Del: integrated -- https://master.php.net/note/delete/109534/integrated Del: useless -- https://master.php.net/note/delete/109534/useless Del: bad code -- https://master.php.net/note/delete/109534/bad+code Del: spam -- https://master.php.net/note/delete/109534/spam Del: non-english -- https://master.php.net/note/delete/109534/non-english Del: in docs -- https://master.php.net/note/delete/109534/in+docs Del: other reasons-- https://master.php.net/note/delete/109534 Reject -- https://master.php.net/note/reject/109534 Search -- https://master.php.net/manage/user-notes.php
