note 94016 added to function.usleep

VERY VERY IMPORTANT!!! Under Windows systems, if you do not set the time limit of the execution of your script to 0 ("set_time_limit(0);"), the php executable will eat as much as 50% CPU power when using sleep or usleep functions. This is an extremely annoying behavior. It took me a lot of time to figure it out. It may have something to do with the fact that the usleep and sleep are "supervised" by the time limit set by set_time_limit() which defaults to 30 seconds; --that's just my assumption. I may be wrong, I am only human ;) It's quite simple, but the set_time_limit() function is poorly documented at this level. <?php set_time_limit(0); // Remove the time limit for command-line usage; $counter = 0; // Some simple counter; while ($counter < 100) { // Do nothing for 100*100 miliseconds (10 seconds); $counter++; usleep(100000); // Sleep for 100 miliseconds; } Good luck! ---- Server IP: 69.147.83.197 Probable Submitter: 89.137.116.105 ---- Manual Page -- http://www.php.net/manual/en/function.usleep.php Edit -- https://master.php.net/note/edit/94016 Del: integrated -- https://master.php.net/note/delete/94016/integrated Del: useless -- https://master.php.net/note/delete/94016/useless Del: bad code -- https://master.php.net/note/delete/94016/bad+code Del: spam -- https://master.php.net/note/delete/94016/spam Del: non-english -- https://master.php.net/note/delete/94016/non-english Del: in docs -- https://master.php.net/note/delete/94016/in+docs Del: other reasons-- https://master.php.net/note/delete/94016 Reject -- https://master.php.net/note/reject/94016 Search -- https://master.php.net/manage/user-notes.php
