You can do the minimum wait without overloading the CPU thread. ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.173 (proxied: 82.78.175.39) ---- Manual Page -- https://php.net/manual/en/function.sleep.php Edit -- https://main.php.net/note/edit/127652 Del: integrated -- https://main.php.net/note/delete/127652/integrated Del: useless -- https://main.php.net/note/delete/127652/useless Del: bad code -- https://main.php.net/note/delete/127652/bad+code Del: spam -- https://main.php.net/note/delete/127652/spam Del: non-english -- https://main.php.net/note/delete/127652/non-english Del: in docs -- https://main.php.net/note/delete/127652/in+docs Del: other reasons-- https://main.php.net/note/delete/127652 Reject -- https://main.php.net/note/reject/127652 Search -- https://main.php.net/manage/user-notes.php
