note 95889 added to book.exec

I'm looking for a way to check if a process is running. I cant find a good php method. I am now using this function in my code. Not working in Windows <?php function is_running($PID) { if (is_numeric($PID)) return exec("ps -p $PID >> /dev/null && echo \"1\" || echo \"0\""); return false; } ?> ---- Server IP: 83.137.20.135 Probable Submitter: 82.94.107.45 ---- Manual Page -- http://www.php.net/manual/en/book.exec.php Edit -- https://master.php.net/note/edit/95889 Del: integrated -- https://master.php.net/note/delete/95889/integrated Del: useless -- https://master.php.net/note/delete/95889/useless Del: bad code -- https://master.php.net/note/delete/95889/bad+code Del: spam -- https://master.php.net/note/delete/95889/spam Del: non-english -- https://master.php.net/note/delete/95889/non-english Del: in docs -- https://master.php.net/note/delete/95889/in+docs Del: other reasons-- https://master.php.net/note/delete/95889 Reject -- https://master.php.net/note/reject/95889 Search -- https://master.php.net/manage/user-notes.php
