note 102342 added to function.exec

When calling exec() from within an apache php script, make sure to take care of stdout, stderr and stdin (as in the example below). If you forget this and your shell command produces output the sh and apache deamons may never return (they will normally time out after a few minutes). From the calling web page the script may seem to not return any data. If you want to start a php process that continues to run independently from apache (with a different parent pid) use nohub. Example: exec('nohup php process.php > process.out 2> process.err < /dev/null &'); ---- Server IP: 69.147.83.197 Probable Submitter: 83.84.88.174 ---- Manual Page -- http://www.php.net/manual/en/function.exec.php Edit -- https://master.php.net/note/edit/102342 Del: integrated -- https://master.php.net/note/delete/102342/integrated Del: useless -- https://master.php.net/note/delete/102342/useless Del: bad code -- https://master.php.net/note/delete/102342/bad+code Del: spam -- https://master.php.net/note/delete/102342/spam Del: non-english -- https://master.php.net/note/delete/102342/non-english Del: in docs -- https://master.php.net/note/delete/102342/in+docs Del: other reasons-- https://master.php.net/note/delete/102342 Reject -- https://master.php.net/note/reject/102342 Search -- https://master.php.net/manage/user-notes.php
