note 97379 added to function.proc-open

Interestingly enough, it seems you actually have to store the return value in order for your streams to exist. You can't throw it away. In other words, this works: <?php $proc=proc_open("echo foo", array( array("pipe","r"), array("pipe","w"), array("pipe","w") ), $pipes); print stream_get_contents($pipes[1]); ?> prints: foo but this doesn't work: <?php proc_open("echo foo", array( array("pipe","r"), array("pipe","w"), array("pipe","w") ), $pipes); print stream_get_contents($pipes[1]); ?> outputs: Warning: stream_get_contents(): <n> is not a valid stream resource in Command line code on line 1 The only difference is that in the second case we don't save the output of proc_open to a variable. ---- Server IP: 69.147.83.197 Probable Submitter: 174.46.204.210 ---- Manual Page -- http://www.php.net/manual/en/function.proc-open.php Edit -- https://master.php.net/note/edit/97379 Del: integrated -- https://master.php.net/note/delete/97379/integrated Del: useless -- https://master.php.net/note/delete/97379/useless Del: bad code -- https://master.php.net/note/delete/97379/bad+code Del: spam -- https://master.php.net/note/delete/97379/spam Del: non-english -- https://master.php.net/note/delete/97379/non-english Del: in docs -- https://master.php.net/note/delete/97379/in+docs Del: other reasons-- https://master.php.net/note/delete/97379 Reject -- https://master.php.net/note/reject/97379 Search -- https://master.php.net/manage/user-notes.php
