note 57932 added to function.pcntl-wait

Below is a simple example of forking some children and timing the total duration (useful for stress tests). <?php $isParent = true; $children = array(); $start = microtime( true); /* Fork you! * (Sorry, I had to) */ $ceiling = $CONCURRENCY - 1; for ( $i = 0; (( $i < $ceiling) && ( $isParent)); $i++) { $pid = pcntl_fork(); if ( $pid === 0) { $isParent = false; } elseif ( $pid != -1) { $children[] = $pid; } } /* Process body */ echo "Do stuff here\n"; /* Cleanup */ if ( $isParent) { $status = null; while ( count( $children)) { pcntl_wait( $status); array_pop( $children); } echo "Completed in " . ( microtime( true) - $start) . " seconds.\n"; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.pcntl-wait.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57932 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57932&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57932&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57932&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57932&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57932&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57932&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57932&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57932&report=yes Search -- http://master.php.net/manage/user-notes.php
