note 56121 added to function.file-exists

If checking for a file newly created by an external program in Windows then file_exists() does not recognize it immediately. Iy seems that a short timeout may be required. <? $file = 'file.tmp'; if ($h = popen("start \"bla\" touch $file", "r")) { pclose($h); // now I would like know if a file was created // note: usleep not supported $start = gettimeofday(); while (!file_exists(trim($file, " '\""))) { $stop = gettimeofday(); if ( 1000000 * ($stop['sec'] - $start['sec']) + $stop['usec'] - $start['usec'] > 500000) break; // wait a moment } if (file_exists($file)) // now should be reliable ?> ---- Manual Page -- http://www.php.net/manual/en/function.file-exists.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56121 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56121&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56121&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56121&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56121&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56121&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56121&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56121&report=yes Search -- http://master.php.net/manage/user-notes.php
