note 99568 added to function.passthru

Thanks to "ignacio paz posse" below, I was able to solve a problem where I didn't want anything echoed back from the shell. on my system: exec, passthru, and exec all sent standard output back to the browser -- which is a problem in AJAX apps. For systems running PHP 5.2 and older, you can use the following code to get the MIME type, e.g. in this case .mp2/.mp3 files: ob_start(); passthru("file -bi -- ".escapeshellarg($sourceFile), $finfo); ob_get_contents(); ob_end_clean(); if ($finfo=='audio/mpeg') { } ---- Server IP: 117.104.162.229 Probable Submitter: 203.59.102.142 (proxied: 203.59.102.142) ---- Manual Page -- http://www.php.net/manual/en/function.passthru.php Edit -- https://master.php.net/note/edit/99568 Del: integrated -- https://master.php.net/note/delete/99568/integrated Del: useless -- https://master.php.net/note/delete/99568/useless Del: bad code -- https://master.php.net/note/delete/99568/bad+code Del: spam -- https://master.php.net/note/delete/99568/spam Del: non-english -- https://master.php.net/note/delete/99568/non-english Del: in docs -- https://master.php.net/note/delete/99568/in+docs Del: other reasons-- https://master.php.net/note/delete/99568 Reject -- https://master.php.net/note/reject/99568 Search -- https://master.php.net/manage/user-notes.php
