From: "Robert P. J. Day" on 8 Mar 2010 10:57 hi, i'm interested in the most comprehensive way to determine the content type of a stream of bytes that's been uploaded to a PHP script? assuming that the bytes are uploaded simply via a POST parameter, i can see that there are a couple ways to do it: * getimagesize() * FileInfo i've been doing some testing this morning and a few video formats handed to FileInfo come back as "application/octet-stream" which isn't particularly informative. and i want to support as many different formats of image, audio and video as possible. so ... what's the best way? oh, by the way, when i used fileinfo, i didn't bother handing over a magic file. i'm starting to think that would make a difference. and is there a noticeable advantage to upgrading to PHP 5.3 since the server (centos 5.4) is currently running only PHP 5.1.6. thanks. rday -- ======================================================================== Robert P.
