note 40569 added to function.move-uploaded-file

An extension only does not really tell you what type of file it really is. I can easily rename a .jpg file to a .zip file and make the server think it is a ZIP file with webmaster kobrasrealm's code. A better way is to use the Linux utility "file" to determine the file type. Although I'm aware that some users might use Windows on their webservers, I thought it's worth mentioning the utility here. Using the backtick operators and preg_matches on the output, you can easily determine the file type safely, and fix the extension when necessary. ---- Manual Page -- http://www.php.net/manual/en/function.move-uploaded-file.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+40569 Delete -- http://master.php.net/manage/user-notes.php?action=delete+40569&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+40569&report=yes Search -- http://master.php.net/manage/user-notes.php
