Black list file extensions

[SysX]

Does any one have any code for black listing particular types of files or data within?

If so could you also tell me where it needs to be placed.

if(preg_match('/(\.jpg|\.gif|\.exe|\.x86|\.bin|\.sh)$/i', $_FILES['userfile']['name'])) {
die("Filetype not allowed.");
}
If you have a UNIX server with the file(1) utility installed, you'll do better to run file on it, and determine whether to keep it or not based on the output.

$op = `file ` . $_FILES['userfile']['tmp_name'];
if(strstr($op, "executable")) {
die("Executable files are not supported.");
}
