Allow all characters in a PHP “explode” function
I have a piece of PHP code that gets a list of allowed extensions from the WordPress Database and only allows files uploaded that are those file extensions. What I would like to do is make the code allow ALL extensions but NOT allow only a couple of file extensions (executables like exe, shells, binaries, etc.)
Here is the code:
$allwd_ext = get_option( ‘ma_allowedExtension’ );
$allowedExts = explode(“,”,$allwd_ext);
$extension = end(explode(“.”, $_FILES[$f_u][“name”]))`;
Any ideas appritiated
