PHP regular expression for starts w/ a-f or 0-9?

[Anon]

I have a download script that requires me to know the first letter of the file to be downloaded. The filename is stored in a mysql database, but I need to know the first letter of the filename so that I can appropriatly redirect the user because the files will be kind of all over the place. Here's what I'm trying...

case "super nintendo":
if ( eregi ( "^{$[a-m0-9_]{1,} }$", $row->filename ) )
{
$URL = "http://localhost/roms/super_nintendo/" . $row->filename;
}

The $URL is then passed to the redirection HTML of course. As you can see I'm using a switch which determines the category (pulled from the db) of the file. Any help will be much appreciated.

Thanks,
Justin

if (ereg('^{[a-m0-9_]{1,}$',} $row->filename)) {
.
.

should work.

Hi!
If you ONLY need the first letter of the filename, you have to do this:

eregi("^{([a-m0-9_])",} $row->filename, $aux);

and then, in $aux[1] you should have the first letter of the filename.

I¡ve not tested what I'm telling you, but, in theory, it should work. Anyway, let me know if it works or doesn't =)
