[PHP] ereg usage
Could someone please tell me why this code is not working:
ereg ('^[A-H]*([0-9]+)-$', $rank, $matches);
$workshop_ID = $matches[1][2};
where $rank is something like C12-1 and I just need the C12 part.
Many thanks

You're missing the -1 part in your expression:
^ Your string begins
[A-H]* with no or more letters from A to H
([0-9]+)followed by one or more digits (grouped)
-followed by a dash
$ and the end or the string
Your pattern would match C12-, but not C12-1. If you only need the
C12, your pattern should look something like
'^([A-H]*[0-9]+)-'
to return the complete letter/digit sequence at the beginning of the
string, up to (but not including) the dash. Omitting the '$' (string end)
character allows for anything after the dash.

Re: [PHP] ereg usage
The problem is that it's looking for hyphen, - , immediately preceeding the end.
Remove the $.
