Regular Expression

Looking for a little help with regular expressions that I suck at... :(

I have a page where the user can enter a number of email addresses separated by white space, comma, or semi-colon. I found some code on the PHP site to split it by comma and/or whitespace, but I wanted to add semicolon. It looks like so:

$email = preg_split("/[s,]+/", $entry);

So I tried:

$email = preg_split("/[s,;]+/", $entry);

and it seemed to ignore the semicolon. Any help would be appreciated. Thanks.

As in your example, $email will be an array. Try split() which can accept regular expressions as well:

$email = split("[; ,]+", $entry);
