Really simple question

[deadonarrival 0]

Really simple question here - I just don't remember exacty how to do it. =P

Anyway I have a string $username and I want to do a quick error check if the username contains a _ or a -

Could anyone give me this line of code please? I thought of using ereg but I'm not too confident in using the function.

Thanks

[code]
if (preg_match('|[-_]|', $username))
  // it contains either a - or a _
else
  // it doesn't contain either
[/code]
