check for symbols in a string?

[Mark]

for example, how would i check to see if an @ symbol is included in a registration form when submited?

Well, if you want an actual email validation checker, that's a bit of a different problem.
However, to just check if there is an @:
if (eregi("@",$email)) {
// Yep, there's an @ sign.
}

Hi mark, i use this to validate my emails:

if(!eregi("^[0-9a-z_-]+(\\.[0-9a-z_-])*@[0-9a-z-]+\\.[a-z]{2,6}(\\.[a-z]{2,6})*$", $email)) {

// Invalid address
} else {

// Valid
}
