To check email, you can use a function like this:
function validateEmail($email) {
if
(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.(com|net|edu|org|mil))$",$
email)){
return 1;
} else {
return 0;
}
}
To check the others, you'll want to read up on regular expressions. These
will be pretty trivial expressions. Nothing complicated at all...
