validation

[rupturedtoad]

Im writing some code that checks a password. One of the things i want to do is ensure that the string contains at least one letter and at least one number - ie ajk4ti would be accepted but gjknbx and 3847584 would be rejected.

I could obviously do this with loops going through the string, but there must be a more elegant solution that eludes me - can anyone help? Thanks.

if(eregi("[a-z]{1}", $password) && eregi("[0-9]{1}", $password)) {
   // valid
}
else {
   // invalid
}

Thanks LordShryku, that's just what I needed.
