I don't know of any tutorials for you, but here is a start using regex:
[code]

<?php

if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$",$email))
{
  // $email ok
}

if(preg_match("/^[a-z A-Z]+$/", $name))
{
  // $name contains only letters but allowing spaces
}

if(preg_match("/^[0-9]+$/", $phone))
{
  // $phone contains only numbers
}

?>

[/code]
