Ok well you validate an email address using the following function:

Code: [ Select ]
function isValidEmail($email) {
    return eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email);
}
  1. function isValidEmail($email) {
  2.     return eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email);
  3. }

(Returns boolean e.g true/false)

Good luck with the rest :)

The POSIX Regex "ereg" functions have been deprecated (officially as of PHP version 5.3.0), you should use preg_match with the "i" flag. Example:

PHP Code: [ Select ]
<?php
function isValidEmail($email) {
return preg_match("#^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$#i", $email);
}
?>
  1. <?php
  2. function isValidEmail($email) {
  3. return preg_match("#^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$#i", $email);
  4. }
  5. ?>


If you don't know much about CAPTCHA I recommend using: http://recaptcha.net/

You can easily get someones IP with $_SERVER['REMOTE_ADDR'], I wouldn't rely on the IP layer though, so escape it.

Date & Time are easily aquired via the php Date/Time Functions.

I have a feeling your chances of someone re-writing your script for free are slim. Attempt to do it on your own and if you have more specific problems I'm sure someone will help you.
There's no place like 127.0.0.1, badass part is now it's ::1
