function getting redeclared

Hi, I have a problem where I am getting the following error, and I was wondering if anyone has seen this one before and can help me out. "Fatal error: Cannot redeclare isvalidphonenumber() (previously declared in /home/bluekomo/public_html//classes/Registrant.class:360) in /home/bluekomo/public_html//classes/Registrant.class on line 360" I have a script, "registration.php", which calls require_once on the Registrant.class file mentioned in the above error message. The Registrant::setPhone() method is called more than once. Since it is called more than once, the function "isValidPhoneNumber()" defined within setPhone() is defined more than once, which I suspect is the source of the problem. Does PHP not allow you to define a function within a function and then call the enclosing function more than once? Here is the relevant section of code: 354 /** 355 * sets the phone property 356 */ 357 function setPhone($phone) {

358     // TODO: determine if these formats are acceptable
359     // TODO: account for extensions (separate form field?)
360     function isValidPhoneNumber($num) {
361         $valid = false;
362         if (preg_match('!\d{9,9}!', $num)) {
363             $valid = true;
364         }
365         if (preg_match('!\(?\d\d\d\)?-?\s*\d\d\d-?\s*\d\d\d\d!',
366             $num)) {

367

368             $valid = true;
369         }

370

371         return $valid;
372     }

373

374     if (isValidPhoneNumber($phone)) {
375         $this->phone = $phone;
376     }

377 } I am using PHP 4.3.0 on a RedHat machine with Apache 1.3.x. Thanks for your help, it's been a while since I've used PHP! Erik -- Erik Price email: erikprice@mac.com jabber: erikprice@jabber.org
