depreciate function, how to fix

[MissTa]

Hi,
I have following code and day depreciated, how to replace?

Deprecated: Function session_register()

PHP Code:

function valid_email($address) {
      if (ereg('^[a-zA-Z0-9_\.\-]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$', $address)) return true;
      else return false;
    } 


Deprecated: Function ereg()

PHP Code:

if ($HTTP_POST_VARS) {
        while (list ($key, $val) = each ($HTTP_POST_VARS)) {
            session_register("c$key");
            $_SESSION["c$key"] = $val;
        }
    }

Instead of ereg() use preg_match()

http://at.php.net/manual/en/function.preg-match.php

Simply don't use session_register(). It is enough to do this $_SESSION["c$key"] = $val;

http://at.php.net/session_register

thank you very much

No problem. If you stumble upon another deprecated function just go to

http://www.php.net/manual/en/index.php

and search for the function. You'll see if it is deprecated and an alternative.

This one still not work

PHP Code:

function valid_email($address) {
      if (preg_match('^[a-zA-Z0-9_\.\-]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$', $address)) return true;
      else return false;
    } 


say
Warning: preg_match() [function.preg-match]: No ending delimiter '^' f

God, I never really worked with regex, but I figured out whats wrong. You need to add / one at the beginning and one at the end. Like this

PHP Code:

function valid_email($address) {
      if (preg_match('/^[a-zA-Z0-9_\.\-]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$/', $address)) return true;
      else return false;
    } 


old
'^[a-zA-Z0-9_\.\-]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$'

new
'/^[a-zA-Z0-9_\.\-]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$/'
