Deprecated: Function eregi() is deprecated contact form

Question

Possible Duplicate:
How can I convert ereg expressions to preg in PHP?

I have a php contact form that I have used on a few different websites. I am trying to implement the same one on a new site, but I am getting the following message:

Deprecated: Function eregi() is deprecated in /home/content/58/10223058/html/contact-1.php on line 36

Here is line 36 from my code:

if(!eregi($string_exp,$name)) {
    $error_message .= 'The Name you entered does not appear to be valid.<br />';
  }

I am sure there is an easy fix for this, but I am very new to PHP and do not know how to go about fixing this!

Any help would be greatly appreciated. Thankyou

So the proper action in your case will be to convert the variable `$string_exp` to a PCRE expression and use `preg_match()` instead of `eregi()`. — Michael Berkowski, Jan 02 '13 at 18:13
eregi is deprecated in PHP 5.3. http://php.net/manual/en/function.eregi.php If your different websites upgrade to PHP 5.3+, you will have the same problem there. — MECU, Jan 02 '13 at 18:14

1) It's just a warning. I'm guessing the code still works, despite the warning. Correct?

2) You can fix it by Googling "Function eregi() is deprecated". For example:

http://takien.com/513/how-to-fix-function-eregi-is-deprecated-in-php-5-3-0.php

// Old
if(!eregi("^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$", $str)) {
    $msg = 'email is not valid';
}
else {
    $valid = true;
}

// New
if(!preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $str)) {
    $msg = 'email is not valid';
}
else {
    $valid = true;
}

Complete PHP on-line documentation is here:

The "man page" for preg_match() is here:

Wow, thats a quick reply, thankyou! – Matt Jacobs Jan 02 '13 at 18:13
yes, the form still works – Matt Jacobs Jan 02 '13 at 18:13
But the warning is very unsightly! – Matt Jacobs Jan 02 '13 at 18:14
Fair enough. To eliminate the warning, simply substitute "preg_match()". Complete PHP documentation is on-line here: http://php.net/manual/en/index.php – paulsm4 Jan 02 '13 at 18:16
> 2) You can fix it by Googling "Function eregi() is deprecated" I just did - that's why I'm here! – thesimm Nov 04 '13 at 09:34

In most cases you can replace

if(!eregi($string_exp,$name)) {

with

if(!preg_match('/'.$string_exp.'/i',$name)) {

but not always - you have to check the pattern ($string_exp).

You could, however, just disable the message by putting this somewhere before the eregi() call:

error_reporting(error_reporting() & ~E_DEPRECATED);
