Use either <a href="http://php.net/manual/en/function.substr.php" rel="nofollow"><code>substr()</code></a> or <a href="http://uk3.php.net/manual/en/function.str-replace.php" rel="nofollow"><code>str_replace()</code></a>

<code>substr()</code> is probably the safer option. There's many other ways too.
The <code>swap()</code> you're looking for would be <code>str_replace()</code> (if you just change <code>swap</code> to <code>str_replace</code> should do the trick.

You may want to use <a href="http://www.php.net/manual/en/function.stripos.php" rel="nofollow">stripos()</a> to find the string, then <a href="http://www.php.net/manual/en/function.str-ireplace.php" rel="nofollow">str_ireplace()</a> to replace gmail with googlemail. 

<pre><code>if(stripos($email,'@gmail.com')!== false){
 $email = str_ireplace('gmail.com','googlemail.com',$email);
}
</code></pre>

blocks|key|2671362|text|使用str_replace()：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2671363|$email+=+'example@gmail.com';

Use str_replace():

<pre><code>$email = 'example@gmail.com';
$email = str_replace('@gmail.com','@googlemail.com',$email);
</code></pre>

This will transform <code>example@gmail.com</code> into <code>example@googlemail.com</code>

Normalizing GMail addresses is not as easy as it seems. GMail has the following features to alter an address:

<ul>
<li>Different Domains: gmail, googlemail</li>
<li>Dots are only used for decoration: my.address@gmail.com and myaddress@gmail.com belong to the same mailbox</li>
<li>Random Text can be added using '+' sign: my.addres+sometext@gmail.com

<pre><code>/**
* Normalize a GMail Address.
*
* Example:
* my.name.1+ABC123@gmail.com =&gt; myname1@gmail.com
* my.name@googlemail.com =&gt; myname@gmail.com
*
* @param string $email
* @return string
*/
public function normalize ($email)
{
 foreach (array(
 'gmail.com',
 'googlemail.com'
 ) as $domain) {
 if (substr_count($email, $domain)) {
 $email = preg_replace('/\+.*(@)/i', '\\1', $email); //removes +ABC123
 $email = explode('@', $email);
 $email[0] = str_replace('.', '', $email[0]); //remove dots
 $email = implode('@', $email);
 $email = str_replace('@' . $domain, '@gmail.com', $email); //set default domain
 }
}
return $email;
}
</code></pre></li>
</ul>

I'm creating a register system for my new project. The only problem I have is that @googlemail.com and @gmail.com are recognized as seperate email addresses. Does any one have an idea or some PHP code on how you would change them all from '@googlemail.com' to '@gmail.com'. 

<pre><code>**Some pseudocode to help you**
 $change = '@gmail.com'
 $email = swap($change,'@googlemail.com', $email);
</code></pre>

My programming skills are limited, so don't judge the pseudocode.

Googlemail.com/gmail.com email normalization
