PHP Combine two strings
<p>I really have no idea how to do this, or what it would be called. I've searched for the past hour for something like this so:</p>

<p>Is there a way in php to make two strings combine to one. I want to combine strings with the same size together?</p>

<p>So....</p>

<pre><code>$string1 = "apple"
$string2 = "block"
//FUNCTION STUFF HERE
$output = "abplpolcek";
</code></pre>

<p>Thanks in advanced.</p>
