Change array to a string with commas ordered asc in php
<p>I have an array:</p>

<pre><code>$array = array(
"peter",
"john",
"maria",
"bob"); 
</code></pre>

<p>And now I somehow need to change the array to a string (ordered asc) like:</p>

<pre><code>$string_with_commas = "bob, john, maria, peter";
</code></pre>
