Call a function without knowing it's name
<p>I want to create a function in PHP and to call it without knowing the function's name.</p>

<p>Is this possible?</p>

<p>Example:</p>

<pre><code>&lt;?php

     $functionName = "someName";
     $this-&gt;$functionName();
     function someName(){
         echo("Print Message");
     }
?&gt;
</code></pre>
