How do I call a function using a function name generated from a string variable
<p>In the process of automating some code, I am looking to call upon a function based on what a string is.  </p>

<p>For example, I have a variable <code>$somevar</code> which is set to the string "This".  Now I want to run a function <code>doThis();</code></p>

<p>So, I was hoping I could write <code>do.$somevar($var,$var2)</code> .  I want it to run <code>doThis($var1,$var2)</code>.</p>

<p>Is this possible?</p>
