add arguments to function's name in php?
<p>actually I wish to create a function which combine all similar functions with similar function name. For example,</p>

<pre><code>&lt;?php
//this function carry the function name I wish to create. For example:function try
a("try");


function a($arg)
{
  //I wish to create function with the name carried by $arg
  //but function $arg won't work
}
?&gt;
</code></pre>

<p>Anyone can guide me regarding such function?</p>
