If this functions calls, do something php
<p>I have a function in php which looks like this:</p>

<pre><code>function blabla(){

    // some code

    if(/*function dothis() calls me*/){

        // do this
    }

    return something;
}
</code></pre>

<p>And I have two functions who call <code>blabla()</code>. When the first function calls <code>blabla()</code>, I want that the code outside the if-statement executes. And when the function <code>dothis()</code> calls <code>blabla()</code>, then the code inside the if-statement should be called. How do I build my if-statement? </p>
