How to find variables dynamically created, but not with extract?
<p>I'm working on an old site, written by somebody else, and they've done something equivalent to <code>extract($_POST)</code> somewhere in there code. But they didn't use the function extract.</p>

<p>The application was originally designed for PHP3 (yes, old), then it was ported to PHP4, and now I'm porting it to PHP5. </p>

<p>Does anyone know of what function it could be? Or, any way of finding it out? I've tried using PHPStorm's 'GoTo -> Declaration' but that wasn't it....</p>

<p>I've scanned the documents for the variable and there is no other reference to it, so its being generated by a function equivalent to extract.</p>
