Isset doesn't work after include
<p>I'm having a very very weird issue that I'm unable to see...</p>

<p>I tend to have a "check" in scripts that return things through AJAX so, if you don't give it some key value to POST or GET, it won't work.</p>

<p>So, in my script I have this:</p>

<pre><code>if (isset($_GET['end'])){

do something;
}
else
die ('You are doing it wrong');
</code></pre>

<p>So, having this URL:</p>

<pre><code>calendarEvents.php?start=1314568800&amp;end=1317592800&amp;_=1316538623362
</code></pre>

<p>SHOULD pass the isset. In fact, if I echo the isset result or even the <code>$_GET['end']</code> itself, it ouputs right. Seriously, what's wrong?</p>

<p>Edit: var_dump results</p>

<pre><code>array
  'start' =&gt; string '1314568800' (length=10)
  'end' =&gt; string '1317592800' (length=10)
  '_' =&gt; string '1316538623362' (length=13)
</code></pre>

<p>Edit once again:</p>

<p>I'm including a file here which has another include inside. If I include both files inside the failing file, it works, but if include ones that includes another one it fails. No inception allowed inside PHP...</p>

<p>BTW... Thanks for downvoting. I would like that someone explain me why a valid question with a real problem is downvoted, because don't know how to solve it?</p>
