php INF has value zero
<p>i have a system where the php predefined constant INF var_dumps as 0 (zero).</p>

<pre><code>$inf = INF;
var_dump($inf);
</code></pre>

<p>results:  </p>

<blockquote>
  <p>float(0)</p>
</blockquote>

<p>Is this correct behaviour?
I guess not.</p>

<p>What could have caused that?</p>

<p>This value i would have expected:<br>
