<p>I'm a new to php and I'm using <a href="http://www.dclassifieds.eu" rel="nofollow">this</a> php script for my website. Its requirements are in <a href="http://www.dclassifieds.eu/Requirements-pid6.html" rel="nofollow">here</a><br>
As it says, I have to define <code>$_SERVER variable</code>. 
But I have no idea what it is, what its value should be and where to put it.</p>

<p>Any help please?</p>
