Is it safe to use $_SERVER["SCRIPT_NAME"]
<p>I do not want to pass GET or POST variables to a script. I want to use the filename and use it to lookup the product from the phpscript for example:</p>

<p>......./DELL1500.php
......./COMPAQ1213.php</p>

<p>I have three questions:</p>

<ol>
<li><p>Where does PHP get the data from $_SERVER["SCRIPT_NAME"] is it from the server or the clients browser?</p></li>
<li><p>Can anyone think of any security issues of using this?</p></li>
<li><p>Could this in anyway be incompatible with any older browsers. I assume not if its provided by the server?</p></li>
</ol>

<p>Cheers,</p>
