PHP javascript or ASP

[rayzun]

I found this script to show information about visitors to my website and related information if they clicked on any ads from Adsense.

Except my pages are PHP based. Can this script be converted or basically should I forget about it and look for something else?

<script language="JavaScript">
var iFr;
function AdSenseLog()
{
var theAd=""+ escape(window.status.substring(6)) ;
var format=queryString('format',iFr.src);
var channel=queryString('channel',iFr.src);
var bug = new Image();
var thetitle='<%=Request.Servervariables("SCRIPT_NAME")%>';
bug.src = '/yourcapturepage.aspx?ref=' + document.referrer + '&url=' +theAd +'&title=' + thetitle+ '&format=' + format +'&channel='+channel ;
}

function queryString(item, source)
{
var itemLoc=source.indexOf(item);
var newSrc=source.substring(itemLoc);
var endLoc=newSrc.indexOf("&");
var lstSrc=newSrc.substring(0,endLoc);
var itm=lstSrc.substring(item.length+1);
return itm;
}

var elements;
elements = document.getElementsByTagName("iframe");

for (var i = 0; i < elements.length; i++)
{
if(elements.src.indexOf('googlesyndication.com') > -1)
{
elements.attachEvent("onfocus",AdSenseLog)
iFr=elements;
}
}

</script>

this looks like a ASP server code that emits client side java script. you can emit the same client side script from a php page, yes. just replace Request.Servervariables("SCRIPT_NAME") with the corresponding $_REQUEST variable(s) and change syntax for string concatenation.

To elaborate on konsu's answer, it looks like it's all client-side Javascript except for the bit that reads

<%=Request.Servervariables("SCRIPT_NAME")%>

, and so that's the only bit that needs translating into PHP.

And, depending on what yourcapturepage.aspx is supposed to be, chances are you'd be wanting to change that to yourcapturepage.php when you translate it (this is one reason why the W3C recommends not useing technology-dependent URLs: why should the client have to care what language the server is using to generate pages?)
