I want to use php to execute javascript and display the final results to the browser screen.

The objective is to remove the javascript from the source code so that search engine spiders will see the same text that the browser displays.


If you view-source on this page, you will only see the javascript. This is what the spiders see. I want the spiders to see the results displayed in the browser.

Thanks,
Mike

PHP code follows (sorry, tgml corrupted by in code):


<?php
echo'<html>


<script language=&quot;javascript&quot; >
var aqparams = new Array();
var aqThisUri = document.location.href;
function aqExtractQueryParams(qs)
{
var d = 1;
idx = qs.indexOf(\'?\');
if (idx != -1)
{
aqThisUri = qs.substring(0, idx);
query = qs.slice(idx+1);
query = query.replace(/%26/gi, &quot;&&quot;);
defs = query.split(\'&\');
prefix = &quot;?&quot;;
for (i=0;i<defs.length;i++)
{
if (defs != &quot;&quot;)
{
d = defs.split(\'=\');
aqparams[d[0]] = d[1];
if(d[0] != &quot;aqPage&quot;)

One more comment:
Besides giving the spider somthing to relate to the PHP solution also has the advantage that ALL visitors, with or without JavaScript capabilities, have access to your site. There are still people out there that turn JavaScript off or use some intermediary, obsolete brwosing software.

This particular search is run on a remote server (accessquery.com) using .NET protocols. I believe the javascript is required for the search to function.

Does anybody grasp how to pass the required values to the microsoft server using PHP rather than javascript?

I think this requires some clever javascript - u can run your own javascript function on the returned document that returns the actual Document html when the scripts on the page are executed maybe something like &quot;document.body&quot; in javascript may return all the contents withing the body tags - I know createTextRange() works in JScript for IE browswers - u can then extract the needed info from within the tags and submit this thru a form on the same page to your PHP document, all using javascript.

Sorry, there's no way I know of for you to do this w/o using javascript which defeats your automated spider I know.

Looking at the site I can tell you what they did is put in LINK tags to javascript scripts which just contain the TEXT your looking for but even then it's all chopped up with '+' signs to concate them together using javascript. So what you could do is get your PHP page to sniff out the Link tags and then Obtain those script pages that are linked to -> now all you have to do is delete all the instances of '+' and put the words together and then u need to eliminate the <script> tags they put around the text also - a very customized solution.
