[OpenLayers-Users] WMSGetFeatureInfo popups

[ward]

I really need your help ppl 

I've build a simple map using openlayers and geoserver 
it handles one layer from the geoserver 
I want to create a pop up feature so when i click on a point , a pop up will
appear with point's data 
i follow this example :
http://openlayers.org/dev/examples/getfeatureinfo-popup.html
its source :
view-source:http://openlayers.org/dev/examples/getfeatureinfo-popup.html


then i created a proxy using php : 
<?php 
$url=$_GET["url"]; 
$res = file_get_contents($url); 
echo $res; 
?> 
and put it with the map code in the same folder 

the pop ups appear but they are empty! 
the error msg : element not found 

now, 
1- did i miss something ? 
2- does the proxy right ? i've no experience with php and am not sure about
the syntax .. do i have to replace GET["url"]; with
GET["http://localhost:8080/geoserver/wms"]; ? 
3- do i have to put the code and the proxy in geoserver folder ? 

any sign it would be very helpful
