405 - HTTP verb used to access this page is not allowed

Hello I’m using II7
I’ve downloaded the packge for php and unzipped.
The code is pretty simple:
mygrid.toPDF(“/iCubeWeb/codebase/grid-pdf-php/generate.php”) ;

but when execute the navigator give me the next error:

405 - HTTP verb used to access this page is not allowed.
The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access.

Example:
myToolbar.attachEvent(“onClick”, function(id){
switch (id) {
case “save”:
testajax();
break;
case “pdf”:
/*mygrid.toPDF(“http://dhtmlxgrid.appspot.com/export/pdf”) ; */
mygrid.toPDF(“/iCubeWeb/codebase/grid-pdf-php/generate.php”) ;
break;
case “xls”:
/*mygrid.toExcel(“http://dhtmlxgrid.appspot.com/export/excel”) ; */
mygrid.toExcel(“/iCubeWeb/codebase/grid-excel-php/generate.php”) ;
break;
}

					} ); 

Could you help me please?

Thank you in advanced.

It’s necessary to download and install the package for PHP in the server?

windows.php.net/download/

?
