PHP COM services, How to use it?

[jayo]

I have a COM Server that create an object with PHP, when from the html input sentence using onchange, goes to a javascript function, as parameter the input value, within this value i want to get from the COM Server an answer. From PHP the object is created with new, as:
$coi = new COM("Coi4ImplP.Coi4");
and I can get from the server the answer as:
$hresult=$coi->Empresa($_POST["empresa"]);
$ruta=$coi->Ruta();
$niveles=$coi->Niveles();
$nombree=$coi->Nombre();
but in the input area from the html page in the from like:
<td><input type="text" size="25" name="cuenta[<? echo($n); ?>]" value="<? echo($cuenta[$n]); ?>" onChange="<? echo rdes($cuenta[$n]);?>"></td>

the function is:
    function  rdes(cta){
var <?php global $coi; $k=$coi->Ruta(); echo('$k='.$k); ?>;
alert($k);
}

I get an error in the page, if I change $k=$coi->Ruta(); to $k=5; it works fine.

Can somebody help me please?

Thank you in advance.

you'd get a better response if this was posted on the [b]php help[/b] forum instead of the javascript forum ;)

either tell a mod to move this or re-post this message.
