filterGroup in php

[clonis]

hello,

I would like to list the appointment of the day. I think we should use a filterGroup one filter to select the appointments and other one to filter on the current date.
Can you explain me how to use it ?
I tried something like that :

$gwFG = new FilterGroup();// Instantiate a FilterGroup
$gwFE1 = new FilterEntry('fieldEqual', 'startDate', NULL, 0, 'Today' ); // Instantiate first FilterEntries    
$gwFE2 = new FilterEntry('eq', '@type', NULL , 'Appointment', NULL); // Instantiate second FilterEntries    

$gwFG->element = $gwFE1;// Add the two FilterEntries to the FilterGroup 
$gwFG->op = "and"; // Group the two FilterEntries with an “and”  
$gwFilter = new Filter($gwFG); // Instantiate a Filter

$ir = new getItemsRequest();
$ir->container = $id;
$ir->filter = $gwFilter;
$ires = $gwservice->getItemsRequest($ir); 

Also the function __getLastRequest() doesn't work after using getItemsRequest ()
however I set trace = true

$ gwservice = new GroupwiseService ("groupwisexxx.wsdl"
array (
"location" => "http://groupwisexxx/soap"
"classmap" => $ classmap,
"trace" => TRUE,
"exceptions" => TRUE)
); 

Thank you
