I have sugar crm instance and i was trying to get some data from it using soap service.

Below is the code which i am using for it.

When i run the same code , sometimes it is returning correct data, sometimes it not.

Can any one tell me what the problem is??

    include "nusoap.php";

    $client = new soapclient( http://asdf.net/test/urbancrm_2009_06_22/soap.php );
    // Login to SugarCRM
    $auth_array = array(
         user_auth  => array(
                 user_name  =>  ****** ,
                 password  =>  ******* 
            ),
        );
    $response = $client->call( login , $auth_array);
    if (!$response[ error ][ number ]){
        // Successfully logged in
        $session_id = $response[ id ];

        //$response = $client->call( get_entry_list ,array( session =>$session_id ,  module_name => Users ,  query =>  ,  order_by =>  , offset =>  , select_fields =>array( id , user_name )));
        $response = $client->call( get_entry_list ,array( session =>$session_id ,  module_name => itf_Apartments , "query"=>"itf_apartments_cstm.neighborhood_c= Loop ",  order_by =>  , offset =>  , select_fields =>array( name , studio , convertible , one_bedroom , one_bedroom_plus_den , two_bedroom , two_bedroom_plus_den , penthouse , photo_c , building_type_c , neighborhood_c )));
        //$response = $client->call( get_entry_list ,array( session =>$session_id ,  module_name => itf_Apartments ,  query => itf_apartments_cstm.urbanlux_id_c="1" ,  order_by =>  , offset =>  , select_fields =>array( name , studio , convertible , one_bedroom , one_bedroom_plus_den , two_bedroom , two_bedroom_plus_den , penthouse ,)));  
        //store id and user name as a key value pair in array
        //echo "---";
        print_r($response);


    } else {
        echo "else";
        print_r($response);
    }

?>
