apache curl

I am executing successfully the following code using php line mode and it
returns a stream.  However, when running the same code as part of web page,
it appears that get request never gets executed.  Why?  any help is
appreciated.

        $apikey = '73f1ad78334ea3e8dedfb8f568d8537f';
        $username='auser';
        $dealid=1;
        $apiurl='http://apserveri02:8080/rest/default/qadm/v1/';


        $ch = curl_init();

        $headr = array();
        $headr[] = 'Accept: application/json';
        $headr[] = 'Content-Type: application/json';
        $headr[] = 'Authorization '.$apikey.':1';

        curl_setopt($ch, CURLOPT_HTTPHEADER,$headr);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_URL,
$apiurl."Rsnapshot?filter=dealid=$dealid");
        $content = curl_exec($ch);
        echo $content;
        exit;
