Filter an dataset with a keyword

i have an list of fonts returned from the googlefontsapi

public function filterFont() {

    $key = $this->request('key');
    $url = "http://ift.tt/29jFcxD";
    $result = json_decode(file_get_contents( $url ));
    $filterfont = array_filter($result, function($obj)
    {
        $data = $obj->font_name == $key;
        $view = view('ajax.fonts', true)->with('data', $data);
        $value=array(

                'view'=>$view
        );
        echo json_encode($value);

    });

}
