Answer 1

I copyed you example and for me it works:

 array(
        36,
        51,
        116,
        171,
        215,
        219,
        229,
        247,
        316,
    ),
    'java' => array(
        14,
        16,
        19,
        24,
        25,
        26,
        29,
        31,
        33,
        34,
        35,
        36,
        37,
        40,
        45,
        49,
        51,
    ),
    'ajax' => array(
        91,
        110,
        113,
        172,
    ),
);

$intersected_array = call_user_func_array('array_intersect',$array);

print_r($intersected_array);

// RESULT: "Array ( ) "

Please copy exactly this code and tell me your output.
