PHP: check if object/array is a reference

Question

Sorry to ask, its late and I can\'t figure a way to do it... anyone can help?

$users = array(
    array(
        \"name\" => \"John\",
        \"age\"   =         


        

Answer 1

function var_reference_count(&$xVal) {
    $ao = is_array($xVal)||is_object($xVal);

    if($ao) { $temp= $xVal;    $xVal=array();    }

    ob_start();        
     debug_zval_dump(&$xVal);
    $dump = ob_get_clean();

    if($ao) $xVal=$temp;

    preg_match('/refcount\((\d*)\)/',$dump,$matches);
    return $matches[1] - 3;
}

This works with HUDGE objects and arrays.
