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

if you want to get rid of recursive elements:

a=3; $arr->b=&$arr;
//$arr=array('a'=>3, 'b'=>&$arr);
print_r($arr);

$arr_clean=eval('return '.strtr(var_export($arr, true), array('stdClass::__set_state'=>'(object)')).';');
print_r($arr_clean);
?>

output:

stdClass Object ( [a] => 3 [b] => stdClass Object *RECURSION* ) 
stdClass Object ( [a] => 3 [b] => )
