Description:
------------
Currently, I filter out the content of the function debug_zval_dump() to get the reference count of a variable. It would be better if there was a function in PHP to get this information straight away, without the need for parsing output.

Reproduce code:
---------------
// My current code:
ob_start();
debug_zval_dump($var);
$output = ob_get_contents();
ob_end_clean();
$pos = strpos($output, "refcount(");
if ($pos === false) return 0;
$refcount = intval(substr($output, $pos + 9));

// Feature request:
$refcount = refcount($var);

Expected result:
----------------
The internal refcount of a variable

Actual result:
--------------
N/A
