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

This function is inherently flawed as by passing the variable to the function the refcount (and other bits) might already be changed. Therefore you shouldn't count on this function too much anyway.
