Description:
------------
If you call empty() on an array with 0 elements, then it will return true.
However, if you call empty() on a Countable object with a count of 0, it
returns
false.
This could catch out people who are implementing objects with Countable as
array
stand-ins.
Test script:
---------------
<?php
class Test implements Countable
{
public $count = 0;
public function count ()
{
return intval (abs ($this -> count));
}
}
$test = new Test ();
var_dump (empty ($test));
var_dump (count ($test));
$test -> count = 10;
var_dump (empty ($test));
var_dump (count ($test));
Expected result:
----------------
bool(true)
int(0)
bool(false)
int(10)
Actual result:
--------------
bool(false)
int(0)
bool(false)
int(10)
