[PHP] SPL Countable count() not being called

[Justin Francis]

I have not been able to get count() to be called when I pass my 
Countable class to the count function. I am using PHP 5.1 Release 
Candidate 1. I am not sure if it is a bug, so I am posting here to see 
if anyone can help.

--
class Collection implements Countable
{
 public function count()
 {
   return 200;
 }   
}


$c = new Collection();
echo(count($c));

This code prints 1 out with no errors, when it should print out 200.

Any ideas?

$c = new Collection();
echo(count($c));

Shouldn't this be 

echo Collection-count($c);

or something like that?

Should it not be $c-count() ?

No. By implementing the Countable interface, and implementing the 
count() method, the global count($c) function is supposed to call 
$c-count(). This is so the object can be treated like a countable array 
in the same manner.

Aha, gotcha. Thanks.

I was asleep earlierif $c is not an array 1 will be returned. $c is
one number (200), not an array.

This would be true if the class does not implement the Countable 
interface. It does, however, and so 1 should not be returned, but 
instead, whatever number is returned from the count() method of the 
Collection class. See the SPL documentation at www.php.net/spl for more 
on how this is supposed to work.

SPL is still teething apparently. The docs don't always match the 
current functionality, and, I imagine, it can change from build to 
build. I've recently had some bumpy rides trying to get Recursive 
Iterators working the way I want.


I agree that it should work as you expect it to, and, in my opinion, 
it's a bug. My opinion doesn't count for too much, but there it is.
