[RESOLVED] using empty() to check arrays?

[sneakyimp]

I was under the (possibly mistaken) impression that if you check an array using empty() it will never be empty, however, this script reports that the array is not empty:

$tmp = array();
if (empty($tmp)) {
  echo 'shiver me timbers!  it *is* empty!';
} else {
  echo 'i told you so! na na na na na na!';
}

I tested this on a php5 server. Is there a difference in how empty works on php4 and php5??

More importantly, is it considered the correct way to see if an array has any elements or not?

If you read the PHP manual on [man]empty[/man], you will find that array() (an empty array) is considered empty.

I had already read that twice in disbelief. I have this vague recollection of checking arrays with empty() only to find that arrays with no elements returned empty() = false.

Is that considered correct usage?

I consider it correct usage for what you want to do.

So be it! Thanks!
