	$arr1 = array("dog","cat","bird","fish");
	echo join(" = ",$arr1);

	echo "<br>";

	$arr2[0] = "dog";
	$arr2[1] = "cat";
	$arr2[2] = "bird";
	$arr2[3] = "fish";
	echo join(" = ",$arr2);

	echo "<br>";

	list($arr3[0],$arr3[1],$arr3[2],$arr3[3]) = array("dog","cat","bird","fish");
	echo join(" = ",$arr3);

// This last join will join in the reverse order.

Verified under win2k 4.0.5-dev

This might be the expected behaviour but it is also undesirable. I cant think of a nice way of implmenting a fix due to the fact adding a sort to sort the keys will break lots of peoples scripts. Perhaps just tell the end user to ksort first although I feel arrays with numeric keys should probably join them in order?

This is the expected behaviour and wont be changed anytime soon due to breaking too many scripts if we do. Please use ksort() if you really need to do this.
