It is expected that the $msgs array passed back out of the test() function call would have a pointer pointing to the first item. I confirmed that this works correctly under PHP 4.0.6. 

It doesn't work under 4.2.1 either.

Notice the output of the print_r()

// TEST SCRIPT

$newmsgs = test();
print_r( current( $newmsgs ));
function test()
{
	$msgs[][a] = 10;
	$msgs[][b] = 20;
	$msgs[][c] = 30;
	$msgs[][d] = 40;
	$msgs[][e] = 50;

	while( list( $idx, $msg ) = each( $msgs ) )
	{
		
	}

	return $msgs;
}

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Use reset() or foreach()

Just so you know, I did a lot of looking before I posted this bug. I still cannot find where in the php reference that it describes this behaviour. Do you know where this is documented?

This does work in PHP 4.0.6. I originally wrote the code under 4.0.6 and recently migrated the server to the 4.2.1/2 version.

Any ideas why the switch of behaviors? Was it a bug in php 4.0.6?

Thanks!
