<?php
	$tmp=array(0=>1, "test"=>2);
	list($xx,$yy)=$tmp;
	echo("$xx, $yy");
?>

---Output:start---
1,
---Output:end-----

Variable $yy is empty (only if key name is not integer).
$tmp=array(0=>1, 1=>2);
In this case - it works...

List() can't handle associative arrays. Moved to feature request.

This is now documented as a <note>.

A good feature request is to have list work on associative arrays, which would also mean it won't rely on perfect 0,1,2... order either.

Imho this is a .5 bug and .5 feature request.  Could someone explain why the current behavoir exists?  See also the user notes under list().

Support for associative array destructuring using list() has been added in PHP 7.1, see also: https://wiki.php.net/rfc/list_keys
