I have an array:
$a = array(0 => array(1, 2),
1 => array(3, 4),
2 => array(4, 5));
I want to do
foreach ($a as list($q, $r)) { }
i.e. i want the loop to return
$q = 1, $r = 2.
$q = 3, $r = 4.
$q = 5, $r = 6.
However I get
Parse error: parse error, expecting
T_VARIABLE' or '$'' in
[blahblah]
The equivalent would be
foreach ($a as $b) {
list($q, $r) = $b;
}
but that is unnecessarily convoluted
list() is acceptable in function return context so it seems reasonable to have it here also.
(Note: No, I don't mean "foreach ($a as $b => $c)"
I mean "foreach ($a as $b => list ($q, $r))")
