PHP 官方针对 7.1 的新提案(RFC)：简化数组的解构方式

This topic created in 3708 days ago, the information mentioned may be changed or developed.

或许 7.1 版本之后，你可以这样：

[$a, $b, $c] = [1, 2, 3];

少打"list"四个字而已

list($a,$b,$c)=[1,2,3];

// This is not allowed:
list([$a, $b], [$c, $d]) = [[1, 2], [3, 4]];

// This is also not allowed:
[list($a, $b), list($c, $d)] = [[1, 2], [3, 4]];

// This, however, is allowed:
[[$a, $b], [$c, $d]] = [[1, 2], [3, 4]];

foreach ($points as ["x" => $x, "y" => $y]) {
var_dump($x, $y);
}
