使用 list() 解构数组

使用 list() 快速将变量值列表分配到数组中。另见 compact()

// Assigns to $a, $b and $c the values of their respective array elements in           $array with keys numbered from zero
list($a, $b, $c) = $array;

使用 PHP 7.1（目前处于测试阶段），你将能够使用短列表语法 ：

// Assigns to $a, $b and $c the values of their respective array elements in $array with keys numbered from zero
[$a, $b, $c] = $array;

// Assigns to $a, $b and $c the values of the array elements in $array with the keys "a", "b" and "c", respectively
["a" => $a, "b" => $b, "c" => $c] = $array;
