PHP 7.1 - Support for keys in list()

PHP 7.1 – Support for keys in list()

You can now specify keys in list(), or its new shorthand [] syntax. This enables destructuring of arrays with non-integer or non-sequential keys.

<?php
$data = [
    ["id" => 1, "name" => 'Tom'],
    ["id" => 2, "name" => 'Fred'],
];

// list() style
list("id" => $id1, "name" => $name1) = $data[0];

// [] style
["id" => $id1, "name" => $name1] = $data[0];

// list() style
foreach ($data as list("id" => $id, "name" => $name)) {
    // logic here with $id and $name
}

// [] style
foreach ($data as ["id" => $id, "name" => $name]) {
    // logic here with $id and $name
}

<?php

$data = [

["id" => 1, "name" => 'Tom'],

["id" => 2, "name" => 'Fred'],

];

// list() style

list("id" => $id1, "name" => $name1) = $data[0];

// [] style

["id" => $id1, "name" => $name1] = $data[0];

// list() style

foreach ($data as list("id" => $id, "name" => $name)) {

// logic here with $id and $name

}

// [] style

foreach ($data as ["id" => $id, "name" => $name]) {

// logic here with $id and $name

}
