Purpose

This class is intended to change keys order in associative arrays with one line of code.

Installation

composer require germanovs/php-keys-mover

Properties

string $message Contains information about last operation. You can read this to find what excatly went wrong, if any methods returned false.

Methods

move(array &$array, string|integer $key, string|integer $where): bool

• Moves $key in $where position inside $array.
• $key and $where and can be string as key or integer as index.
• Modifies source array directly.
• Returns true on success and false on failure.

Usage

$keyMover = new KeysMover\KeysMover();
$array = [
    'one' => 1,
    'two' => 2,
    'three' => 3
];

$keyMover->move($array, 'one', 'two');
/*
result:
[
    'two' => 2,
    'one' => 1,
    'three' => 3
]
*/

$keyMover->move($array, 'two', 2);
/*
result:
[
    'one' => 1,
    'three' => 3,
    'two' => 2
]
*/

Future plans

These methods will be available in future versions

• shift(array &$array, string|integer $key, integer $shift): bool Moves $key by $shift positions Ex: $keysMover->shift($array, 'three', -2);

• moveAfter(array &$array, string|integer $key, string|integer $target): bool Puts $key after $target Ex: $keysMover->moveAfter($array, 'three', 'one');

• moveBefore(array &$array, string|integer $key, string|integer $target): bool Puts $key before $target Ex: $keysMover->moveAfter($array, 'three', 'two');

• rearrange(array &$array, array $order): bool Rearranges keys in $array, using $order as pattern Ex: $keysMover->rearrange($array, ['two', 'three', 'one']);

Methods move() and shift() will get bool $swap = false argument. This will alow to move replaced key to initial position of moved key.
