根据指定键对关联数组进行排序

安装

composer require lemurro/lib-sorter

使用

$sorter->run(&$array, $key_name, $order_type, $save_keys = true);

• &$array array (必需) - 数据数组（按引用传递）
• $key_name string (必需) - 键名
• $order_type string (必需) - 排序类型 ('asc'|'desc')
• $save_keys boolean (可选) - 保存键（true|false），默认为 true

保留键的排序（默认）

use Lemurro\Lib\Sorter\Sorter;

$sorter = new Sorter();

$array = [
    'z' => [
        'field1' => 'A',
        'field2' => 'orange',
    ],
    'x' => [
        'field1' => 'C',
        'field2' => 'apple',
    ],
    'c' => [
        'field1' => 'B',
        'field2' => 'peach',
    ],
];

$sorter->run($array, 'field1', 'asc');

var_dump($array);
/*
[
    'z' => [
        'field1' => 'A'
        'field2' => 'orange'
    ]
    'c' => [
        'field1' => 'B'
        'field2' => 'peach'
    ]
    'x' => [
        'field1' => 'C'
        'field2' => 'apple'
    ]
]
*/

use Lemurro\Lib\Sorter\Sorter;

$sorter = new Sorter();

$array = [
    'z' => [
        'field1' => 'A',
        'field2' => 'orange',
    ],
    'x' => [
        'field1' => 'C',
        'field2' => 'apple',
    ],
    'c' => [
        'field1' => 'B',
        'field2' => 'peach',
    ],
];

$sorter->run($array, 'field2', 'desc');

var_dump($array);
/*
[
    'x' => [
        'field1' => 'C'
        'field2' => 'apple'
    ]
    'c' => [
        'field1' => 'B'
        'field2' => 'peach'
    ]
    'z' => [
        'field1' => 'A'
        'field2' => 'orange'
    ]
]
*/

不保留键的排序

use Lemurro\Lib\Sorter\Sorter;

$sorter = new Sorter();

$array = [
    'z' => [
        'field1' => 'A',
        'field2' => 'orange',
    ],
    'x' => [
        'field1' => 'C',
        'field2' => 'apple',
    ],
    'c' => [
        'field1' => 'B',
        'field2' => 'peach',
    ],
];

$sorter->run($array, 'field1', 'asc', false);

var_dump($array);
/*
[
    0 => [
        'field1' => 'A'
        'field2' => 'orange'
    ]
    1 => [
        'field1' => 'B'
        'field2' => 'peach'
    ]
    2 => [
        'field1' => 'C'
        'field2' => 'apple'
    ]
]
