此类用于操作和组织数组

安装

使用 composer 安装应用程序包有两种方法

将以下内容添加到 "composer.json" 文件的 require 部分

"mulertech/array-manipulation": "^1.0"

并运行以下命令

php composer.phar update

运行以下命令

php composer.phar require mulertech/array-manipulation "^1.0"

用法

重复值列表

ArrayManipulation::listOfDuplicates([1, 2, 3, 33, 8, 33, 4, 806, 402, 806]);

// [33, 806]

将 "number" 键（或另一个名称）及其数字添加到关联数组中

ArrayManipulation::addNumberKey([0 => ['name' => 'toto'], 1 => ['name' => 'titi']]);

// [0 => ['name' => 'toto', 'number' => 1], 1 => ['name' => 'titi', 'number' => 2]]

通过名称查找差异（可以用于比较旧数组和新数组）

$first =  ['akey' => 'avalue', 'anotherkey' => 'secondvalue',  'thirdkey' => 'oldvalue'];
$second = ['akey' => 'avalue', 'anotherkey' => 'notsamevalue', 'thirdkey' => 'newvalue'];
ArrayManipulation::findDifferencesByName($first, $second);

//['anotherkey' => ['secondvalue', 'notsamevalue'],
   'thirdkey' =>   ['oldvalue', 'newvalue']];

按一列或两列排序（您可以选择列名以及每列的升序或降序）

$array = [
            0 => ['firstcolumn' => 'apple', 'secondcolumn' => 'zorro', 'thirdcolumn' => 'masked man'],
            1 => ['firstcolumn' => 'banana', 'secondcolumn' => 'superman', 'thirdcolumn' => 'masked man'],
            2 => ['firstcolumn' => 'cherry', 'secondcolumn' => 'batman', 'thirdcolumn' => 'masked man'],
            3 => ['firstcolumn' => 'coconut', 'secondcolumn' => 'alibaba', 'thirdcolumn' => 'unmasked man'],
            4 => ['firstcolumn' => 'pineapple', 'secondcolumn' => 'Tom sawyer', 'thirdcolumn' => 'unmasked man']
        ];

ArrayManipulation::orderByColumn($array, 'thirdcolumn', 'desc', 'secondcolumn'); // default order is asc

//Result :
[
            0 => ['firstcolumn' => 'coconut', 'secondcolumn' => 'alibaba', 'thirdcolumn' => 'unmasked man'],
            1 => ['firstcolumn' => 'pineapple', 'secondcolumn' => 'Tom sawyer', 'thirdcolumn' => 'unmasked man'],
            2 => ['firstcolumn' => 'cherry', 'secondcolumn' => 'batman', 'thirdcolumn' => 'masked man'],
            3 => ['firstcolumn' => 'banana', 'secondcolumn' => 'superman', 'thirdcolumn' => 'masked man'],
            4 => ['firstcolumn' => 'apple', 'secondcolumn' => 'zorro', 'thirdcolumn' => 'masked man']
        ];

通过指定键、值以及到最后一个键的键，向数组中添加一个值，

它可以创建最后一个键或将值添加到这个最后一个键中的数组

1. 添加一个键及其值

$array = [
            'subtest1' => [
                'subsubtest1' => 'a value',
                'subsubtest2' => 'b value',
                'subsubtest3' => 'c value'
            ],
            'subtest2' => [
                'subsubsecondtest1' => 'another value a',
                'subsubsecondtest2' => 'another value b',
                'subsubsecondtest3' => 'another value c',
                'subsubsecondtest4' => 'another value d',
            ],
            'subtest3' => [
                'othersub' => [
                    'subsubsub1' => 'value a',
                    'subsubsub2' => 'value b'
                ]
            ]
        ];

ArrayManipulation::addKeyValue($array, 'keytoaddvalue', ['a first value'], 'subtest3', 'othersub');

//Result :
[
            'subtest1' => [
                'subsubtest1' => 'a value',
                'subsubtest2' => 'b value',
                'subsubtest3' => 'c value'
            ],
            'subtest2' => [
                'subsubsecondtest1' => 'another value a',
                'subsubsecondtest2' => 'another value b',
                'subsubsecondtest3' => 'another value c',
                'subsubsecondtest4' => 'another value d',
            ],
            'subtest3' => [
                'othersub' => [
                    'subsubsub1' => 'value a',
                    'subsubsub2' => 'value b',
                    'keytoaddvalue' => ['a first value']
                ]
            ]
        ];

1. 向现有键添加值

$array = [
            'subtest1' => [
                'subsubtest1' => 'a value',
                'subsubtest2' => 'b value',
                'subsubtest3' => 'c value'
            ],
            'subtest2' => [
                'subsubsecondtest1' => 'another value a',
                'subsubsecondtest2' => 'another value b',
                'subsubsecondtest3' => 'another value c',
                'subsubsecondtest4' => 'another value d',
            ],
            'subtest3' => [
                'othersub' => [
                    'subsubsub1' => 'value a',
                    'subsubsub2' => 'value b',
                    'keytoaddvalue' => ['a first value']
                ]
            ]
        ];

ArrayManipulation::addKeyValue($array, 'keytoaddvalue', 'an other value', 'subtest3', 'othersub');

//Result :
[
            'subtest1' => [
                'subsubtest1' => 'a value',
                'subsubtest2' => 'b value',
                'subsubtest3' => 'c value'
            ],
            'subtest2' => [
                'subsubsecondtest1' => 'another value a',
                'subsubsecondtest2' => 'another value b',
                'subsubsecondtest3' => 'another value c',
                'subsubsecondtest4' => 'another value d',
            ],
            'subtest3' => [
                'othersub' => [
                    'subsubsub1' => 'value a',
                    'subsubsub2' => 'value b',
                    'keytoaddvalue' => ['a first value', 'an other value']
                ]
            ]
        ];

通过指定键及其到最后一个键的键，从数组中删除键及其值

$array = [
            'subtest1' => [
                'subsubtest1' => 'a value',
                'subsubtest2' => 'b value',
                'subsubtest3' => 'c value'
            ],
            'subtest2' => [
                'subsubsecondtest1' => 'another value a',
                'subsubsecondtest2' => 'another value b',
                'subsubsecondtest3' => 'another value c',
                'subsubsecondtest4' => 'another value d',
            ],
            'subtest3' => [
                'othersub' => [
                    'subsubsub1' => 'value a',
                    'subsubsub2' => 'value b',
                    'keytoremove' => 'goodbye'
                ]
            ]
        ];

ArrayManipulation::removeKey($array, 'subtest3', 'othersub', 'keytoremove');

//Result :
[
            'subtest1' => [
                'subsubtest1' => 'a value',
                'subsubtest2' => 'b value',
                'subsubtest3' => 'c value'
            ],
            'subtest2' => [
                'subsubsecondtest1' => 'another value a',
                'subsubsecondtest2' => 'another value b',
                'subsubsecondtest3' => 'another value c',
                'subsubsecondtest4' => 'another value d',
            ],
            'subtest3' => [
                'othersub' => [
                    'subsubsub1' => 'value a',
                    'subsubsub2' => 'value b',
                ]
            ]
        ];
