|

|
||
|
|
*
|
||
|
|
* For example:
|
||
|
|
*
|
||
|
|
* ```php
|
||
|
|
* $array = [
|
||
|
|
* ['id' => '123', 'data' => 'abc', 'device' => 'laptop'],
|
||
|
|
* ['id' => '345', 'data' => 'def', 'device' => 'tablet'],
|
||
|
|

|
||
|
|
* ];
|
||
|
|
* $result = ArrayHelper::index($array, 'id');
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The result will be an associative array, where the key is the value of `id` attribute
|
||
|
|
*
|
||
|
|
* ```php
|
||
|
|
* [
|
||
|
|
* '123' => ['id' => '123', 'data' => 'abc', 'device' => 'laptop'],
|
||
|
|
* '345' => ['id' => '345', 'data' => 'hgi', 'device' => 'smartphone']
|
||
|
|
* // The second element of an original array is overwritten by the last element because of the same id
|
||
|
|
* ]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* An anonymous function can be used in the grouping array as well.
|

|
||
|
|
* ```php
|

|
|
* $result = ArrayHelper::index($array, function ($element) {
|

|
||
|
|
* });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Passing `id` as a third argument will group `$array` by `id`:
|
||
|
|
*
|
||
|
|
* ```php
|
||
|
|
* $result = ArrayHelper::index($array, null, 'id');
|

* ```
|

|
*
|
||
|
|
* The result will be a multidimensional array grouped by `id` on the first level, by `device` on the second level
|
||
|
|
* and indexed by `data` on the third level:
|
||
|
|
*
|
||
|
|
* ```php
|
||
|
|
* [
|
||
|
|
* '123' => [
|
||
|
|
* ['id' => '123', 'data' => 'abc', 'device' => 'laptop']
|
||
|
|
* ],
|
||
|
|
* '345' => [ // all elements with this index are present in the result array
|
||
|
|
* ['id' => '345', 'data' => 'def', 'device' => 'tablet'],
|
||
|
|

|
||
|
|

|
||
|
|
* ]
|
||
|
|
* ```
|
||
|
|
*
|
||

|
||
|
|
* }, 'device']);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The result will be a multidimensional array grouped by `id` on the first level, by the `device` on the second one
|

|

|
