根据公共值重新排序 PHP 数组
我在这里唯一关心的是尺寸。我需要闯入一个新级别的数组并将其添加进去，将它们分组在一起。
我基本上需要将它们全部分组在自己的数组中，这样我就可以循环它们并执行其他操作。
当前数组：
[0] => Array
(
[name] => random name 2
[sizes] => ["XS","S","M","L","XL","XXL"]
)
[1] => Array
(
[name] => random name 1
[sizes] => One Size
)
[2] => Array
(
[name] => random name 3
[sizes] => ["XS","S","M","L","XL","XXL"]
)
通缉：
[0] => Array
(
[0] => Array
(
[name] => random name 1
[sizes] => One Size
)
)
[1] => Array
(
[0] => Array
(
[name] => random name 2
[sizes] => ["XS","S","M","L","XL","XXL"]
)
[1] => Array
(
[name] => random name 3
[sizes] => ["XS","S","M","L","XL","XXL"]
)
)

循环数组并创建一个新数组，暂时将大小作为键。稍后，我们使用 array_values 删除关联键。foreach($arr as $item){ $new[$item['sizes']][] = $item;}$new = array_values($new); // remove associative
