The most commonly used function for array sorting is sort($arr); its function is to sort the array keys in ascending order, and the sorted array key names are no longer the original key names, but the key names reset according to the new array. .
And sometimes we require more complex sorting. For example, if you sort by key name, the ksort($arr); function is used here, which will sort the array according to the key name and maintain the original key-value relationship. The corresponding asort($arr); function is to sort by key value and maintain the original key value relationship
In the same principle, the rsort(); arsort(); krsort(); function is the same as sort(); rsort(); ksort(); except that the sorting is in descending order.
Array operations are a very important foundation of PHP
