What should I do if the usort () function in PHP is non-stable sorting?

What should I do if the usort () function in PHP is non-stable sorting? Project requirements A group of data is first sorted by parameter 1, and then by parameter 2 if parameter 1 is the same. If usort is a stable sort, use usort to sort the array by parameter 2, and then sort the sorted array by parameter 1. However, after the test, the usort sorting is unstable. what should I do? The code is as follows: 1,'key2'=>1);$a2 = array('key1'=>2,'

, Array_reverse (): Reverse the array5. Shuffle (): Randomly sort the elements of the arraySecond: Sorting of multidimensional arraysUsing functions such as sort (), Ksort (), you can make keywords for one-dimensional arrays, by value, and reverse sort, but these functions cannot be used in multidimensional arrays. You will need to use a user-defined sort function at this point.PHP provides Usort (), Uasort (), Uksort (), functions to sort two-dimensional arrays, which require us to define a sor
