10 recommended articles about krsort()

Reverse order of PHP array In an article "How to Sort PHP Array", we introduced sort, asort and ksort. They all sort the array in ascending order. So what if you want to implement the reverse order of the array? Here is another set of functions we are going to talk about: rsort, arsort, krsort. Below we will introduce this set of functions one by one! rsortrsort — Sort a numeric array in descending order. The rsort() function sorts the elements of an array in reverse order by key value. Basically the same function as arsort(). The syntax format is as follows: bool rsort (array &$array [, int $sort_flags = SORT_REGULAR ]) Let’s take an example to explain the rsort function in detail. The specific code is as follows:

Introduction: ec( 2); Sorting of arrays In the PHP tutorial, there are three sorting methods, sorting by index, sorting by value (without retaining the original index), and sorting by value (retaining the original index). Each type is divided into three functions: ascending order, descending order and user-defined order. They are as follows: Sort by index: ① Ascending ksort() ② Descending krsort() ③ User-defined order uksort() Sorting without retaining the original index value: ① ascending sort() ② descending rsort() ③ user-defined order usort() Keep the original code
