The reverse of the PHP array in an article, "How to sort php arrays," we introduced the sort, asort, and Ksort, which are sorted in ascending order of the array, so if you want to implement the reverse of the arrays? Here's another set of functions we're going to say: Rsort, Arsort, Krsort below we'll introduce this set of functions! rsortrsort-the numeric array in descending order. The Rsort () function reverses the order of the elements of the array by key values. The function is basically the same as Arsort (). The syntax format is as follows: BOOL Rsort (Array & $array [, int $sort _flags = sort_regular]) below we give an example of the Rsort function, the code is as follows: <?phpheader ("Conten T-type

4. PHP Array function sequence krsort-the element key names of the arrays are sorted in descending order, keeping the index relationship
Description:: PHP array function sequence krsort-the element key names of the array are sorted in descending order, keeping the index relationship: Krsort () Definition and usage the Krsort () function reverses the array by key, preserving the original key for the set value. The Second optional parameter contains an additional sort flag. Returns TRUE if successful, otherwise FALSE is returned. The syntax Krsort (array,sorttype) parameter describes the array required. Specifies the array to sort. SortType is optional. Specifies how the values of the array are arranged. Possible values: Sort_regular-Default. In the same place as their original type.

Summary: PHP compares the size of the values in a multidimensional array with the implementation code. If the value is not duplicated, you can use Array_flip () to exchange the key and the value, then Krsort (), and finally Array_flip () swap back, you can compare the size. If you want to intercept an array, you can

9. Summary of data sorting and traversal functions in PHP
Introduction: EC (2); Sorting of arrays in PHP tutorials, there are three kinds of sorting methods, sorted by index, sorted by value (not preserving the original index), sorted by value (preserving the original index). Each of these is divided into ascending, descending, and user-defined order of three functions. They are as follows: Sorted by index: ① ascending ksort () ② descending krsort () ③ user-defined order Uksort () does not retain the original index value sort: ① ascending sort () ② descending rsort () ③ user-defined order usort () keep the original cable
