This article mainly explains "what is the simplest sorting method of php". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "what is the simplest sorting method for php"?

The simplest sorting method: 1, put the three numbers that need to be sorted into an empty array; 2, directly use the built-in array sorting functions sort (), rsort (), asort (), ksort (), arsort (), krsort () to sort the array elements according to certain rules.

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

The simplest way to sort three numbers in php is with the help of the array sort function.

Put the three numbers that need to be sorted into an empty array

Use the built-in array sorting functions sort (), rsort (), asort (), ksort (), arsort (), krsort () to sort array elements according to certain rules.

Example: sort a set of data 10, 23, 5, 12, 84, 16

1. Save it to the array:

$arr = array (10,23,5,12,84,16)

2. sort in ascending order

Sort (): sort array elements in ascending order

Asort (): sorts the array in ascending order according to the key value of the associative array

Ksort (): sorts the array in ascending order according to the key name of the associative array

3. Sort in descending order

Rsort (): sort array elements in descending order

Arsort (): sorts the array in descending order according to the key value of the associative array

Krsort (): sorts the array in descending order according to the key name of the associative array

At this point, I believe you have a deeper understanding of "what is the simplest sorting method of php". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
