This article mainly introduces six ways of sorting arrays in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

Six sorting methods for arrays:

1. sort() sorts the array in ascending order

$string=array("M","B","A"); sort($string); print_r($string);123

2. rsort() sorts the array in descending order

$string=array("M","A","C"); sort($string); print_r($string);123

3. asort() sorts the array in ascending order according to the value of the array

$person_age=array("john"=>"28","piter"=>"25","davies"=>"30"); asort($person_age); print_r($person_age);123

4. ksort() - sorts the array in ascending order according to the key of the array

$person_age=array("john"=>"28","piter"=>"25","davies"=>"30"); ksort($person_age); print_r($person_age);123

5. arsort() sorts the array in descending order according to the value of the array

$person_age=array("john"=>"28","piter"=>"25","davies"=>"30"); arsort($person_age); print_r($person_age);123
