PHP asort() Function

PHP asort() Function


Hello dear readers! welcome back to another section of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP asort() Function.

The PHP asort() function sorts an array such that the array indices maintain their correlation with the array elements which they are associated with. This function is predominantly used when sorting the associative arrays where the actual element order is significant.

Syntax

Following below is the syntax to use this function -

asort( $array [, $sort_flags] );


Parameter Details

Sr.NoParameter & Description
1

array

Required. Specifies an array.

2

sort_flags

Optional. Specifies how to sort the array values. Possible values −

  • SORT_REGULAR − Default. Treat values as they are (don't change types)

  • SORT_NUMERIC − Treat values numerically

  • SORT_STRING − Treat values as strings

  • SORT_LOCALE_STRING − Treat values as strings, based on local settings


Return Value

This built-in function returns TRUE on success and False on failure.

Example

Try out the below example -

<?php
   $fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana" );
   asort($fruits);
   
   print_r($fruits);
?> 

Output

When the above code is executed, it will produce the following result -

Array ( [b] => banana [d] => lemon [a] => orange )
