PHP asort() Function

PHP asort() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP asort() Function.

The built-in PHP asort() function is used for sorting an array in such a way that the array indices maintain their correlation with array elements associated with them. This built-in function is mainly used when sorting the associative arrays where the actual order of the element is significant.


Following below is the syntax to use this function -

asort( $array [, $sort_flags] );

Parameter Details

Sr.NoParameter & Description


Required. Specifies an array.



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 function returns TRUE on success and FALSE on failure.


Try out the below example -

   $fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana" );


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

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