Syntax

sort( $array [, $sort_flags] );

Definition and Usage

This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.

This function assigns new keys for the elements in array. It will remove any existing keys you may have assigned, rather than just reordering the keys.

Parameters

Parameter Description
array Required. Specifies an array.
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

Returns TRUE on success or FALSE on failure.

Example

Try out following example −

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

This will produce the following result −

Array
(
   [0] => banana
   [1] => lemon
   [2] => orange
)
