The sort Function

The sort function sorts an array in ascending order by its elements. The function modifies the array itself.

Syntax

sort(array &$array, int $flags = SORT_REGULAR): bool

Example

Let's sort an array in ascending order by its elements:

<?php $arr = [1, 3, 2, 5, 4]; sort($arr); var_dump($arr); ?>

The code execution result:

[1, 2, 3, 4, 5]
