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]
