How to use sort() Function In PHP

The sort() function sorts the array in ascending order. After sorting, the largest element will be the last element in the array.

Example: This example shows the use of the above-mentioned approach.

PHP

<?php

// Declare an array
$arr = [10, 20, 30, 40, 50];

// Sort the array
sort($arr);

// The largest element is the 
// last element after sorting
$largest = $arr[count($arr) - 1];

echo "The Largest Element is: " . $largest;

?>

Output

The Largest Element is: 50

Explanation:

$arr is the array containing the elements.
sort($arr) sorts the array in ascending order.
The largest element is the last element of the sorted array, accessed by count($arr) – 1.
