How to use reset() and end() Functions In PHP

Using array_shift() and array_pop() Function

PHP provides built-in functions reset() and end() to access the first and last elements of an array.

Example: Here, reset($arr) moves the internal pointer to the first element and returns its value, while end($arr) moves the pointer to the last element and returns its value.

PHP

<?php

// Get First and Last Array Elements
function getFirstAndLast(&$arr) {
    $first = reset($arr);
    $last = end($arr);
    return [$first, $last];
}

// Driver code
$arr = [10, 20, 30, 40, 50];

list($first, $last) = getFirstAndLast($arr);

echo "First Element: $first, Last Element: $last";

?>

Output

First Element: 10, Last Element: 50
