How to use array_shift() and array_pop() Function In PHP

We can use array_shift() and array_pop() to retrieve and remove the first and last elements of an array, respectively.

Example: The array_shift($arr) removes and returns the first element, and array_pop($arr) removes and returns the last element. Note that this method modifies the original array by removing these elements.

PHP

<?php

// Get First and Last Array Elements
function getFirstAndLast(&$arr) {
    $first = array_shift($arr);
    $last = array_pop($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
