💼 Career

Understanding how to manipulate arrays is essential for backend development, scripting, and working with data structures in PHP.

1

Create the initial tasks array

Create an array called tasks with these exact values: 'Buy groceries', 'Clean the house', and 'Pay bills'.

PHP

<?php

// Create the tasks array with three tasks
// Your code here

Need a hint?

Use square brackets [] to create the array and separate the tasks with commas.

2

Add a new task to the array

Use array_push to add the task 'Walk the dog' to the tasks array.

PHP

<?php
$tasks = ['Buy groceries', 'Clean the house', 'Pay bills'];

// Add 'Walk the dog' to the tasks array
// Your code here

Need a hint?

Use array_push with the array name and the new task as arguments.

3

Remove the last task from the array

Use array_pop to remove the last task from the tasks array.

PHP

<?php
$tasks = ['Buy groceries', 'Clean the house', 'Pay bills'];
array_push($tasks, 'Walk the dog');

// Remove the last task from the tasks array
// Your code here

Need a hint?

Call array_pop with the array name to remove the last item.

4

Print the final tasks array

Use print_r to display the final tasks array.

PHP

<?php
$tasks = ['Buy groceries', 'Clean the house', 'Pay bills'];
array_push($tasks, 'Walk the dog');
array_pop($tasks);

// Print the tasks array
// Your code here

Need a hint?

Use print_r($tasks); to show the array content.
