Why Background Processing Improves Performance in Laravel

📋 What You'll Learn

💡 Why This Matters

🌍 Real World

Background processing is used in web apps to keep the user interface fast by handling slow tasks like sending emails or processing images behind the scenes.

💼 Career

Understanding queues and background jobs is essential for Laravel developers to build scalable and responsive applications.

Progress0 / 4 steps

Create the initial data structure

Create an array called $newUsers with these exact email addresses: 'alice@example.com', 'bob@example.com', and 'carol@example.com'.

Laravel

# Create the array $newUsers with the specified emails
# Your code here

Need a hint?

Use a PHP array with the exact variable name $newUsers and the emails as strings.

Add a configuration variable for background processing

Create a boolean variable called $useQueue and set it to true to enable background processing.

Laravel

$newUsers = ['alice@example.com', 'bob@example.com', 'carol@example.com'];
# Create the boolean variable $useQueue and set it to true
# Your code here

Need a hint?

Use the exact variable name $useQueue and assign it the boolean true.

Dispatch email jobs using Laravel queues

Write a foreach loop using $email as the iterator variable to go through $newUsers. Inside the loop, if $useQueue is true, dispatch a job called SendWelcomeEmail with $email as the argument. Otherwise, call a function sendEmailNow($email).

Laravel

$newUsers = ['alice@example.com', 'bob@example.com', 'carol@example.com'];
$useQueue = true;
# Loop through $newUsers and dispatch SendWelcomeEmail job if $useQueue is true
# Otherwise, call sendEmailNow($email)
# Your code here

Need a hint?

Use the exact variable names and function calls as specified. The dispatch function sends the job to the queue.

Complete the SendWelcomeEmail job class

Define a class called SendWelcomeEmail with a constructor that takes $email and stores it in a property. Add a method called handle that calls sendEmailNow with the stored $email.

Laravel

$newUsers = ['alice@example.com', 'bob@example.com', 'carol@example.com'];
$useQueue = true;

foreach ($newUsers as $email) {
    if ($useQueue) {
        dispatch(new SendWelcomeEmail($email));
    } else {
        sendEmailNow($email);
    }
}

// Define the SendWelcomeEmail job class below
// Your code here

Need a hint?

Make sure the class and method names match exactly. The handle method is what Laravel calls to process the job.
