Cache drivers (file, Redis, Memcached) in Laravel - Mini Project: Build & Apply

Cache Drivers Setup in Laravel

📖 Scenario: You are building a Laravel application that needs to store temporary data efficiently. Laravel supports multiple cache drivers like file, Redis, and Memcached. You will configure and use these cache drivers step-by-step.

🎯 Goal: Set up Laravel cache drivers by creating the cache configuration, selecting a cache driver, and writing code to store and retrieve cached data using the chosen driver.

📋 What You'll Learn

Create a cache configuration array with file, Redis, and Memcached drivers

Set a variable to select the default cache driver

Write code to store a value in the cache using the selected driver

Write code to retrieve the cached value and complete the cache usage

💡 Why This Matters

🌍 Real World

Caching is used in web applications to speed up response times by storing frequently accessed data temporarily. Laravel supports multiple cache drivers to fit different needs and environments.

💼 Career

Understanding cache drivers and how to configure them is important for backend developers working with Laravel to optimize application performance and scalability.

1

Create cache configuration array

Create a PHP array called cacheConfig with keys 'file', 'redis', and 'memcached'. Each key should have a nested array with a 'driver' key set to the same string as the key name.

Laravel

# Your code here

Need a hint?

Think of cacheConfig as a list of cache driver settings. Each driver has a name and a driver type.

2

Set default cache driver

Add a variable called defaultDriver and set it to the string 'redis' to select Redis as the default cache driver.

Laravel

 ['driver' => 'file'],
    'redis' => ['driver' => 'redis'],
    'memcached' => ['driver' => 'memcached'],
];

# Your code here

Need a hint?

Set defaultDriver to the exact string 'redis' to pick Redis as the cache driver.

3

Store a value in cache using the selected driver

Write code to create a variable cacheStore that simulates storing the string 'Laravel Cache' with the key 'welcome_message' using the defaultDriver. Use an array to represent the cache storage with the driver as the first key and the cache key as the second key.

Laravel

 ['driver' => 'file'],
    'redis' => ['driver' => 'redis'],
    'memcached' => ['driver' => 'memcached'],
];

$defaultDriver = 'redis';

# Your code here

Need a hint?

Use $cacheStore[$defaultDriver]['welcome_message'] = 'Laravel Cache'; style to store the value.

4

Retrieve the cached value and complete cache usage

Add a variable cachedValue that retrieves the value stored under 'welcome_message' from cacheStore using defaultDriver. Then add a comment // Cache setup complete to mark the end.

Laravel

 ['driver' => 'file'],
    'redis' => ['driver' => 'redis'],
    'memcached' => ['driver' => 'memcached'],
];

$defaultDriver = 'redis';

$cacheStore = [
    $defaultDriver => [
        'welcome_message' => 'Laravel Cache'
    ]
];

# Your code here

Need a hint?

Retrieve the cached value by accessing $cacheStore[$defaultDriver]['welcome_message'].
