Storing and retrieving cache in Laravel - Mini Project: Build & Apply

Storing and retrieving cache in Laravel

📖 Scenario: You are building a Laravel application that needs to store some data temporarily to speed up repeated requests. Caching helps by saving data so the app does not have to fetch or compute it every time.

🎯 Goal: Learn how to store a value in Laravel cache and then retrieve it later using Laravel's cache facade.

📋 What You'll Learn

Create a cache key and value to store

Set a cache expiration time

Store the value in cache using Laravel's Cache facade

Retrieve the cached value using the same key

💡 Why This Matters

🌍 Real World

Caching is used in web apps to speed up repeated data access and reduce database load.

💼 Career

Understanding Laravel caching is important for backend developers to optimize app performance.

1

Create cache key and value

Create two variables: $cacheKey with the value 'user_count' and $cacheValue with the value 150.

Laravel

# Your code here

Need a hint?

Use simple variable assignment in PHP.

2

Set cache expiration time

Create a variable called $cacheMinutes and set it to 10 to represent cache expiration time in minutes.

Laravel

<?php
$cacheKey = 'user_count';
$cacheValue = 150;
// Set cache expiration time in minutes
# Your code here

Need a hint?

Use a simple integer variable for minutes.

3

Store value in cache

Use Laravel's Cache facade to store $cacheValue in cache with key $cacheKey for $cacheMinutes minutes. Write the line: Cache::put($cacheKey, $cacheValue, $cacheMinutes);

Laravel

<?php
$cacheKey = 'user_count';
$cacheValue = 150;
$cacheMinutes = 10;
// Store value in cache
# Your code here

Need a hint?

Use the put method on the Cache facade with key, value, and minutes.

4

Retrieve value from cache

Retrieve the cached value using Cache::get($cacheKey) and store it in a variable called $cachedUserCount.

Laravel

<?php
use IlluminateSupportFacadesCache;

$cacheKey = 'user_count';
$cacheValue = 150;
$cacheMinutes = 10;
Cache::put($cacheKey, $cacheValue, $cacheMinutes);
// Retrieve cached value
# Your code here

Need a hint?

Use the get method on Cache facade with the cache key.
