How to change cache value in laravel

Laravel is a popular PHP framework that provides convenient caching features to speed up applications. Sometimes we need to change the cache value, this article will introduce how to change the cache value in Laravel.

1. Understanding Laravel Cache

In Laravel, we use the Cache class to operate the cache. Laravel supports a variety of cache drivers, including file cache, database cache, Redis cache, etc.

We can use the get, put, increment and other methods provided by the Cache class to operate cached data. For example:

// 从缓存中获取 name
$name = Cache::get('name');

// 将 name 缓存 1 小时
Cache::put('name', 'Laravel', 60);

// 将 counter 值加 1
Cache::increment('counter');

2. Change the cache value

In Laravel, we can use the put method to change the cache value. For example, cache name for 1 hour, and then change it to Laravel:

// 将 name 缓存 1 小时
Cache::put('name', 'Hello', 60);

// 获取 name 值，输出 Hello
echo Cache::get('name');

// 将 name 更改为 Laravel
Cache::put('name', 'Laravel', 60);

// 获取 name 值，输出 Laravel
echo Cache::get('name');

3. Conditional update cache

Sometimes we need to update the cache based on certain conditions conditions to update cached data. Laravel provides the putIf method to implement conditional update caching.

For example, we need to increase the value of counter by 1, but only update when the value of counter is 5:

// 从缓存中获取 counter 的值
$counter = Cache::get('counter');

if ($counter === 5) {
    // 将 counter 值加 1，更新缓存
    Cache::putIf('counter', $counter + 1, 60);
}

four , Remove the cache

If we need to remove the cache, we can use the forget method:

// 移除 name 缓存
Cache::forget('name');
