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:
//?從緩存中獲取?name
$name?=?Cache::get('name');
//?將?name?緩存?1?小時(shí)
Cache::put('name',?'Laravel',?60);
//?將?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:
//?將?name?緩存?1?小時(shí)
Cache::put('name',?'Hello',?60);
//?獲取?name?值，輸出?Hello
echo?Cache::get('name');
//?將?name?更改為?Laravel
Cache::put('name',?'Laravel',?60);
//?獲取?name?值，輸出?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:
//?從緩存中獲取?counter?的值
$counter?=?Cache::get('counter');
if?($counter?===?5)?{
????//?將?counter?值加?1，更新緩存
????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?緩存
Cache::forget('name');
5. Summary
