A brief introduction to thinkphp template cache settings

With the development of the Internet, today's websites tend to be highly available, high-performance, and highly scalable, and thinkphp, as an excellent PHP framework, just meets these requirements. However, if the template cache is not set appropriately when using thinkphp, it will have a negative impact on performance. In our actual application, it is also very important to pay attention to thinkphp cache settings.

Next, let me briefly introduce thinkphp template cache settings.

1. What is thinkphp template caching

In lay terms, thinkphp template caching is to process the dynamic content in the page, and directly store the processed content Store it in the cache file, and read the processed content from the cache the next time you request to access the page, avoiding frequent trips to the database to obtain the same data, thus greatly improving the performance of the website.

By default, thinkphp has cached templates, but during the actual development process, in order to improve caching efficiency, some settings for the template cache need to be made.

2. How to set up the thinkphp template cache

1. Open the template cache

In thinkphp, you can do it in the following ways Turn on template caching:

 'TMPL_CACHE_ON' => true // 开启模板缓存

After turning on template caching, thinkphp will cache the processed page in a temporary folder. You can read it directly from the file the next time you access it to reduce the impact on the database. Access.

2. Set cache life cycle

In the config.php file, you can set the cache life cycle by modifying the following code:

 'TMPL_CACHE_TIME' => 60 * 60 * 24 // 缓存时间为1天

60 here 60 24 means that the cache life cycle is 1 day. That is to say, the same page will be read from the cache within 1 day. After 1 day, the page will be requested again. The data will be retrieved from the database and the cache file will be regenerated.

3. Set the cache prefix

In thinkphp, you can set the cache prefix, for example:

 'TMPL_CACHE_PREFIX' => 'prefix_' // 设置缓存前缀为 prefix_

In this way, the cache file name will be added prefix to avoid cache files with the same name appearing in different templates.

4. Do not cache the specified template

If some templates do not need to be cached, you can add the following code to the template:

 {nocache}
  这里是不缓存的内容
{/nocache}

Here" "nocache" is a tag defined by thinkphp, which means that the template does not need to be cached.

3. Precautions for thinkphp template caching

1. For pages that are accessed more frequently, it is recommended to enable caching.
2. For pages with more dynamic content, reduce the cache life cycle as much as possible and reduce the memory occupied by the cache.
3. For websites with a large amount of data every day, it is recommended to clean cache files regularly every day to avoid cache files causing server burden.

The above is a brief introduction to thinkphp template cache settings. I hope it can be helpful to everyone and improve the performance of the website.
