Optimization techniques for programs in the PHP laravel5 framework (recommended)

The performance of the Laravel framework has never been very good. Therefore, when learning the PHP laravel framework, you must master the optimization of the Laravel program. Next, I will share some of the best development solutions and optimization techniques.

Here is a simple list:

Configuration information cache artisan config:cache

Route cache artisan route:cache

Class map loading optimization artisan optimize

Autoload optimization composer dumpautoload

Use Memcached to store session config/session.php

Use professional cache driver config/cache.php

Database request optimization

Write caching logic for the data set

Use a just-in-time compiler (JIT), such as: HHVM, OpCache

Front-end resource merging with Elixir

1. Configuration information cache

Use the following Artisan built-in command to merge all the configuration information in the config folder into one file to reduce the number of files loaded at runtime:

php artisan config:cache

The above command will generate the file bootstrap/cache/config.php. You can use the following command to cancel the configuration information cache:

php artisan config:clear

What this command does is delete the bootstrap/cache/config.php file.

Note: The configuration information cache will not be automatically reloaded with updates. Therefore, it is recommended to turn off the configuration information cache during development. It is generally used in production environments and can be used with the Envoy task runner.

2. Route cache

Route cache can effectively improve the registration efficiency of the router. The effect is more obvious in large applications. You can use the following command:

php artisan route:cache

The above command will generate the bootstrap/cache/routes.php file. It should be noted that the route cache does not support routing anonymous function writing logic.

You can use the following command to clear the route cache:

php artisan route:clear

What this command does is delete the bootstrap/cache/routes.php file.

Note: The route cache will not be automatically reloaded with updates. Therefore, it is recommended to turn off the route cache during development. It is generally used in production environments and can be used with the Envoy task runner.

3. Class map loading optimization

#optimize command merges commonly loaded classes into one file to improve operating efficiency by reducing file loading:

php artisan optimize --force

will generate two files, bootstrap/cache/compiled.php and bootstrap/cache/services.json.

You can add classes to be merged by modifying the config/compile.php file.

In the production environment, the parameter --force does not need to be specified, and the file will be automatically generated.

To clear class map loading optimization, run the following command:

php artisan clear-compiled

This command will delete the two files generated by optimize above.

Note: This command must be run after php artisan config:cache, because the optimize command generates files based on configuration information (such as the providers array of the config/app.php file).

4. Automatic loading optimization

This command is not only for Laravel programs, but also applies to all programs built using composer. This command will convert PSR-0 and PSR-4 into a class mapping table to improve class loading speed.

composer dumpautoload -o

Note: This operation has already been done in the php artisan optimize --force command.

5. Use Memcached to store sessions

Every Laravel request will generate a session. Modifying the session storage method can effectively improve program efficiency and session configuration information. It is config/session.php. It is recommended to change it to professional caching software such as Memcached or Redis:

'driver' => 'memcached',

6. Use a professional cache driver

"Cache" is the best way to improve the application One of the magic weapons for program running efficiency, the default cache driver is file cache. It is recommended to switch to a professional cache system, such as Redis or Memcached. It is not recommended to use database cache.

'default' => 'redis',

7. Database request optimization

Use delayed preloading and Preloading;

Use Laravel Debugbar or Clockwork to pay attention to the total number of database requests for each page;

The space here only writes about Laravel-related content. For other content about data optimization, please refer to it yourself Check out other information.

8. Write caching logic for the data set

Reasonably use the cache layer operation provided by Laravel to cache the data set taken out from the database, reducing the database The professional caching software running on the memory can also read data much faster than the database.

$posts = Cache::remember('index.posts', $minutes = 30, function()
{
return Post::with('comments', 'tags', 'author', 'seo')->whereHidden(0)->get();
});

remember Even the data association model is cached, how convenient it is.

9. Use the just-in-time compiler

HHVM and OpCache can easily make your application 50% faster without making any modifications. % or higher performance, PHPhub did an experiment before. For details, please see: Using OpCache to improve PHP 5.5 program performance.

10. Front-end resource merging

As an optimization standard, a page should only load one CSS and one JS file, and the file must be able to easily go to CDN, and the file name needs to change with modification.
