10 Tips to Optimize PHP Programs Laravel 5 Framework

Performance has always been a criticism of the Laravel framework, so tuning Laravel programs is a must-learn skill.

Next I will share some development best practiceswww.itxdl.cn, as well as tuning techniques. If you have other suggestions, please leave a message for discussion.

Here is the simple list:

Configuration information cache artisan config:cache

Route cache artisan route:cache

　Class mapping loading optimization artisan optimize

　 Automatic loading optimization composer dumpautoload

Use Memcached to store session config/session.php

Use professional cache driver config/cache.php

　 Database request optimization

Writing caching logic for the data set

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

Merging front-end resources with Elixir

　1. Configuration Information caching

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 Just 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, and 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 mapping loading optimization

　　 The optimize command merges commonly loaded classes into one file to improve operating efficiency by reducing the loading of files:

　php artisan optimize --force

　 Two files, bootstrap/cache/compiled.php and bootstrap/cache/services.json, will be generated.

　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. The session configuration information is config/session.php , it is recommended to change to professional caching software such as Memcached or Redis:

　 'driver' => 'memcached',

　 6. Use a professional cache driver

It is one of the magic weapons to improve the running efficiency of applications. 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 lazy preloading and preloading when reading data association models;

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

The length here is only related to Laravel. For other content about data optimization, please check other information by yourself.

8. Write caching logic for the data set

Properly use the cache layer operation provided by Laravel to cache the data set taken out from the database, reduce the pressure on the database, and run it in memory The professional caching software on the Internet can also read data much faster than the database.

　 $posts = Cache::remember('index.posts', $minutes = 30, function()

　　, 'tags', 'author', 'seo')->whereHidden(0)->get();

　});

　 remember Even the data association model How convenient it is to cache them together.

　　9. Use just-in-time compiler

　 HHVM and OpCache can easily improve the performance of your application by 50% or higher without making any modifications. 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 .
