How to improve the performance of PHP framework?

Tips to improve the performance of the PHP framework include: optimizing database queries, using indexes, avoiding wildcards and fuzzy queries; using cache to store frequently read data; creating an object pool to manage object creation and destruction; writing concise and efficient code, using PHP Built-in functions and consider lazy loading.

Tips to improve PHP framework performance

Performance optimization is a key skill that every PHP framework developer must master. By adopting the following techniques, you can significantly improve the responsiveness and overall performance of your framework application:

1. Optimize database queries

• Use indexes to optimize queries to Retrieve data faster.
• Avoid using wildcards (%) and fuzzy queries (LIKE).
• Optimize table structure to reduce join tables and frequent updates.

2. Caching mechanism

• Use cache (such as Memcached or Redis) to store frequently read data, thereby reducing database queries.
• Leverage page caches such as Symfony ESI or Laravel Opcache to serve static pages quickly.

3. Object pool

• Create an object pool to manage object creation and destruction, which can reduce memory allocation and garbage collection.
• For example, in Laravel, the Database facade already uses object pooling to optimize database connections.

4. Code optimization

• Write concise and efficient code to avoid unnecessary calculations or loops.
• Leverage PHP built-in functions to simplify common tasks, such as array_map() and array_reduce().
• Consider using lazy loading and lazy execution to defer calculations until needed.

Practical case: Using object pool in Laravel

In Laravel, you can use the objects of Illuminate\Database\DatabaseManager Pooling to optimize database connections:

use Illuminate\Database\DatabaseManager;
use Illuminate\Container\Container;

$container = new Container();

// 创建一个数据库管理器，并将对象池容量设置为 10
$manager = $container->make(DatabaseManager::class, [
    'options' => [
        'pool' => ['min' => 1, 'max' => 10],
    ],
]);

// 获取一个数据库连接
$connection = $manager->connection('mysql');

// 释放连接回池中
$connection->release();

By using object pools, Laravel can optimize the creation and destruction of database connections, thereby improving application performance.
