Optimize PHP function performance with container orchestration technology

Container orchestration technology can improve the performance of PHP functions by optimizing them, such as by adding caching. In the actual case, a Dockerfile was used to create a PHP image with Redis cache and deployed to Kubernetes. By using Redis in PHP functions, data can be fetched from memory, significantly increasing execution speed.

Using container orchestration to optimize PHP function performance: a practical case

Introduction

Container orchestration technology can optimize application performance and improve resource utilization. This article will demonstrate how to use container orchestration technology to optimize the execution speed of PHP functions.

Practical case: Add caching for PHP functions

1. Create a Dockerfile:

FROM php:7.4-fpm
RUN apt-get update && apt-get install -y redis
COPY . /var/www/

• This Dockerfile is created Created an image based on PHP 7.4 and installed Redis cache.

2. Create PHP function:

<?php
function get_cached_data($key) {
    $redis = new Redis();
    $redis->connect('redis', 6379);
    if ($redis->exists($key)) {
        return $redis->get($key);
    } else {
        // 如果缓存中没有数据，从数据库中获取数据
        // 这里省略数据库获取数据的代码
        $redis->set($key, $data);
        return $data;
    }
}

• This function gets and sets data from the Redis cache. If there is no data in the cache, it will be set from obtained from the database.

3. Deploy to Kubernetes:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: php-function-app
  labels:
    app: php-function-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: php-function-app
  template:
    metadata:
      labels:
        app: php-function-app
    spec:
      containers:
      - name: php-function
        image: my-php-function-app:latest
        ports:
        - containerPort: 80

• This Kubernetes deployment will deploy our PHP function container, which contains the Redis cache.

4. Test performance:

Use JMeter or other performance testing tools to benchmark the function and compare the performance difference when caching is enabled and disabled.

Expected results:

After using Redis cache, the execution speed of PHP functions should be significantly improved because the data is obtained from memory instead of from the database Obtained.
