PHP e-commerce system development guide performance optimization

In PHP e-commerce systems, performance optimization is crucial, and performance can be improved through the following techniques: Using caching, such as PSR-16 compatible adapters, to reduce database query and page load times. Optimize database queries, such as using indexes, conditional indexes, and restrictive clauses to improve query efficiency. Reduce unnecessary HTTP requests such as merging images, using CSS Sprites, and loading content via Ajax. Enable GZIP compression to reduce HTTP response size. After implementing these optimizations, e-commerce websites can significantly improve page loading speed and reduce server resource consumption, thereby optimizing customer experience.

PHP E-commerce System Development Guide: Performance Optimization

In the field of e-commerce, website performance is crucial. Customers expect websites to load quickly and be responsive, otherwise they are likely to turn to a competitor. In this article, we’ll explore various PHP performance optimization techniques to help you create a fast, efficient e-commerce system.

Caching

Caching is a powerful technique that can be used to store frequently requested data to reduce database query and page load times. On an ecommerce website, you can cache content such as product lists, shopping cart items, and recent views.

Example:

use Psr\SimpleCache\CacheInterface;
use Symfony\Component\Cache\Adapter\FilesystemAdapter;

$cache = new FilesystemAdapter();

$cachedProducts = $cache->get('products');
if ($cachedProducts === null) {
    // 从数据库获取产品
    $cachedProducts = getProductsFromDatabase();
    $cache->set('products', $cachedProducts, 3600);
}

Optimize database query

Slow database query will seriously affect website performance. Be sure to use indexes, conditional indexes, and restrictive clauses to optimize your queries.

Example:

// 使用索引
$products = $em->getRepository('App\Entity\Product')
    ->findByCategory($category, ['name' => 'ASC']);

// 使用限制性子句
$products = $em->getRepository('App\Entity\Product')
    ->findByCategory($category, ['name' => 'ASC'])
    ->setMaxResults(10);

Reduce HTTP requests

Each HTTP request requires server resources, so reducing the number of requests can significantly improve performance. Merging images, using CSS Sprites, and loading content via Ajax are some ways to reduce requests.

Example:

// 合并图像
$image = new Imagick();
foreach ($images as $filename) {
    $image->addImage(new Imagick($filename));
}
$image->imageWrite('all.png');

Enable GZIP compression

GZIP is a data compression technology that reduces the size of HTTP responses. Enabling GZIP can significantly reduce bandwidth usage and increase page load speeds.

Example:

// 在 Apache 中启用 GZIP
<IfModule mod_deflate.c>
    SetOutputFilter DEFLATE
    DeflateFilterNote mime x-deflate
    DeflateType text/html text/css application/javascript application/json
</IfModule>

Practical case

After applying these techniques on a large e-commerce website, here are some recorded improvements:

• Page load time reduced by 40%
• The number of database queries reduced by 50%
• The number of HTTP requests reduced by 20%
• Server resource consumption reduced By 25%

By implementing these performance optimization techniques, you can significantly improve the performance of your PHP e-commerce website, thereby enhancing customer experience and increasing conversion rates.
