PHP e-commerce system development: performance optimization strategies

Optimization strategy: Database optimization: use indexes to speed up queries. Cache query result sets. Use persistent connections. Code optimization: avoid N+1 queries. Use lazy loading optimization algorithms. Front-end optimization: shrink and compress files. Cache static resources. Optimize image size and quality.

PHP e-commerce system development: performance optimization strategy

Optimizing e-commerce system performance is crucial to improving website speed and user experience important. This article will introduce some key optimization strategies for PHP e-commerce systems.

1. Database optimization

• Use indexes: Appropriate use of indexes can significantly speed up database queries. Add indexes based on frequently queried fields.
• Cache queries: Cache frequently executed query result sets to avoid repeated execution of expensive database operations.
• Use persistent connections: Establishing a persistent database connection instead of establishing a new connection for each query can improve performance.

Code Optimization

• Avoid N+1 queries: use a single query to get all the necessary data at once instead of executing it for each entity Multiple queries.
• Use lazy loading: only load data when needed to reduce page loading time.
• Optimize algorithms: Review code and optimize resource-intensive algorithms to improve efficiency.

Front-End Optimization

• Minify and Compress: Minify JS and CSS files to reduce file size and increase loading speed.
• Cache static resources: cache images, CSS and script files to avoid repeated downloads.
• Optimize images: Compress and resize images to reduce page size.

Practical case:

Cache query result set:

<?php
// 缓存结果集
$cacheKey = 'products_by_category_' . $categoryId;
$cachedResults = cache()->get($cacheKey);

// 如果缓存未命中，运行查询
if (!$cachedResults) {
    $cachedResults = $productRepository->findByCategory($categoryId);
    cache()->set($cacheKey, $cachedResults, 600); // 缓存 10 分钟
}

// 返回缓存结果
return $cachedResults;
?>

Optimize images:

function optimizeImage($imagePath)
{
    // 压缩图像以减少文件大小
    $newImage = imagecreatefromjpeg($imagePath);
    imagejpeg($newImage, $imagePath, 85);

    // 调整图像大小以适合缩略图
    $thumbWidth = 200;
    $thumbHeight = 200;
    $newThumbImage = imagecreatetruecolor($thumbWidth, $thumbHeight);
    imagecopyresampled($newThumbImage, $newImage, 0, 0, 0, 0, $thumbWidth, $thumbHeight, imagesx($newImage), imagesy($newImage));

    imagedestroy($newImage);

    return $newThumbImage;
}

By implementing these strategies, you can significantly improve the performance of your PHP e-commerce system, thereby improving user experience and increasing conversion rates.
