Why Optimize PHP?
High-traffic websites require optimized PHP code to handle large volumes of requests efficiently. Here are key techniques.
1. Use an Opcode Cache
Enable OPcache to store precompiled script bytecode:
opcache.enable=1 opcache.memory_consumption=128
2. Optimize Database Queries
Use indexing and avoid SELECT * to reduce query time:
SELECT id, name FROM users WHERE active = 1;
3. Implement Caching
Use tools like Redis or Memcached to cache frequently accessed data.
4. Lazy Loading
Load resources only when needed to reduce server load.
Conclusion
Optimizing PHP performance ensures your site remains fast and scalable. Combine these techniques for the best results.
