I've been working on a PHP project recently and I'm looking for some suggestions to optimize the performance of my code. I want to make sure that my application runs smoothly and efficiently. I have implemented certain techniques like caching, code refactoring, and database query optimization, but I feel like there might be more to learn.
I have noticed that my PHP code sometimes takes longer to execute, especially when there are a large number of users accessing the application simultaneously. This results in slower page loads and a less than ideal user experience.
I would greatly appreciate any tips, best practices, or advice on optimizing PHP code for better performance. Are there any specific coding techniques or tools that you recommend? How can I identify and resolve potential bottlenecks in my code? Are there any popular PHP frameworks that can provide performance improvements?
Also, if there are any common mistakes that developers tend to make in terms of performance, I would love to know about them as well.
Thank you in advance for your help!
