Enhancing PHP Performance: Best Practices for Optimizing PHP Applications

To improve PHP performance, it is important to deliver efficient, fast, and scalable web applications. PHP is a widely used scripting language of server-side that powers quite significant websites and web apps around the world. But to optimize the PHP performance could become a daunting task, specifically for the teams that are building new apps. It’s with the adoption of certain practices that the developers will be able to significantly enhance the PHP performance. The given article here, delves into such best practices, offering some actionable insights for helping one in the optimization of the PHP apps effectively.

Improve PHP App Performance with Best Practices

When building new apps, certain best practices can help with the PHP app’s performance. A discussion about this is made below.

Code Optimization

Web application code optimization is an overlooked way to improve PHP performance. Certain suggestions to help out with it are,

  • Choose the performant PHP framework that supports natively high-performant architectures like Mezzio, Symfony 6.x, etc.
  • Coding the app for being stateless instead of using the session mechanism, could bloat the memory use.
  • Use the optimized and native SQL queries.
  • Prevent memory exhaustion.

Transitioning to HTTP/2

It again is the best way to improve PHP performance to support the HTTP requests. In comparison to the HTTP/1.x, the HTTP/2 is much more powerful. It provides better performance for web apps. Further, as per the PHP development company, there are many other advantages associated with it, too. The list includes,

  • Allowing the request prioritization.
  • Including the protocol enhancements for better performance.
  • Reduction in latency by enabling request and response multiplexing.
  • Compressing HTTP header fields to reduce overhead.


For PHP app performance, it’s an important aspect. It includes hosting file versions within a temporary storage location for reduction of latency and bandwidth consumption. It can improve both user experience and app performance. Further, when developing the cache strategy, certain techniques to be followed are,

  • HTTP caching
  • Database caching
  • Network caching
  • Reverse proxy server caching.

Focusing upon 1st Mobile Devices and 2nd Desktop

Optimizing user performance and experience for mobile devices is more difficult than for desktop ones. To focus on mobile devices is better. It can be done by removing the common performance bottlenecks and also site testing on mobile devices. The approach will help simplify desktop optimization later.

Front-End Optimization

HTTPS requests are used by web browsers for fetching web page parts from web servers, like scripts, stylesheets, and images. To handle large graphic files improperly would slow the load times of websites.

Certain examples for consideration when optimizing the web front-end are- combining varied JavaScript and CSS files within a single bundle; optimization of images with the choice of appropriate resolutions for varied devices, etc. If you hire a dedicated PHP developer, you have nothing to worry about. They handle it all, without letting you make the tough decisions.

Best Practices for Tuning PHP Performance for Existing Applications

Some key software engineering decisions can be made for better web app performance. Further, the use of the right tools is also required. All that’s needed to do is choose the right development framework for creating necessary architectural convergence centered around performance.

Coding Profile

Profiling, it’s a form of dynamic program analysis. It measures certain aspects, including memory use and functional call durations. To profile helps with the identification of the code bottlenecks and the areas for optimization.

Code Refractor

After the bottlenecks are identified through profiling and monitoring tools, the code is to be refactored to eliminate issues. Certain common use cases for refactoring include the optimization of DB queries and the memory footprint minimization by avoiding the loops in specific ones associated with the DB queries.

Evaluating & Optimizing Caching Strategies

Good code monitoring tool, it helps to understand the cache hit and miss and also the performance gains via caching strategies that are applied at code level. It can be DB query caching and page caching. Ensure to continuously refine the caching strategies for delivering the best performance.

Inspection & Optimization of Server Configuration

Monitoring the tools could offer insights into how the server configurations could be enhanced for better performance. Optimizing the aspects, including filesystem access, memory usage, DB query connections, and server configurations, will help to optimize the overall performance.

Writing Clean Code

Concise and simple clean code is easy for the compiler and the programmer to understand and optimize. So, aim to write code that is easy to understand and read without the need for additional references.

Using the Right Types of Data

Using the correct type of data will help to minimize the conversations and make the code efficient. So, use the smallest data type, which can represent data being worked upon accurately.

Avoiding Unwanted I/O

Make sure that the code only reads from and also writes to the filesystem when it is necessary. To consider the use of asynchronous/deferred jobs for the I/O operations is important to improve PHP performance.

Using the Latest Version of PHP

As per the PHP development company, wherever possible use the latest versions to guarantee the best performance for the PHP apps. The new versions will come with some significant amount of improvement in the performance, like the JIT compiler that’s introduced in the PHP 8.

Final Words

To improve PHP performance, it’s important to build efficient, faster, and scalable web apps. Ensuring to adoption of the best practices, whether beginning the new project or ensuring to maintenance of the existing app, can significantly create an enhancement of the performance of PHP apps. No matter whether you hire a dedicated PHP developer or decide to work with the company, all of the strategies mentioned above ensure the apps run efficiently and smoothly, therefore offering the best user experience.
