Want to improve user experience? This blog provides 10 steps you can take to increase PHP performance via ongoing PHP tuning and other strategies.
If you’re still running applications on PHP 5.6, upgrading to PHP 7.3 or PHP 7.4 will significantly speed performance. For example, upgrading a PHP 5.6 application to PHP 7.3 typically doubles or triples application performance. Organizations are also reporting measurable performance gains by upgrading applications from PHP 7.3 to PHP 7.4.
For more information, you can read about the new features in PHP 7.4 and how to upgrade your PHP applications.
PHP tuning is easier when you have detailed insight into application code, including metrics about page load times, database queries, and other potential bottlenecks. Zend Server includes the industry-leading PHP debugger, Z-Ray. With it, you can left-shift PHP tuning, so you can identify and resolve issues before they can impact user experience.
For example, with Z-Ray, you can:
PHP was originally developed to support synchronous code that completes one task at a time, in sequential steps. However, PHP — and other languages — have evolved to support asynchronous PHP code, which enables the completion of more than one task at a time.
You can dramatically boost performance by using asynchronous PHP instead of synchronous PHP. In some benchmarks, PHP application throughput increases by 100 times, by enabling asynchronous PHP via Swoole, instead of using a process accelerator such as php-fpm with synchronous code. Learn more about asynchronous PHP.
Uncovering bottlenecks is critical for increasing application speed. However, to resolve them, a developer needs to know which lines of code need to be rewritten. Zend Server provides a Code Tracing tool that is like an aircraft black box for PHP applications. It records and plays back the execution history of your PHP applications so you can:
In addition, you can:
You can increase application speed via ongoing PHP tuning. However, PHP tuning is easier when you pinpoint where improvements are needed. It's also helpful to be able to instantly measure the effect of code and configuration changes.
Get the real-time PHP application insights you need to simplify PHP tuning by using Zend Server’s URL Insights tool. It can continually monitor your PHP applications and websites, and provide real-time insights about traffic and performance, including:
In addition, you can take advantage of the Performance Audit Service from Zend to get expert analysis and recommendations for improving your PHP:
You can increase application speed by caching specific pages and data types. Caching pages eliminates unnecessary page loading — such as when the same file is used to redirect to several pages. When it is impractical or impossible to cache the entire page output, you can use data caching.
Using tools in Zend Server, you can easily cache:
You can also specify where you want data cached, such as in shared memory, on disk, or in namespaces — when you use Zend Server.
Being able to control when certain types of application jobs run can be extremely useful for maintaining real-time performance during peak usage times. For example, if you have an e-commerce store with a catalog that needs to be periodically re-indexed, you can schedule this process to run overnight.
You can schedule offline asynchronous processing of tasks and activities, using a tool called Job Queue in Zend Server. This includes being able to:
Unpredictable spikes in traffic can dramatically slow down performance, unless you use clustering technologies that flex to support changes in demand. However, clusters can be challenging to setup and manage.
Zend Server provides a Session Clustering tool that can help improve application performance, ensure application uptime, and save time. With it, you can:
As a PHP application server, Zend Server works closely with a web server to rapidly process application requests. Which web server you choose is critical for ensuring the best possible performance.
Modern web servers such as NGINX and Apache, deliver built-in capabilities that accelerate performance including load balancing and caching. Zend Server works seamlessly with these and other web servers. Zend Server also supports automated setup of PHP on NGINX and Apache, saving you more time.
Optimum application performance requires PHP runtimes that include bug fixes and security patches. However, the community only provides comprehensive support for runtimes for two years after their initial release.
You can boost the performance of your PHP applications by using ZendPHP, the certified and secured PHP stack that comes with Zend Server. ZendPHP provides:
