PHP is a server scripting language, and a powerful tool for making dynamic and interactive Web pages. It is a widely-used, free, and efficient.
PHP is an open-source programming language that our websites use to run internal functions and process database information. It is installed directly on your web server and managed by your web host. PHP is a living project and is constantly being updated and patched for bug and security vulnerabilities. Newer PHP versions fix these vulnerabilities and optimize the processing and delivery of your website content. This means that the PHP version your website runs on, directly affects the security, speed and performance of your site.
Support for PHP 7
Each release branch of PHP is fully supported for two years from its initial stable release. During this period, bugs and security issues that have been reported are fixed and are released in regular point releases. After this two year period of active support, each branch is then supported for an additional year for critical security issues only. Releases during this period are made on an as-needed basis: there may be multiple point releases, or none, depending on the number of reports. Once the three years of support are completed, the branch reaches its end of life and is no longer supported. A table of end of life branches is available.
2 Times Faster
PHP 7.0 removed many outdated functions that were dragging down older versions, making it more efficient than ever before, and 7.2 takes it even further. This new, leaner version of PHP allows your site to load and respond much faster than previous versions. As an example, PHP 7.2 can serve up to 3x as many requests per second and handle more traffic with the same number of resources. It can handle uncached site visits over 2 times faster than PHP 5.5. Of course, media and template-specific factors will still highly influence your site load times, so be sure your whole site is optimized for quick loading.
PHP 5 had a lot of security issues that got patched up over time. If your site is running an earlier version of PHP, some of these vulnerabilities might still be present! And cybercriminals are very aware of these vulnerabilities — they actually look for sites running these earlier versions so they can stage easy attacks. Much of the flak your website gets for “being insecure” is due to servers and sites still running unpatched versions of PHP. PHP 5.4 hasn’t been updated since 2015 — giving hackers 3 whole years to discover and exploit vulnerabilities that might never be patched on sites running on it. PHP 7 introduced new security features as well, including stronger hashing and encrypting for storage of sensitive data, and better functionality for identifying content that is potentially dangerous like malicious code injections.
This leaner, more efficient version of PHP means a significant improvement in how code is processed on the server: up to a 75% reduction in the number of commands issued when performing a single task. Your server has a set amount of memory available for running PHP on your site. CMS core, design, and app files all require varying amounts of that memory to run; the more complex the task, the more memory is required. And when they hit that limit of memory on your server — up comes the White Screen of Death with an error message. Upgrading to PHP 7 means much less memory is required, allowing more better stuff to happen on your site.
