Better Performance
Upgrade to PHP 8.4 for up to 500% faster performance compared to 5.X, 200% faster than 7.X, or 40% faster than 8.2 — enabling your app to handle more users or cut server costs by up to 80%.
Running an outdated PHP version can slow down your application and expose it to serious risks. According to php.net, only PHP 8.3 and 8.4 are actively supported as of May 2025, with security updates provided. Versions 8.1 and 8.2 are in a "recommended to update" state, receiving limited security fixes, while 8.0, 7.X and older (like 5.X) are completely unsupported — leaving them vulnerable to attacks. A recent PHP Foundation audit (April 2025) uncovered several security issues in the PHP core, which are only being patched in supported versions.
If you’re in healthcare, fintech or other high-risk fields, where security is non-negotiable, delaying an upgrade isn’t just risky; it’s a lawsuit waiting to happen. You might be vulnerable — check the graph below to see if your version is up to date. If not, Accesto can help with a seamless upgrade to keep your app secure and performant.
I’ve overseen countless PHP upgrades, and I can tell you the process is smoother than most businesses fear. Why upgrade? Beyond the obvious performance boosts — like the 35% faster response times we achieved for Event Tickets or the 4x overall improvement for MediaHQ — modern PHP versions unlock new possibilities that let your developers work smarter, not harder. The sooner you act, the easier future upgrades will be, and the more competitive your business will become.

Upgrading to PHP 8.3 or 8.4 eliminates vulnerabilities. Recent PHP Foundation audits, conducted in cooperation with a German government-backed agency (April 2025), confirmed the necessity of fixes for critical security holes unavailable in unsupported versions like 7.X and 5.X.
