Which PHP versions does JetHost support?

JetHost keeps every mainstream PHP branch online so you can match each project’s needs – from the newest 8‑series builds down to legacy 5.6 for very old code.

Supported PHP versions

PHP Version – Notes / ideal use‑case
8.4 – Preview build for testing upcoming language features.
8.3 – Default on new accounts; best balance of speed and security.
8.2 – Recommended fallback if a plugin isn’t 8.3‑ready.
8.1 – For applications that still rely on specific extensions not updated for 8.2+.
8.0 – Useful when code needs minor updates before jumping to 8.x newer.
7.4 – 7.0 – Maintains compatibility for established sites awaiting upgrades.
5.6 – Keeps critical legacy applications online while you refactor.

Quick tips

Stay current: Target 8.3 (or 8.4 when stable) for speed and full vendor support.
Stage before big jumps: Clone the site to a subdomain, switch PHP there, and test thoroughly.
Watch your logs: Deprecated warnings signal code that won’t run on future releases.
Back up first: Use Backup Wizard or JetBackup to grab a full snapshot before switching.
Upgrade plans: If you’re still on 7.x or 5.6, start scheduling a migration—newer PHP versions deliver major performance and security gains.

Choose the version that best matches your site’s codebase and performance goals, and test any upgrade on a staging copy before applying it in production.
