Here’s why it matters:
1. Security Risks
Older PHP versions eventually stop receiving security patches. That means vulnerabilities stay open — and attackers know exactly how to exploit them.
2. Performance Loss
Newer PHP versions are significantly faster. Running outdated PHP can slow your site down even if everything looks fine on the surface.
3. Plugin & Theme Incompatibility
Developers optimise for current versions. If your PHP or WordPress version is too old, updates can break features — or stop working entirely.
4. Unexpected Costs
Some hosting providers charge extra for “extended support” of outdated PHP versions. In some cases, they even force‑upgrade your site, which can cause issues if you’re not prepared.
5. Avoiding Update Problems
Regular checks help you catch small issues before they turn into major outages. A quick review every few months can save a lot of headaches.
It’s always worth checking your setup occasionally — or having someone check it for you — to keep your site secure, stable and future‑proof.
