Why PHP version matters

Each PHP version follows a specific lifecycle, going through different support phases before reaching its end of life. Using an unsupported version exposes your site to major security risks.

For about 2 years after its release, the version receives regular bug and security fixes.

Security Fixes Only

For about 1 additional year, only critical security fixes are published.

End of Life (EOL)

After this period, no updates are published, even for critical vulnerabilities.

Newer versions of WordPress and plugins require recent PHP versions to function properly.

Reduced performance

Recent PHP versions offer significant performance improvements, up to 3x faster than older versions.
