I will upgrade PHP and fix compatibility bugs

Need to update PHP without breaking your application?

I review one PHP application, identify upgrade blockers, fix an agreed compatibility issue, and document a controlled update with rollback steps.

Basic: one app/runtime and dependency readiness review with a written plan. Diagnosis only; no code fix or deployment.

Standard: one reproducible compatibility defect fixed on staging, with a regression check and code handover.

Premium: one small app update path, up to two agreed compatibility fixes, smoke checks and deployment/rollback notes. Production changes need your approval.

Message me before ordering with your PHP version, hosting, framework and symptoms. We agree the target version and acceptance checks first.

Updates follow current PHP or hosting-vendor guidance. This is not penetration testing, incident response, malware cleanup or a guarantee of complete security or zero downtime. Large framework migrations, licenses, hosting and third-party fees are separate. Do not send passwords or production data in the initial brief.
