I will fix legacy PHP code and upgrade PHP compatibility
Sebastiano C
Level 1
Over deze dienst
Did a PHP upgrade break an older application, form or database workflow?
I repair legacy PHP compatibility issues and modernize agreed parts of existing code so you can move toward a supported PHP environment without an unnecessary full rewrite.
Work may include replacing obsolete functions, adapting database access, repairing sessions or forms, and updating compatible dependencies. The starting version, target version, module and test cases are agreed before work starts.
Basic fixes one defined compatibility issue in a small script. Standard upgrades one workflow. Premium modernizes one bounded module with up to three agreed workflows.
You receive the code changes, test results, dependency notes and a handover with known limitations.
Work is performed in an agreed test environment. Full rewrites, every dependency in an application, hosting migration, production deployment, security certification and zero-downtime guarantees are not included.
Please send your PHP versions, errors and a description of the affected workflow before ordering. Large or undocumented systems may need a separate paid assessment before implementation can be quoted.

I help businesses fix and modernize PHP and Laravel applications they already depend on. With 15+ years of backend experience, I troubleshoot production errors, stabilize MySQL databases, improve performance, repair API/payment integrations, and upgrade legacy code without disrupting existing workflows.
Recent work includes production database stabilization, payment integration fixes, and custom document-processing systems.
I diagnose the root cause, explain the options, and deliver scoped, tested changes. Message me with your stack and issue before ordering.

Veelgestelde vragen
Is this a full rewrite of my application?
No. These packages cover defined compatibility repairs or modernization of an agreed workflow or module. A complete rewrite, new architecture or full-system migration needs a separate project scope.
Which PHP version will you upgrade to?
We agree on a supported target after checking your code, dependencies and hosting. The newest release is not automatically the best fit. Unsupported or incompatible dependencies may require a replacement or additional work.
Can you repair code using obsolete PHP functions?
Yes, where the required changes fit the agreed scope. Examples include obsolete functions, database access and compatibility-related errors. I check how the affected code is used before quoting implementation.
Does the price cover every file and dependency?
No. Each package covers the named script, workflow or module and the dependencies explicitly agreed before ordering. An application-wide upgrade, undocumented integrations or extra modules require a separate quote.
Can you guarantee no downtime or no regressions?
No absolute guarantee is possible for unknown legacy systems. I test the agreed workflows in a test environment and document remaining limits. Production deployment needs a separate backup, rollback and release plan.
Do you work with Laravel or WordPress?
For a Laravel application bug, my dedicated Laravel service is the better fit. This service focuses on legacy PHP compatibility. Framework, plugin and theme upgrades must be assessed separately; they are not automatically included.
What happens if the system cannot be scoped in advance?
I can propose a separate paid assessment with compatibility findings, risks and an implementation plan. Its price and deliverables are agreed before ordering. Assessment does not imply that a complete upgrade is included.
What is included in a revision?
Adjustments to meet the original compatibility target and agreed acceptance tests. New modules, changed target versions, extra functionality and unrelated defects are additional scope. Source changes and test notes are included in every package.
