About this gig
Is your website running on an outdated PHP version?
Old PHP applications can face security vulnerabilities, unsupported dependencies, and compatibility issues. Upgrading a legacy application can be challenging when your business depends on existing features working correctly.

- Upgrade PHP 5.x, 7.x, or older 8.x applications, subject to compatibility assessment.
- Identify PHP version and dependency-related security risks.
- Fix PHP compatibility errors and deprecated code.
- Upgrade legacy Laravel and CakePHP applications.
- Update incompatible Composer packages and dependencies.
- Troubleshoot errors after a PHP version upgrade.
- Test key application features and resolve upgrade-related issues.
- Provide a summary of changes and outstanding security concerns.
My upgrade process
- Review your current PHP version, framework, dependencies, and application requirements.
- Identify upgrade blockers and potential security risks.
- Prepare an upgrade plan based on your application's condition.
- Implement agreed changes

FAQ
Can you upgrade PHP 5 or PHP 7 applications?
Yes, subject to a code and dependency assessment. Older applications may require substantial compatibility changes before they can run on a supported PHP release.
Can you fix the latest PHP security vulnerabilities?
I can assess your PHP environment, identify applicable updates, and help apply available fixes. The exact remediation depends on the installed PHP build, operating system, hosting provider, and application architecture.
Will my website continue working after the upgrade?
I will test the agreed critical workflows and address upgrade-related issues within the package scope. However, no developer can guarantee that every application will remain entirely issue-free without comprehensive testing.
Do you work with Laravel and CakePHP?
Yes. The service can cover Laravel, CakePHP, and custom PHP applications, subject to the project's requirements and framework compatibility.
