Broken functionality
Fatal errors, blank pages, failed forms, broken logins, checkout problems and database connection failures.
Legacy PHP modernization
Upgrade your PHP.
Preserve your website.
Protect your business.
Outdated PHP shouldn't force you to choose between security and a working website. Our PHP developers and security specialists analyze legacy applications, repair compatibility issues and test the upgrade in an isolated environment before production deployment.
Custom PHPWordPress & JoomlaFrameworks & CMS
The compatibility challenge
Why simply changing PHP versions can break your website.
Older sites may rely on removed PHP functions, abandoned plugins, obsolete database APIs and frameworks that cannot run unchanged on modern PHP. Unsupported PHP branches no longer receive routine upstream security fixes, though some vendors provide extended patches. We find the real blockers and plan a safe path forward.
Legacy dependencies
Unsupported CMS releases, themes, plugins, frameworks, extensions and third-party integrations.
Security exposure
End-of-life runtimes and vulnerable application components increase operational risk and maintenance burden.
What we modernize
Compatibility solutions for more than just WordPress.
Custom PHP applications
Legacy PHP 5.x/7.x sites, bespoke portals, database-driven business systems, custom integrations and obsolete function replacements.
WordPress & WooCommerce
Core, themes, plugins, page builders, custom code, checkout workflows and integration compatibility.
Joomla & other CMS
Joomla, Drupal, OpenCart, PrestaShop, Magento and other PHP-based CMS platforms, with supported migration paths.
PHP frameworks
Laravel, Symfony, CodeIgniter, Yii and CakePHP framework and dependency upgrades.
Emergency recovery
Investigate websites that stopped working after a hosting provider changed the PHP runtime.
Complex modernization
Partial redevelopment and component replacement when a direct compatibility upgrade is not feasible.
Staging-first delivery
Investigate, repair and validate before going live.
We work on a protected copy of your application and coordinate production changes only after agreed testing and customer approval.
Website assessment
Identify PHP, CMS, database and application dependencies, critical functionality and likely migration risks.
Secure staging restoration
Restore authorized files and database backups into an isolated environment with sensitive integrations controlled.
Compatibility investigation
Review runtime errors, obsolete functions, libraries and extensions; agree the target PHP version and remediation scope.
Code remediation
Update code and compatible dependencies, replace obsolete components where feasible and preserve agreed business logic.
Functional and security testing
Check forms, authentication, databases, APIs, scheduled jobs, payments and other agreed critical workflows.
Customer acceptance
Provide a staging review and resolve agreed findings before production changes.
Production deployment
Take a fresh backup, coordinate maintenance and data synchronization, verify the release and retain a rollback plan.
Post-upgrade support
Investigate upgrade-related defects during the agreed post-deployment support period.
Why HostGree
Developers, PHP specialists and server engineers working together.
Isolated testing infrastructure
Controlled staging environments help us investigate compatibility without experimenting on your live website.
Full-stack expertise
PHP development, website security and administration across Linux, Windows, cPanel, Plesk, Webuzo, Apache and Nginx.
Hosting-independent support
You can retain your existing hosting provider, subject to suitable server access and PHP runtime availability.
Tailored engagements
Every upgrade is quoted to fit the actual application.
No fixed packages or surprise assumptions. We review your requirements, propose an appropriate technical scope and provide a customized quotation before chargeable work begins.
Compatibility Assessment
Technical discovery, compatibility findings, recommended target PHP version and a remediation roadmap.
Upgrade & Remediation
Agreed code changes, staging validation, customer review and coordinated deployment.
Advanced Modernization
Complex framework migrations, unsupported components, integrations and partial redevelopment.
A preliminary discussion helps define the assessment scope. Detailed investigation and development are separately quoted. Some applications may require redevelopment rather than a direct upgrade.
Frequently asked questions
Questions about upgrading legacy PHP
Can you upgrade a PHP 5.6 or PHP 7.4 website?
Often yes, depending on its code, extensions and third-party dependencies. We assess the application and recommend a supported PHP target before estimating the work.
Will my website go offline?
Most development occurs on staging. Final deployment may require an agreed maintenance window, and zero downtime cannot be guaranteed.
Can you keep my existing website design?
Preserving the design and business functions is our goal. We discuss any necessary replacement or redevelopment of unsupported components first.
Do I need to move hosting to HostGree?
No. We can work with your existing provider if the environment and access support the agreed deployment.
Does a PHP upgrade make my site completely secure?
No. Supported PHP reduces runtime exposure, but application code, plugins and server configuration may need separate security remediation.
How much does it cost?
We prepare a project-specific quotation after an initial review of complexity, dependencies and the required scope.
Ready to modernize?
Don't let legacy PHP hold your website back.
Tell us your website URL, current PHP version (if known), platform and the problem you're facing. Please do not email passwords or sensitive backups; secure access can be arranged after scoping.
