I have the source code for a website I built several years ago. It currently has some issues, most likely because it was built using an older PHP version and is no longer fully compatible with current environments. I'm looking for an experienced PHP developer who can identify the issues and get the website working properly again. I believe this should be a relatively small task for someone experienced with legacy PHP, possibly around 2–3 hours. IMPORTANT: I do not want to share or upload the source code with anyone. The work must be done directly on my computer through a remote-access tool such as AnyDesk or TeamViewer. You will be able to inspect, debug, modify, and test the code remotely on my machine. More details about the errors and environment will be shared in chat. Please bid only if you are comfortable working remotely on my machine and have experience debugging older PHP projects.

Hi, This is Elias from Miami. I checked your project description and understand you have an older PHP website that no longer works correctly in a modern environment, and you want it diagnosed and fixed directly on your computer without sharing the source code. I have experience debugging PHP applications, resolving version compatibility issues, dependency problems, deprecated functions, database errors, and server configuration issues. I’m comfortable working through AnyDesk or TeamViewer. I’d first reproduce the errors and confirm the PHP/database environment, then trace and fix compatibility issues while keeping changes minimal so the existing application behavior remains intact. I’d be happy to review the errors with you and can work entirely on your machine. I have a few questions for clarification: Q1 – Which PHP version was the site originally built for, if known? Q2 – What PHP version are you trying to run it on now? Q3 – Is the website currently running locally, or do we also need to configure the local server/database environment? Looking forward to hearing from you.

I’ve handled similar cases where older PHP code stopped working after server or version upgrades. Usually, the issues come down to deprecated functions, changed error handling, or outdated libraries. Since you want the work done directly on your machine, I’m comfortable with AnyDesk or TeamViewer setups. I’d start by reviewing your PHP version and error logs, then identify incompatible code parts and update them for compatibility with your environment. To be efficient, can you share which PHP version the code was originally written for and your current environment’s PHP version? Also, do you already see specific error messages when running the site? This type of fix typically takes just a few hours if no major rewrites are needed. Once connected remotely, I’ll go through debugging and testing so the site works smoothly again. I’m ready to start as soon as you’re set up for remote access.

Hello the main issue is usually not the PHP upgrade itself, but finding which legacy functions, dependencies, database calls or configuration changes are breaking under the newer PHP environment. I can inspect the existing application directly through AnyDesk or TeamViewer, identify the compatibility issues, update the affected PHP/JavaScript code and database queries, then test the main website flows to make sure the upgrade does not introduce new problems. I’m comfortable working with older PHP applications and can keep the changes focused rather than unnecessarily rewriting stable parts. Once the errors are resolved, I’ll verify the environment and explain the changes made so the site remains maintainable. Looking forward to work with you. Thanks

Hi, I looked at your requirements and the main challenge is identifying which parts of the legacy PHP code are breaking under the current PHP environment without changing working behavior unnecessarily. I’d inspect the errors directly on your machine, trace compatibility issues across PHP, MySQL and related dependencies, apply focused fixes, and test the affected flows after each change. I’m comfortable working through AnyDesk or TeamViewer and keeping the work limited to what is actually needed. Quick questions: Q1. Which PHP version is the website currently running on, and which version are you trying to upgrade to? Q2. Do you already have the main error messages or affected pages identified? These will help me prepare for the remote debugging session and avoid unnecessary changes. I’m ready to inspect the issue and get the existing site working again. Fernando
