FAQ
Do you use raw MySQL queries or secure PDO?
All database interactions are written using prepared PDO (PHP Data Objects) statements to ensure robust protection against SQL injection vulnerabilities.
Can you connect my custom Core PHP backend to an existing frontend?
Yes. I can build structured RESTful API endpoints returning clean JSON data to connect seamlessly with React, Next.js, mobile apps, or static HTML/JavaScript frontends.
Do you upgrade outdated PHP code to PHP 8+?
Yes, I can review legacy codebases, replace deprecated functions, fix compatibility errors, and update scripts to run smoothly on modern PHP 8.x environments.
Will you deploy the code to my live server?
Yes. If you provide cPanel, FTP, SSH, or server access, I can deploy the script or full application and configure the database on your hosting environment.
