FAQ
Which PHP versions can you upgrade to?
I can update code from older versions (PHP 5.x and 7.x) to modern PHP 8.x. Tell me your current and target versions.
Will my website break during the update?
I work on a copy, never your live site, and test before handing it over. You deploy it once you’re happy.
Can you fix old mysql_ functions?*
Yes. These were removed from modern PHP. I replace them with PDO or MySQLi using prepared statements, which also improves security.
Can you fix forms and AJAX that stopped working?
Yes. That includes validation, submission errors, dynamic forms and old jQuery or JavaScript code.
Can you make my old HTML responsive?
Yes. I can update old HTML to clean HTML5 and make it work on phones and tablets.
What do I need to send?
Your code files (zip or repository), a database export if needed, your PHP version, and a description of the problem or goal.
Can you also fix security problems?
Yes. I check for common issues like SQL injection, XSS and weak password handling. The Premium package includes this.
Will you explain what you changed?
Standard and Premium include a short change report, and I add clear comments in the code.
Why contact you before ordering?
Legacy projects vary a lot. A quick look at your code lets me quote accurately and avoid surprises.

Ongoing collaborationSeller did as required but was receiving strange PHP errors even though result was correct. Seller begun to argue that he had done his job and it was not his issue to deal with. Very disappointed with how quickly he changed his attitude toward me. Previous experiences were good, this one has changed my mind.
