FAQ
What access do you need to fix PHP errors?
I usually need access to hosting/cPanel, FTP/SSH, or source code to identify and fix the issue. If you’re not comfortable sharing direct access, you can provide the error logs or project files.
Which PHP frameworks do you support?
I work with Laravel, CodeIgniter, CakePHP, and custom PHP applications. If you’re unsure about your setup, send me details and I’ll confirm.
Can you fix urgent PHP issues?
Yes! I provide priority support for urgent errors such as site downtime, fatal errors, or broken features. Please select the Premium package or add the “Priority Support” extra.
Do you provide ongoing maintenance?
Yes, I can provide long-term PHP support, including regular updates, code optimization, and security monitoring. This is included in my Premium package and available as a custom offer.
What if my issue is larger than expected?
If the problem requires more time than the chosen package allows, I’ll inform you promptly and suggest upgrading or creating a custom order.
What if I need more than just bug fixing?
I also offer feature development, optimization, and full project support. Let me know your requirements and I can send you a custom quote.

Absolutely, including replacements for deprecated functions and compatibility fixes.
