PHP Website Contact Form (Fixed Recipient)

This project is a production-ready contact form developed in PHP, designed to be integrated into a client website.

Unlike a generic contact form where the message is sent to an arbitrary recipient, this implementation sends all messages to a fixed email address configured in the backend, which is the standard behavior for website contact forms.

The sender’s email is collected to allow replies, not to define the destination.

Key Concept

• Recipient email is configured in PHP
• Sender email is provided by the user

  • HTML5 required fields
