Hello, I am Chris Pine. I am digital marketing specialist and freelancer. PHP web development refers to the process of creating web applications and websites using PHP programming language. With PHP, developers can create dynamic web pages and interactive web applications that can interact with databases, process forms, and handle user input. PHP can be integrated with other technologies such as HTML, CSS, and JavaScript to create a complete web application. PHP is an open-source language, meaning that it is free to use and there are many libraries and frameworks available to help developers build high-quality web applications quickly and efficiently.
