2. Open Source: It is a free and open-source language that can be altered to meet certain requirements. A sizable developer community is involved in both development and support for it.
3. Integration: PHP is easily integrated with other technologies, including web servers (like Apache, Nginx), databases (like MySQL, PostgreSQL), and numerous protocols..
