PHP language

PHP (Hypertext Preprocessor) is a server-side scripting language often embedded in HTML and widely used for web development. It powers everything from small personal sites to major content platforms, thanks to its ease of use and deep integration with web servers like Apache and Nginx.  

In the context of email, PHP allows developers to: 

  • Send messages using native functions like mail()  
  • Connect to email APIs (like Mailgun’s) via HTTP requests  
  • Handle inbound email events, webhooks, and routing logic on the backend  

While mail() works for basic use cases, we recommend using a dedicated email API (like Mailgun’s SDK for PHP) to ensure proper authentication, logging, and deliverability tracking.
