PHP mail is a function in the PHP programming language used for sending emails directly from a web server. This function allows a PHP script to send emails to recipients with options for setting the sender, recipient, subject, and body of the message. It's widely used in web development for contact forms, notifications, and automated responses. However, PHP mail's simplicity can lead to challenges like handling spam, deliverability issues, and lack of advanced features, leading many to opt for more robust mail handling libraries or external mail services.
