Use

The mail() function in PHP can be used to send emails from a webserver. The function accepts parameters for the recipient email address, subject, message, headers, and parameters.

Important Points

• The mail() function requires a running mail server on the machine.
• The mail() function may be disabled on some shared hosting servers due to security reasons.
• The to parameter should contain only one email address. In case of multiple recipients, the Bcc header should be used.
• Avoid using any user-supplied values in the headers parameter due to security reasons.

Summary

The mail() function in PHP is used to send an email to one or more recipients. It requires the email address of the receiver, the subject, message, and headers. The function returns true if the email is accepted for delivery and false otherwise.
