How to Send Email using PHP mail() Function [SMTP]

Updated on December 20, 2018     Kisan Patel

The SMTP mail settings can be configured from “php.ini” file in the PHP installation folder.

Find “mail function” in php.ini file.

Remove the semi colons before SMTP and smtp_port and set the SMTP to your smtp server and the port to your smtp port. Your settings should look as follows

SMTP = smtp.example.com
smtp_port = 25

Note: The SMTP settings can be gotten from your web hosting providers.
If the server requires authentication, then add the following lines.

auth_username = example_username@example.com
auth_password = example_password

Save the new changes. Restart Apache server.

mail($to_email,$subject,$message,$headers);
