How Can I Send Emails Using PHP's mail() Function?

Sending Emails with PHP

In website development, the need to send emails is often encountered. PHP offers a straightforward method to achieve this using the mail() function.

Using the mail() Function

To send an email using PHP, you can utilize the mail() function. Below is an example:

$to      = '[email protected]';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: [email protected]'       . "\r\n" .
             'Reply-To: [email protected]' . "\r\n" .
             'X-Mailer: PHP/' . phpversion();

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

Requirements

It's crucial to note that the mail() function requires a properly configured SMTP server. This means your PHP installation must be configured with the correct SMTP settings. Additionally, the mail() function will not work on a local server. You will need a live web server to successfully send emails using PHP.
