Application of PHP functions in sending emails
The functions provided in PHP simplify the email sending process, using these functions you can easily perform the following operations: Use the mail() function to send a basic email message, which requires specifying the recipient address, subject, and message body. Use the imap_open() and imap_mail() functions to send email using an IMAP connection, providing more advanced control. Use the imap_close() function to close the IMAP connection.

'X-Mailer: PHP/' . phpversion(); if (mail($to, $subject, $message, $headers)) { echo 'Email sent successfully'; } else { echo 'Error sending email'; } ?>

<?php $from = 'sender@example.com'; $to = 'receiver@example.com'; $subject = 'Subject'; $body = 'Message Body'; $imap = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'username', 'password'); if (!$imap) { echo 'Unable to connect to IMAP server'; exit; } imap_mail($to, $subject, $body, "From: {$from}\r\n"); imap_close($imap); echo 'Email sent successfully via IMAP'; ?>
