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.

Application of PHP functions in sending emails

PHP provides a series of functions that can be used to send emails easily. These functions are simple and effective to use, making email integration a breeze with any PHP application.

Required PHP modules

In order to use these functions, the following modules must be enabled in PHP:

  • php_openssl
  • php_imap

Commonly used PHP email functions

  • mail():This function is used to send Basic email message. It requires the recipient address, subject and message body as parameters.

    mail('receiver@example.com', 'Subject', 'Message Body');
    Copy after login
  • imap_open(): This function is used to open an IMAP connection, which allows you to communicate with the email server.

    $imap = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'username', 'password');
    Copy after login
  • imap_mail(): This function can be used to send email messages using an IMAP connection. It provides more advanced control than the mail() function.

    $from = 'sender@example.com';
    $to = 'receiver@example.com';
    $subject = 'Subject';
    $body = 'Message Body';
    imap_mail($to, $subject, $body, "From: {$from}\r\n");
    Copy after login
  • imap_close(): This function is used to close the IMAP connection.

    imap_close($imap);
    Copy after login

Practical case

Use mail() to send email

<?php

$to = 'receiver@example.com';
$subject = 'Subject';
$message = 'Message Body';

$headers = 'From: sender@example.com' . "\r\n" .
    'Reply-To: sender@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

if (mail($to, $subject, $message, $headers)) {
    echo 'Email sent successfully';
} else {
    echo 'Error sending email';
}

?>
Copy after login

Send email using IMAP

<?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';

?>
Copy after login
