Can I Attach Files to Emails Using PHP's mail() Function?

Adding Attachments to Emails with PHP Mail() Function

You desire to attach a PDF file to an email using the PHP mail() function, but you're wondering if it's feasible.

The Basic Code

Your provided code for sending an email looks like this:

$to = "xxx";
$subject = "Subject";
$message = 'Example message with <b>html</b>';
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: xxx <xxx>' . "\r\n";
mail($to, $subject, $message, $headers);

Limitations of PHP mail() Function

The mail() function in PHP has several limitations, one of which is that it doesn't natively support attaching files to emails. To overcome this, you could consider using an external library like PHPMailer.

Introducing PHPMailer

PHPMailer is a powerful and widely-used PHP library for sending emails, including those with attachments. Here's how to use it:

1. Download and Include PHPMailer

• Download PHPMailer from GitHub (link provided in the original response).
• Add its folder to your project.
• Include the main script file using require_once('path/to/file/class.phpmailer.php').

2. Send Email with Attachment

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

$email = new PHPMailer();
$email->setFrom('[email protected]', 'Your Name');
$email->Subject = 'Message Subject';
$email->Body = $bodytext;
$email->addAddress('[email protected]');

$file_to_attach = 'PATH_OF_YOUR_FILE_HERE';

$email->addAttachment($file_to_attach, 'NameOfFile.pdf');

$email->send();

Using $email->addAttachment(), you can effortlessly attach files to your emails.

Benefits of PHPMailer

• Ease of use with minimal coding required.
• Support for various email protocols (SMTP, POP3, IMAP).
• Ability to send multipart emails with attachments of various types.

In summary, while it's technically possible to attach files with mail(), it's highly recommended to use PHPMailer instead for its superior features and ease of use.
