PHP Send Email with Attachments

 Dear All,

Here's an example code for attaching a file to an email in PHP using the built-in mail() function:

Php code

// recipient email address

$to = "recipient@test.com";

// email subject

$subject = "Test email with attachment";

// email message

$message = "This is a test email with attachment.";

// attachment file path

$file_path = "/path/to/attachment.pdf";

// attachment file name

$file_name = "attachment.pdf";

// read attachment file contents

$file_content = file_get_contents($file_path);

// encode attachment file contents in base64

$file_content = base64_encode($file_content);

// email headers

$headers = "MIME-Version: 1.0" . "\r\n";

$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

$headers .= "From: sender@example.com" . "\r\n";

$headers .= "Cc: cc@example.com" . "\r\n";

// email boundary

$boundary = "boundary_" . md5(uniqid(time()));

// email body

$body = "--$boundary\r\n";

$body .= "Content-Type: text/html; charset=UTF-8\r\n";

$body .= "\r\n";

$body .= "$message\r\n";

$body .= "--$boundary\r\n";

$body .= "Content-Type: application/pdf; name=\"$file_name\"\r\n";

$body .= "Content-Disposition: attachment; filename=\"$file_name\"\r\n";

$body .= "Content-Transfer-Encoding: base64\r\n";

$body .= "\r\n";

$body .= chunk_split($file_content) . "\r\n";

$body .= "--$boundary--";

// send email with attachment

if(mail($to, $subject, $body, $headers)) {

    echo "Email sent with attachment.";

} else {

    echo "Failed to send email with attachment.";

}

In the above code, I first specify the recipient email address, email subject, and email message. I also provide the file path and name of the file to be attached.

I then read the contents of the file and encode it in base64 format. I also specify the email headers, including the MIME version, content type, and sender and cc email addresses.

I specify the email boundary and create the email body, which includes the message and the attachment. The attachment is added as a separate section in the email body with the appropriate content type and encoding.

Finally, I use the mail() function to send the email with the attachment. If the email is sent successfully, I display a success message. Otherwise, we display an error message.
