How can the issue of receiving text/plain content as an attachment be avoided when sending HTML emails in PHP?
Issue: When sending HTML emails in PHP, some email clients may receive the email as a text/plain attachment instead of rendering the HTML content. This can be avoided by setting the appropriate headers in the email message to ensure that the HTML content is displayed correctly.
// Set the appropriate headers to send HTML emails
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
// Additional headers
$headers .= 'From: Your Name <youremail@example.com>' . "\r\n";
// Send the email with the correct headers
mail($to, $subject, $message, $headers);
