How can the use of HTML emails impact the content-type and character encoding settings in a mail header when using PHP?

When sending HTML emails using PHP, it is important to set the content-type and character encoding in the mail header to ensure the email is displayed correctly in the recipient's inbox. This can be done by including the appropriate headers in the mail() function call. 

// Set content-type and character encoding
$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
mail($to, $subject, $message, $headers);
