What are common pitfalls when using the Mail_Mime package from PEAR in PHP scripts?

One common pitfall when using the Mail_Mime package from PEAR in PHP scripts is forgetting to set the content type of the email. This can result in emails not being displayed correctly in the recipient's inbox. To solve this issue, make sure to set the content type to 'text/html' when creating the email.

// Set the content type to 'text/html'
$hdrs = array(
    'Content-Type' => 'text/html; charset=UTF-8'
);

// Create the Mail_Mime object
$mime = new Mail_mime("\n");

// Add HTML content to the email
$mime->setHTMLBody('<html><body><h1>Hello, World!</h1></body></html>');

// Build the email
$body = $mime->get();
$headers = $mime->headers($hdrs);

// Send the email
$mail = Mail::factory('mail');
$mail->send('recipient@example.com', $headers, $body);
