How can PHP developers troubleshoot and fix formatting errors in HTML emails?

Formatting errors in HTML emails can be troubleshooted and fixed by ensuring that the HTML code is properly structured and valid. PHP developers can use tools like HTML validators to check for any syntax errors or missing tags in the email template. Additionally, testing the email in different email clients can help identify any rendering issues that need to be addressed. 

// Example code to send an HTML email with proper formatting
$to = "recipient@example.com";
$subject = "Testing HTML email";
$message = "<html><body>";
$message .= "<h1>Hello!</h1>";
$message .= "<p>This is a test email with proper formatting.</p>";
$message .= "</body></html>";

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

// Send email
mail($to, $subject, $message, $headers);
