In what ways can HTML elements within PHP code impact the output of generated emails and how can developers address these issues?
HTML elements within PHP code can impact the output of generated emails by potentially breaking the email layout or causing rendering issues. To address this, developers can use PHP's strip_tags() function to remove any HTML tags before sending the email.
$email_content = "<p>Hello, this is a test email.</p>";
$email_content = strip_tags($email_content);
// Send email with $email_content
