What are some common issues with sending emails in PHP using a textarea form?

One common issue with sending emails in PHP using a textarea form is that the content of the textarea may contain special characters or HTML tags that can break the email formatting or cause security vulnerabilities. To solve this issue, you can use the `htmlspecialchars()` function to escape special characters and prevent HTML injection attacks. 

// Get the content of the textarea form field and sanitize it
$message = htmlspecialchars($_POST['message']);

// Send the email with the sanitized message
mail('recipient@example.com', 'Subject', $message);
