What are common issues with transferring specific characters in PHP form submissions?

One common issue with transferring specific characters in PHP form submissions is that special characters like "<" or ">" can be interpreted as HTML tags, potentially leading to security vulnerabilities like cross-site scripting (XSS) attacks. To prevent this, you can use the htmlspecialchars() function to encode these characters before displaying them on the webpage. 

$name = htmlspecialchars($_POST[&#039;name&#039;]);
$email = htmlspecialchars($_POST[&#039;email&#039;]);
$message = htmlspecialchars($_POST[&#039;message&#039;]);
