Are there any security concerns to consider when using PHP in an HTML page?

Yes, there are security concerns to consider when using PHP in an HTML page, such as the risk of code injection attacks. To mitigate this risk, it's important to properly sanitize user input and validate data before using it in PHP code. Example PHP code snippet for sanitizing user input: 

$user_input = $_POST['user_input']; // Assuming user input is received via POST method

$sanitized_input = htmlspecialchars(strip_tags(trim($user_input));

// Now you can safely use $sanitized_input in your PHP code
