Are there specific PHP resources or documentation that can provide guidance on handling form data manipulation?

When handling form data manipulation in PHP, it is important to sanitize and validate user input to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One way to achieve this is by using PHP functions like `htmlspecialchars()` to sanitize user input and `filter_var()` to validate input against specific filters like email or URL. 

// Example of sanitizing and validating form data in PHP
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = htmlspecialchars($_POST["name"]);
    $email = filter_var($_POST["email"], FILTER_VALIDATE_EMAIL);
    
    // Further processing of sanitized and validated data
}
