What are the best practices for handling form data in PHP to ensure proper display of text values?

When handling form data in PHP, it is important to sanitize and validate user input to prevent security vulnerabilities and ensure proper display of text values. One common practice is to use the `htmlspecialchars()` function to escape special characters in the input data before displaying it on a webpage. This helps prevent XSS attacks and ensures that the text is displayed correctly.

// Sanitize and display form data
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = htmlspecialchars($_POST["name"]);
    $email = htmlspecialchars($_POST["email"]);

    echo "Name: " . $name . "<br>";
    echo "Email: " . $email . "<br>";
}
