How can PHP data from a form be properly sent and processed within a script?

When processing data from a form in PHP, you can use the $_POST superglobal to access the form data that has been submitted. You can then sanitize and validate the data before using it in your script to prevent security vulnerabilities. To properly send and process form data in PHP, you need to ensure that the form's method attribute is set to "post" and that the form fields have appropriate names. 

// Check if the form has been submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Access form data using the $_POST superglobal
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Sanitize and validate the form data
    $name = filter_var($name, FILTER_SANITIZE_STRING);
    $email = filter_var($email, FILTER_VALIDATE_EMAIL);
    
    // Process the form data
    // Your code here
}
