How can PHP code be updated to be PHP5 compliant, especially in terms of handling form data?

To update PHP code to be PHP5 compliant, especially in terms of handling form data, you should ensure that the code uses the superglobal arrays like $_GET, $_POST, and $_REQUEST to access form data. Additionally, sanitize and validate user input to prevent security vulnerabilities. You can also consider using filter_input() function for input validation. 

// Example of updating PHP code to be PHP5 compliant in handling form data

// Access form data using superglobal arrays
$name = $_POST['name'];
$email = $_POST['email'];

// Sanitize and validate user input
$name = filter_var($name, FILTER_SANITIZE_STRING);
$email = filter_var($email, FILTER_VALIDATE_EMAIL);

// Process the form data
// Your code to handle the form data goes here
