How does implementing the POST/Redirect/GET pattern in PHP help in resolving issues related to resubmission of form data and browser compatibility?

Implementing the POST/Redirect/GET pattern in PHP helps in resolving issues related to resubmission of form data and browser compatibility by ensuring that form data is not resubmitted when the user refreshes the page, preventing duplicate form submissions and potential data corruption. 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    
    // Redirect to prevent form resubmission
    header("Location: ".$_SERVER['PHP_SELF']);
    exit();
}
