What are some common issues with handling POST variables in PHP5 compared to PHP4?

One common issue with handling POST variables in PHP5 compared to PHP4 is that the superglobal variable $_POST is no longer automatically registered as a global variable. To solve this, you can use the $_POST superglobal directly within the function or method where you need to access the POST variables. 

// PHP5 code to handle POST variables
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    // Use $username and $password as needed
}
