What debugging techniques can be applied to identify why the variable $empfaenger is not being populated with the selected recipients in the PHP code?

To identify why the variable $empfaenger is not being populated with the selected recipients in the PHP code, you can start by checking if the form data is being correctly submitted and if the variable is being properly assigned. Additionally, you can use debugging techniques such as printing out the values of variables involved in the process to trace where the issue might be occurring. 

// Check if form data is being correctly submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Assign selected recipients to $empfaenger
    $empfaenger = $_POST['recipients'];
    
    // Debugging: Print out the value of $empfaenger
    var_dump($empfaenger);
    
    // Further debugging steps can be added here to pinpoint the issue
}
