How can one ensure that only the field names are sorted and not the input values when sorting the POST array in PHP?

When sorting the POST array in PHP, you can ensure that only the field names are sorted by using the ksort() function, which sorts an array by keys. This will sort the field names alphabetically while keeping the input values associated with their respective keys. 

// Sort the POST array by keys (field names)
ksort($_POST);

// Loop through the sorted POST array
foreach ($_POST as $key => $value) {
    // Process each field name and input value
    echo $key . ": " . $value . "<br>";
}
