How can PHP developers efficiently loop through and process form data submitted via POST?

To efficiently loop through and process form data submitted via POST in PHP, developers can use a foreach loop to iterate through the $_POST superglobal array. Within the loop, they can access the form field values using the keys of the array.

foreach ($_POST as $key => $value) {
    // Process form data here, using $key as the field name and $value as the field value
}
