How can foreach be used to iterate through $_POST variables in PHP?

To iterate through $_POST variables in PHP using foreach, you can loop through the $_POST array and access each key-value pair. This allows you to easily access and process form data submitted via POST method. By using foreach, you can handle multiple form fields dynamically without explicitly naming each field. 

foreach ($_POST as $key => $value) {
    // Process each $_POST variable here
    echo "Key: " . $key . ", Value: " . $value . "<br>";
}
