How can PHP foreach loops be effectively used to iterate through form data for processing?

When processing form data in PHP, using a foreach loop can be an effective way to iterate through the data and perform actions on each input field. By looping through the $_POST or $_GET array, you can access each form field and its corresponding value for processing. 

// Iterate through form data using foreach loop
foreach ($_POST as $key => $value) {
    // Process each form field here
    echo "Field: " . $key . ", Value: " . $value . "<br>";
}
