How can PHP foreach loop be utilized to handle variable values entered through checkboxes and text fields in a form?

When handling variable values entered through checkboxes and text fields in a form, you can use a PHP foreach loop to iterate through the values and process them accordingly. By looping through the $_POST array, you can access the values submitted from the form and perform actions based on the type of input (checkbox or text field). 

<?php
// Assuming form fields are named 'checkbox_values[]' and 'text_values[]'

// Handle checkbox values
if(isset($_POST['checkbox_values'])) {
    foreach($_POST['checkbox_values'] as $checkbox_value) {
        // Process each checkbox value
        echo "Checkbox value: " . $checkbox_value . "<br>";
    }
}

// Handle text field values
if(isset($_POST['text_values'])) {
    foreach($_POST['text_values'] as $text_value) {
        // Process each text field value
        echo "Text field value: " . $text_value . "<br>";
    }
}
?>
