What is the best practice for passing checkbox values to the next page in PHP?

When passing checkbox values to the next page in PHP, the best practice is to use an array to store the selected checkbox values. This allows you to easily loop through the array and process each selected checkbox value on the next page. 

// Form with checkboxes
<form action="next_page.php" method="post">
    <input type="checkbox" name="checkbox_values[]" value="1"> Checkbox 1
    <input type="checkbox" name="checkbox_values[]" value="2"> Checkbox 2
    <input type="checkbox" name="checkbox_values[]" value="3"> Checkbox 3
    <input type="submit" value="Submit">
</form>

// next_page.php
<?php
if(isset($_POST['checkbox_values'])){
    $selected_checkboxes = $_POST['checkbox_values'];
    
    foreach($selected_checkboxes as $checkbox){
        echo "Checkbox value: " . $checkbox . "<br>";
    }
}
?>
