How can dynamically generated checkbox names be effectively handled in PHP form submissions?

When dealing with dynamically generated checkbox names in PHP form submissions, it can be challenging to handle them because the number of checkboxes may vary. To effectively handle this, you can use array notation in the checkbox names so that they can be processed as an array in the PHP script. This way, you can loop through the array and handle each checkbox individually. 

// HTML form with dynamically generated checkbox names
<form method="post">
    <input type="checkbox" name="checkboxes[]" value="1"> Checkbox 1
    <input type="checkbox" name="checkboxes[]" value="2"> Checkbox 2
    <input type="checkbox" name="checkboxes[]" value="3"> Checkbox 3
    <input type="submit" name="submit" value="Submit">
</form>

// PHP script to handle form submission
if(isset($_POST['submit'])){
    if(isset($_POST['checkboxes'])){
        foreach($_POST['checkboxes'] as $checkbox){
            // Process each checkbox here
            echo "Checkbox ".$checkbox." is checked.<br>";
        }
    }
}
