What are some best practices for handling multiple checkbox selections in PHP forms for deletion operations?

When handling multiple checkbox selections in PHP forms for deletion operations, it is important to use an array for the checkbox inputs so that multiple selections can be captured. Then, iterate through the array to identify which checkboxes were selected for deletion. Finally, perform the deletion operation on the selected items. 

// HTML form with checkboxes
<form method="post" action="delete.php">
    <input type="checkbox" name="delete[]" value="1"> Item 1
    <input type="checkbox" name="delete[]" value="2"> Item 2
    <input type="checkbox" name="delete[]" value="3"> Item 3
    <input type="submit" value="Delete Selected Items">
</form>

// PHP code in delete.php
if(isset($_POST['delete'])) {
    foreach($_POST['delete'] as $item) {
        // Perform deletion operation on $item
    }
}
