How can PHP developers handle sorting and manipulating checkbox values in a form submission for further processing?

When handling checkbox values in a form submission, PHP developers can use arrays to store the selected checkbox values. By naming the checkboxes as an array in the form, PHP can easily access and manipulate the values in the $_POST superglobal array. Developers can then loop through the array to sort and process the checkbox values as needed. 

// HTML form with checkboxes named as an array
<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 code to handle form submission
if(isset($_POST['submit'])){
    if(isset($_POST['checkboxes'])){
        $selectedCheckboxes = $_POST['checkboxes'];
        
        // Loop through the selected checkboxes
        foreach($selectedCheckboxes as $checkbox){
            // Process each checkbox value as needed
            echo "Selected checkbox: ".$checkbox."<br>";
        }
    }
}
