How can PHP be used to differentiate between different checkbox selections made by a user?

To differentiate between different checkbox selections made by a user in PHP, you can use the isset() function to check if a particular checkbox has been selected. You can assign unique values to each checkbox and then use conditional statements to perform different actions based on the selected checkboxes.

if(isset($_POST['checkbox1'])){
    // Checkbox 1 is selected
    // Perform specific action
}

if(isset($_POST['checkbox2'])){
    // Checkbox 2 is selected
    // Perform specific action
}

// HTML form with checkboxes
<form method="post">
    <input type="checkbox" name="checkbox1" value="1"> Checkbox 1
    <input type="checkbox" name="checkbox2" value="2"> Checkbox 2
    <input type="submit" value="Submit">
</form>
