How can PHP be used to evaluate checkbox selections and execute functions accordingly?

To evaluate checkbox selections in PHP, you can use the isset() function to check if a checkbox has been selected. Based on the checkbox selection, you can then execute corresponding functions or perform specific actions. You can use conditional statements like if-else or switch case to handle different checkbox selections and execute the appropriate code.

<?php
if(isset($_POST['checkbox1'])){
    // Execute function for checkbox1 selection
}

if(isset($_POST['checkbox2'])){
    // Execute function for checkbox2 selection
}

if(isset($_POST['checkbox3'])){
    // Execute function for checkbox3 selection
}
?>
