您可以遍歷車輛，並相應地打印出相應的項目（及其相應的檢查值），一舉完成。像這樣的東西會工作：

$vehicles = array('Bus', 'Van'); // You can add as many as you want! 

foreach($vehicles as $vehicle) { 
    // Should it be checked? 
    $checked = ''; 
    if(isset($_POST['car'])) { 
     if(in_array($vehicle,$_POST['car']) $checked="checked='checked'"; 
    } 

    // Add the element 
    echo "<input type='checkbox' name='car[]' value='{$vehicle}' {$checked}> 
     {$vehicle}"; 
}
