到期日期过后自动删除记录

Question

所以基本上，我的网站向用户显示一份工作清单，包括其详细信息，日期和到期日期。现在用户可以删除作业，我要添加的是自动删除。所以工作应该在到期日期过后自行删除，我不确定最好的方法。

这是将作业从数据库中显示出来的代码，以及一个删除语句，允许用户根据他们选择的内容手动删除作业。

function getJobs($conn)
{

 //$query = "SELECT * FROM jobs";
    $query = "SELECT * FROM job WHERE user_ID = :user_ID"; 
    $stmt = $conn->prepare($query);
    //$stmt->bindValue(':user_ID', $_SESSION["user_ID"]);
    $stmt->bindValue(':user_ID', $_SESSION['user_ID']);
    $stmt->execute();

    $workers=array();
    while($worker=$stmt->fetch(PDO::FETCH_OBJ))
    {
        $workers[]=$worker;
    }
    return $workers;
}

//INNER JOIN driver ON jobs.user_ID = driver.user_ID



function getAllJobs($conn)
{
 //$query = "SELECT * FROM jobs";
 $query = "SELECT * FROM job WHERE admin_id = :admin_id";
    $stmt = $conn->prepare($query);
    $stmt->bindValue(':admin_id', $_SESSION['user_ID']);
    $stmt->execute();
    $workers=array();
    while($worker=$stmt->fetch(PDO::FETCH_OBJ))
    {
        $workers[]=$worker;
    }
    return $workers;
}
