我收到一个语法错误，“第 38 行出现意外的 ':'”，我想不通：

public static function clearTasks($type){
    $con = taskDB::connectDB();

    switch ($type){
        /* line 38: */
        case: 'completed':
            $type='=1';
            break;
        case: 'failed':
            $type='=0';
            break;
        case: 'pending':
            $type='is null';
            break;
        case: 'all':
            $type='=1 or completed=0 or is null';
            break;
    }
    $result = $con->query("DELETE FROM taskage WHERE completed".$type);
    $con->close();  
}

谁能告诉我为什么会这样？谢谢！

没有:后case

case: 'completed':

应该

case 'completed':
