在Codeigniter中使用for循环给出where条件,可以按照以下步骤进行操作: 1. 首先,确保已经安装并配置好了Codeigniter框架。 2. 在控制器或模型中,引入Codeigni...
如果是这样，您可以在进行查询时使用where_in()方法。这不是在查询完成后执行的操作，就像您在示例中所...

$sql="SELECT * FROM some_table WHERE id = ? AND status = ? AND author = ?";$db->query($sql,[3,'live','Rick']); 查询语句的问号会被方法第二个参数的数组顺次替换。 使用IN条件时,绑定用多维数组搞定集合: $sql="SELECT * FROM some_table WHERE id IN ? AND status = ? AND author ...
