PDOStatement :: bindParam data_type参数列表

Is there a list describing all of the data_type parameters you can use in PDOStatement::bindParam() ? If none, what do you commonly use, and for what type of field ?

是否有一个列表描述了您可以在PDOStatement :: bindParam()中使用的所有data_type参数?如果没有,你通常使用什么,以及什么类型的领域?

According to PHP manual: data_type Explicit data type for the parameter using the PDO::PARAM_* constants.

根据PHP手册:data_type使用PDO :: PARAM_ *常量的参数的显式数据类型。

I know about the PDO::PARAM_INT and PDO::PARAM_STR . I've heard of PDO::PARAM_LOB but I wasn't sure how and when to use that, though. (for date ?)

我知道PDO :: PARAM_INT和PDO :: PARAM_STR。我听说过PDO :: PARAM_LOB,但我不知道如何以及何时使用它。 (约会?)
