mysqli_stmt::__construct — Constructs a new mysqli_stmt object
This method constructs a new mysqli_stmt object.
注意:
In general, you should use either mysqli_prepare() or mysqli_stmt_init() to create a mysqli_stmt object, rather than directly instantiating the object with new mysqli_stmt. This method (and the ability to directly instantiate mysqli_stmt objects) may be deprecated and removed in the future.
