mysqli_stmt::close -- mysqli_stmt_close — Closes a prepared statement
面向对象风格
过程化风格
Closes a prepared statement. mysqli_stmt_close() also deallocates the statement handle. If the current statement has pending or unread results, this function cancels them so that the next query can be executed.
成功时返回 TRUE， 或者在失败时返回 FALSE。
if you are repeating an statement in an loop using bind_param and so on inside it for a larger operation. i thougt id would be good to clean it with stmt->close. but it broke always with an error after aprox. 250 operations . As i tried it with stmt->reset it worked for me.
