mysqli_stmt->close() — Closes a prepared statement
Procedural style:
Object oriented style (method):
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.
如果成功則回傳 TRUE,失敗則回傳 FALSE。
