    mysqli_stmt_close

    (PHP 5, PHP 7, PHP 8)

    mysqli_stmt::close -- mysqli_stmt_close — Closes a prepared statement

    说明

    面向对象风格

    public mysqli_stmt::close(): true

    过程化风格

    mysqli_stmt_close(mysqli_stmt $statement): true

    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.

    参数

    statement

    仅以过程化样式：由 mysqli_stmt_init() 返回的 mysqli_stmt 对象。

    返回值

    总是返回 true。

    更新日志

    版本 说明
    8.0.0 This function now always returns true. Previously it returned false on failure.

    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.
