本文介绍了如何使用PHP进行文件流操作，包括定位文件流位置的方法fseek()及其参数说明，获取流元数据的方式及返回值类型，并简述了数据库事务提交函数的相关用法。

    /**
     * Seek to a position in the stream.
     *
     * @see http://www.php.net/manual/en/function.fseek.php
     * @param int $offset Stream offset
     * @param int $whence Specifies how the cursor position will be calculated
     *                    based on the seek offset. Valid values are identical to the built-in
     *                    PHP $whence values for `fseek()`.  SEEK_SET: Set position equal to
     *                    offset bytes SEEK_CUR: Set position to current location plus offset
     *                    SEEK_END: Set position to end-of-stream plus offset.
     * @throws \RuntimeException on failure
     */

    /**
     * Get stream metadata as an associative array or retrieve a specific key.
     * The keys returned are identical to the keys returned from PHP's
     * stream_get_meta_data() function.
     *
     * @see http://php.net/manual/en/function.stream-get-meta-data.php
     * @param string $key specific metadata to retrieve
     * @return null|array|mixed Returns an associative array if no key is
     *                          provided. Returns a specific key value if a key is provided and the
     *                          value is found, or null if the key is not found.

    /**

	 * @link https://php.net/manual/en/mysqli.commit.php
	 * @param int $flags A bitmask of MYSQLI_TRANS_COR_* constants.
	 * @param string $name If provided then COMMIT $name is executed.
	 * @return bool true on success or false on failure.
	 * @since 5.5 Added flags and name parameters.
