http_send_content_disposition

(PECL pecl_http >= 0.10.0)

http_send_content_disposition — Send Content-Disposition

bool http_send_content_disposition ( string $filename [, bool $inline = false ] )

Send the Content-Disposition. 当实际被发送的来自文件或类似东西的数据，要被客户端 /用户（例如，浏览器的“另存为...”弹出窗口）“保存”时，Content-Disposition 头是十分有用的。

Note: 此函数应与 http_send_data(), http_send_file() 和 http_send_stream() 一同使用。

filename: the file name the "Save as..." dialog should display
inline: if set to TRUE and the user agent knows how to handle the content type, it will probably not cause the popup window to be shown

成功时返回 TRUE，或者在失败时返回 FALSE.
