PHP io_createNamespace函数代码示例

/**
 * Used to write out a DokuWiki page to file, and send IO_WIKIPAGE_WRITE events.

 * Action plugins are allowed to modify the page content in transit.
 * The file path should not be changed.
 * (The append parameter is set to false.)
 *
 * Event data:
 * $data[0]    The raw arguments for io_saveFile as an array.
 * $data[1]    ns: The colon separated namespace path minus the trailing page name. (false if root ns)
 * $data[2]    page_name: The wiki page name.
 * $data[3]    rev: The page revision, false for current wiki pages.
