PHP core_useragent::is_firefox方法代碼示例

/**
 * Handles the sending of file data to the user's browser, including support for
 * byteranges etc.
 *
 * The $options parameter supports the following keys:
 *  (string|null) preview - send the preview of the file (e.g. "thumb" for a thumbnail)
 *  (string|null) filename - overrides the implicit filename
 *  (bool) dontdie - return control to caller afterwards. this is not recommended and only used for cleanup tasks.
 *      if this is passed as true, ignore_user_abort is called.  if you don't want your processing to continue on cancel,
 *      you must detect this case when control is returned using connection_aborted. Please not that session is closed
 *      and should not be reopened.
 *
 * @category files
 * @param stored_file $stored_file local file object
 * @param int $lifetime Number of seconds before the file should expire from caches (null means $CFG->filelifetime)
 * @param int $filter 0 (default)=no filtering, 1=all files, 2=html files only
 * @param bool $forcedownload If true (default false), forces download of file rather than view in browser/plugin
 * @param array $options additional options affecting the file serving
 * @return null script execution stopped unless $options['dontdie'] is true
