how to make php_mapscript work with apache2 mpm worker as a dso?

[Liangxu Wang]

Hi all,
   I know how to make php_mapscript worked with php as cgi mode,but I
don't know how to make it worked as a dso with apache2_mpm_worker.
MapServer has a configure parameter:with-threads=linkopts,but what is
the linkopts? I have tried with with-threads and nothing appended it,
but the php_mapscript can't worked.
   So how can I make it work?
   Any help are appreciated.
   Best regards.

Sincerely yours,
Liangxu Wang
