Re: Perl extension for PHP

Hi, I used the last days to have a look at the ext/rpc stuff and it looks like a good way for writing a php-perl-Extension ;-) I also asked the author of the "perl-in-php" Extension if he wants to maintain his Extension any longer but he didn't answer, yet. during the next days/weeks/months I'll create a new Perl-Extension, based upon my old one and, maybe, parts of perl-in-php and the ext/rpc-skeleton. johannes On Saturday 03 May 2003 22:27, George Schlossnagle wrote: > It would be really nice to write this for php5 using the ext/rpc > sketelon.
