Due to incomplete APIs, HTTP - authentication and handling of POST requests has not been - implemented yet. - - SECURITY NOTE: PHP will happily run everything under the - web-root through the parser; so be careful what you put - there. - - Note that requests are served in a chroot'ed environment. - The initialization of PHP does not take place in the chroot'ed - environment, so that e.g. /usr/local/lib/php.ini is treated - as usual. - -REQUIRED DOWNLOADS - - 1.

PHP 4.0.x - - Download: - http://www.php.net/ - - Snapshots from CVS: - http://snaps.php.net/ - - -BUILD INSTRUCTIONS - - 1. Install TUX as outlined in the QuickStart text. - Create /tux-modules where modules will reside. - - 2. Prepare PHP - - $ cd php-* - $ ./configure \ - --with-tux=/tux-modules \ - <further PHP options> - # make install - - You can see the list of valid PHP options by executing - - $ ./configure --help - - 3. Touch a file in your web-root 'php4.tux'. This will - cause requests to '/php4.tux' to be redirected to the - userspace module php4.tux. - - 4. Start TUX with something like - - # tux -d -t 8 -r /www -m /tux-modules php4.tux - - (daemon mode, eight threads, web-root /www, modules in - /tux-modules, load php4.tux) - - BEFORE running this command, the kernel side of TUX has to - be properly setup. - - 5.
