Set up a second Apache server with php5 loaded that listens to port 81 or some other port and point it at the same document_root. Then you can switch back and forth by just changing the port number in the URL. Or, if you, or your application, doesn't like having :81 in the url everywhere, you can set up a VirtualHost on your port 80 server just like you set up virtualhosts for anything else and in it add a ProxyPass to port 81. Like this: <VirtualHost *> ServerName name1.yourdomain.com DocumentRoot /var/www/html ... other standard config lines... </VirtualHost> <VirtualHost *> ServerName name2.yourdomain.com DocumentRoot /var/www/html ProxyPass / http://name2.yourdomain.com:81/ </VirtualHost> In your httpd81.conf or whatever you call it you have your regular VirtualHost block for the name2.yourdomain.com. The only real difference is that at the top you have a "Listen 81" line instead of "Listen 80". So now you can point your browser at http://name1.yourdomain.com and you get the PHP4 version of your site and if you go to http://name2.yourdomain.com you get the PHP5 version. I typically run at least 2 versions of PHP on my main server, sometimes more. You have to fiddle a bit with whatever mechanism you use to start and stop your server so it will start and stop the different versions. I tend to just cheat and copy my /etc/init.d/apache to /etc/init.d/apache81 and edit it appropriately changing the name of the conf file and the pid file. So I can start and stop the different versions manually. Building multiple versions of PHP isn't very hard either. The only real trick is to use the --prefix configure flag. Something like --prefix=/usr/local/php5. Then when you "make install" it will not overwrite any of your PHP4 stuff, with the one exception that it will try to modify your main httpd.conf by adding a LoadModule mod_php5.c /usr/libexec/apache/libphp5.so (or some similar path). Just go abd get rid of that line after your make install and move it to the httpd81.conf file. Also remember to add something like: --with-config-file-path=/etc/php5 So you can have separate php.ini files. Someone also mentioned the lack of decent opcode acceleration for PHP5. pecl/apc has come a long way over the last couple of months. Give it a try. I'd love to get some more feedback on it. To install it: pear install apc Will work if you are lucky. I tend to prefer doing it a bit more manually: cvs -d:pserver:cvsread@xxxxxxxxxxx:/repository login password: phpfi cvs -d:pserver:cvsread@xxxxxxxxxxx:/repository co pecl/apc cd pecl/apc phpize ./configure --enable-apc-mmap --with-apxs --with-php-config=/usr/local/php5/bin/php-config make install Then add this to you /etc/php5/php.ini file: extension=apc.so apc.enabled=1 apc.shm_segments=1 apc.optimization=0 apc.shm_size=32 apc.num_files_hint=1000 apc.mmap_file_mask=/tmp/apc.XXXXXX Obviously you can do a "make clean" and run ./configure again but this time point it at your php4 php-config file and build yourself an apc.so that you can use for your PHP 4 setup as well. Then copy the apc.php script that is included to your document_root and point your browser at it. You may want to password protect it. Or edit the top of the script where you can set a password. You will end up with something that looks like this: http://buzz.progphp.com/apc.php I don't really do Windows, but most of this will work on Windows as well (I think). You can find APC builds for Windows on http://snaps.php.net. But save yourself some headaches and grab a spare PC and install Linux (I prefer Debian, but it is a hassle to install for newcomers, the Ubuntu installer makes life easier), FreeBSD, or heck even the newly available OpenSolaris-x86 (I need to do that soon so I can play with the ultra-cool DTrace they have). Long rambling email, but hopefully it will inspire a few people to go push the edges a bit. Don't forget to report any bugs you find. For APC bugs, report them here: http://pecl.php.net/bugs/report.php?package=APC For APC docs, see the INSTALL file in the source, or go to: http://livedocs.phpdoc.info/index.php?l=en&q=ref.apc Which is mostly the same thing webified. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
