There is a php5-devel port which is currently at an earlier version  
(5.2.5RC2) than the php5 port (5.2.5) but it could possibly be  
updated to 5.3. I'm not sure if you can install php5-devel  
simultaneously with the php5 port, but if not, we could look into  
making it possible... But Jyrki may want to keep it for PHP 5.2.x  
release candidates. In which case, you may have to keep manually  
compiling as below.

Read the post-extract section of the mysql5 variant of the php5  
portfile to see how it copes with this. You just have to make a  
couple symlinks to make the layout match what php expects. You could:

cd /tmp
mkdir php5mysql5
ln -s /opt/local/lib/mysql5 php5mysql5/lib
ln -s /opt/local/include/mysql5 php5mysql5/include

Then use --with-mysql=/tmp/php5mysql5 in your php configure line  
instead. Then delete /tmp/php5mysql5 when you're done.

Apache cannot support multiple php modules simultaneously. But you  
may want to look into using the lighttpd web server with php accessed  
through fastcgi instead. I have in the past successfully had php4 and  
php5 running simultaneously under lighttpd. Assuming the php5 and  
php5-devel ports can be installed simultaneously (which again I'm not  
sure of) -- or if you build php 5.3 manually -- you should be able to  
get php 5.2 and 5.3 side by side as well. Here's an example from my  
lighttpd configuration file, which says to use php5 for all .php  
files, except if the URL contains "/php4/" in which case use php4 for  
all .php files. You could easily have it react to a different  
filename extension instead if you prefer. As you see lighttpd's  
configuration is quite different from Apache's and allows for some  
very interesting things, like this.


fastcgi.server = (".php" =>
	("localhost" =>
		(
			"socket" => "/tmp/lighttpd-" + var.datetime + "-php5-" + var.PID,
			"bin-path" => "/opt/local/bin/php-cgi",
			"broken-scriptfilename" => "enable",
			"allow-x-send-file" => "enable",
			"min-procs" => 2,
			"max-procs" => 2,
			"bin-environment" => (
				"PHP_FCGI_CHILDREN" => "4",
				"PHP_FCGI_MAX_REQUESTS" => "500"
			)
		)
	)
)

$HTTP["url"] =~ "/php4/" {
	fastcgi.server = (".php" =>
		("localhost" =>
			(
				"socket" => "/tmp/lighttpd-" + var.datetime + "-php4-" + var.PID,
				"bin-path" => "/opt/local/bin/php4-cgi",
				"broken-scriptfilename" => "enable",
				"allow-x-send-file" => "enable",
				"min-procs" => 2,
				"max-procs" => 2,
				"bin-environment" => (
					"PHP_FCGI_CHILDREN" => "4",
					"PHP_FCGI_MAX_REQUESTS" => "500"
				)
			)
		)
	)
}
