getting repository last change revisionfor a file

Hi all,
I'm migrating a repository from CVS to SVN. I want to (re)write a PHP
script which can list the files from a local copy that need to be updated
( a simple ' svn st -uv | grep '*' ') and print them on a web page. I
would also need for each file the last revision in which the item has last
changed on the local repository (the second revision column with svn st
-v), and the last revision in which the item has last changed on the
global repository. If i could get the number of commits per file between
local repository and the global one, it would be great.
I couldn't find a way to get such info with the svn client commands. I
thought of a way, wich is adding a property to the file each time I run a
commit (with the hooks). Every time I run 'svn ci', I could edit a
"last-changed" property to the current revision, for each file wich is
commited. I could also edit a "number-of-changes" property.
I hope there is a more simple way, I'd be glad to find about it.
