SVN update made easy

PHP Subversion Updater

In our company we use Subversion for version control.

Using a GUI for Mac gives our more graphical team members easy access to common tasks, such as committing changed files to the repository.

However updating the working copy on a (test-) web server still requires knowlegde of a unix shell and having to log in and running it manually can be a full time position.

After doing some research I found the official PECL SVN bindings. These are still very experimental and a hussle to install.

So I decided to use the simplest solution that just executes a “svn up” on the server and does not require any server-side modification:

exec("svn up ".dirname(__FILE__), $out, $ret);

Which serves perfectly for this purpose.

Wrapping this line in a (30secs) self refreshing file makes sure the working copy stays updated.

And the best thing is:
it does not require anything, except installed svn binaries that are executable for the apache user and write access to the webroot.
