Question

I’m setting up a system (PHP-based) that will let users instantly provision an SVN environment for use. It’s an internal project so the users will mostly be internal users.

I haven’t the foggiest idea where to even start. Are there SVN bindings for PHP, or am I going to have to use the svn console command?

Here’s one possibility. You’ll have a couple steps here. First, you need to create the svn repo in your PHP action script, maybe something like:

$name = $_REQUEST['name'];
// gonna need some sanity checking on $name here. no '..', no '/'s, etc
$cmd = 'svnadmin create ' . escapeshellarg('/var/svn/' . $name) . ' --fs-type fsfs';
exec('sudo ' . $cmd, $output, $exitValue);
if ($exitValue != 0) {
    // put the error message on the session, redirect out
}
$cmd = 'chown -R apache:apache ' . escapeshellarg('/var/svn/' . $name);
exec('sudo ' . $cmd, $output, $exitValue);
// error handling again

You’ll need to set up sudo to allow your web server to run that svnadmin command. Then you’ll need to drop in a new apache .conf snippet in /etc/httpd/conf.d:

<Location /$name>
   DAV svn
   SVNPath /var/svn/newproj
   #AuthType Basic
   #AuthName "SVN Repository"
   #AuthUserFile /var/svn/${name}.passwd
   #Require valid-user
</Location>

and restart Apache. Maybe create that newproj htpasswd file too for security. Be sure to check and sanitize all passed form values ($_REQUEST). Hope this gets you started.
