如何从ruby脚本将$ _POST值传递给php脚本

Question

I need to run a cron job to add a svn repository using reposman.rb for Redmine. But we also have a php script (with an interface) that enable us to create repositories automaticly.

The php script receives a $_POST value, create the repos, sets permissions, assign some group for read and write access to the newly created repos.

My question is this:

1. how could I execute the php script, instead of the svnadmin create command in reposman.rb?
2. How can I give a $_POST parameter to the php script, so it could setup my svn repos correctly, using the php script.

Thanks

Edit: Here are some example of what both scripts do.

Ruby script:

...
// Add the repos
system "svnadmin create #{path}"
...

Php script:

// Receive the name of the repos to add
$dir= $_POST["dir"]; 
// Do all the stuff with the permissions
$cmd= "sudo /usr/local/bin/createsvnrepo $dir";
system("$cmd", $retval);
...

Since, @Richard Knop's comment helped me more than any answer, I will answer my own question to help others.

I used curb to send a post to the php script.

reposman.rb

...
# Added at start of file.
require 'rubygems'
require 'curb'
...

# Replace the creation of repos from 
module SCM
    module Subversion
        def self.create(path)
            system_or_raise "svnadmin create #{path}"
        end
    end
    ...
end

# to 
module SCM
    module Subversion
        def self.create(path)
            Curl::Easy.http_post(
                "http://example.com/customCreaterepos.php", # Url to the php script
                Curl::PostField.content('reposName', path)) # Index of php $_POST in script
        end
    end
    ...
end
