Versions of PHP and MySQL?

Can you tell what versions of PHP and MySQL Cs-Cart v.2 does need?

My provider has 4 versions of PHP and MySQL

Thank you

I was having a small issue and this is what I received from cs-cart.

As far as we know there are no any problems with PHP version 5.2.5. As for the version 5.2.6 there is one problem. Sometimes the full back up process of the database does not work properly. All other functionality work properly. We have our test CS-Carts installed on the PHP versions 5.2.6 and 5.2.5 and it works properly for us.

MySQL version is 5.0.32
