Answer 1

PHP is a language. PHP 5 is a specific version of the language implementation, as opposed to 3, 4, or 6.

There are lots of alternatives to PHP. Almost any language can be used for web development via CGI, although it's more common to use a framework such as Django or Rails.

Answer 2

Note: I am assuming by 'PHP to PHP5' you mean from PHP4 to PHP5. PHP5 is not a different languages from PHP, it is simply a different version.

PHP4 to PHP5

Here is the main differences between PHP4 and PHP5.

http://www.php.net/manual/en/migration5.php

The specific OOP changes are featured in the Object Model

http://www.php.net/manual/en/migration5.oop.php

One of the places that page points that will give you the basics to how OOP works in PHP would be the Classes and Object reference page:

Learning PHP

To learn PHP, you can do a search on PHP and OOP on StackOverflow, and the first few results give you resources to do so:

http://stackoverflow.com/search?q=php+oop

If you want to skip clicking the link, you can just go to http://php.net, cause I guarentee that almost all of them point there. PHP has one of the best documentations out there, and it is extremely easy to use, and you will return to it very, very often.

For the record, the first result talks about how to learn object-oriented programming in php.
