Both Ruby and Python are good, well-designed, modern, flexible and very good for productivity. Both of them can work for programming and web development, but it is difficult to award any of them better. So before answering such a question, one must suits it with personality/preferences and language strength. Better in preference and language, more suitable is that programming language.

1. PHP5 is an updated version of PHP and PHP4 is no longer developed. PHP5 has some of the advanced feature that makes it dominate over PHP4. Some of the features are:

Passed by Reference:  PHP5 promotes pass by reference for all objects, whereas in PHP4 all objects are passed by value.

Unified Constructors and Destructors: The user had to name the constructor as _construct() and destructors as _destruct(), in PHP5. This is unified.

Visibility: There are 3 levels of visibility in PHP5. They are:

Public- Methods are accessible to everyone including objects out of the class.

Private- Methods are accessible only within the class and not outside.

Protected- Methods are accessible within the class as well as the inherited class.

Exception: There are ‘exceptions’ introduced in PHP5, which makes it more powerful than PHP4.

2. Comparatively, PHP5 has better OOP (Object Oriented Programming), Closure, Namespace and Reflection; than PHP4 which is more a procedure language. PHP5 is a well suited programming language.

3. PHP5 incorporates static methods and properties. One can declare a class as Abstract too.

4. A special function called _autoload()  was introduced in PHP5. This function is automatically called when the user is trying to use a class which has not been defined yet.

5.  PHP5 introduces Interface. The interface must be defined in public only.

6. For interoperability with web service, PHP5 has introduced a brand new-built in SOAP Extension.

7. PHP4 was powered by Zend Engine 1.0 whereas PHP5 is powered by Zend Engine 2.0.

8. PHP5 has introduced some reserved words, new functions and a new error level defined as ‘E_STRICT’.

9. In PHP5, Streams have been very well improved, including the ability to access the low-level socket on Stream.

10. PHP5 includes some additional Object Oriented Programming concept than PHP4, like access specifier and inheritance. It also includes improved support of current content management system as well as reduced consumption of RAM.
