    I never used PHP3. PHP 4 is more of procedural, PHP 5 is OOP based. That's in a nutshell.

    If you want more details, go to PHP 5 change log at http://www.php.net/ChangeLog-5.php, and search for Version 5.0.0 Beta 1. It will give you all the differences.

    Bottom line: More speed, better performance, more modularization, better extensions, SQLite, etc.,

    1)
    php3-functionalities are addes
    php4-zend engine is added
    php5-oops concepts are added

    2)
    PHP 3 is useless compared to 4 and 5.
    PHP 4 is used mostly by programmers who are hosted under it and don't have a say in the matter (and, it's actually faster, but not by much).
    PHP 5 is the recommended choice. It has true OOP.

    in PHP3 there is no superglobal variables. it introduce in PHP4.
    PHP5 introduce :

    * The new language features
    * News concerning PHP extensions
    * Other noteworthy changes to PHP’s latest version

    it also introduce some new tags like preg_match().

    All three have different advantages but PHP 5 is running faster and it is much easier to handle for us.
