Introduction to PHP5
Luis Argerich
PHP5 is not yet official but the development versions are already usable (and unstable!) so we can start to learn and practice the new features of the upcoming version of PHP. In this article I will focus in three major new features of PHP5:.
  • The new object model
  • Exceptions
  • Namespaces
First of all a couple of disclaimers:
  • Some of the techniques described in this article can be done with PHP4, but are presented anyway to make the whole article more readable.
  • Some of the features described in this article may change in the final release of PHP5.
PHP5 has not been released yet and I don't know when that will be but you can already try and investigate the new features of the language by downloading and installing a PHP5 development version from http://snaps.php.net. There you will find Linux and Windows versions of PHP5 ready to be used. Installation proceeds as in any normal PHP distribution so go there and grab a brand new toy.
