| Tóm tắt: | PHP has grown over the years and, thanks to its devotees, has continued to adopt the
functionality most preferred by its user base. By actually listening to the developers to help
guide PHP’s development path, the PHP creators have introduced some impressive function-
ality over the years. However, PHP 4, while a sound developmental language and tool, was
lacking on a few fronts. For instance, it had a means for developers to take an object-oriented
approach, but several key pieces of functionality were not implemented, such as exception
handling and session support (for objects).
PHP 5 has changed all that. No longer must developers write classes that are missing
functionality. Available to PHP is a full set of object-oriented development tools. Of particular
note in PHP 5 is the ability to protect class variables in several ways. In addition, inheritance
difficulties are now a thing of the past, and exception handling has become a nice way of tak-
ing care of pesky errors and validation. |
