Each class contains instance variables and instance methods. Some
of these variables and methods are available for customization, some are
internal to the classes themselves. All are documented, but tampering with
internal variables and methods is not supported. Internal interfaces are
subject to change without notice from one version of the library to
another.
This section covers PHPlib's core functionality. Classes are
presented in order of dependency, because the core structure is
easier understood in this order. You will need to understand the complete
core structure to successfully use all of PHPlib's features.
