pConfig can be used to create and manage hierarchical configuration files. The configuration is defined as a tree of unlimited depth on which the nodes may contain any type of values.

The class read and write the configuration to files. The class supports writing configuration files in a protected mode, which consists of generating a PHP script file that does not output anything if it is executed when it is directly accessible via the Web server.

This way it does not exposes the information stored in the configuration file.

The class also supports writing configuration files in a synchronized mode, on which each change to configuration tree is automatically saved to the configurator file. The class may also store comments to help other people understanding the data that is stored.

The generated configuration files are automatically indented according to the depth of the nodes.
