A PHP project in this documentation referes to a group of PHP files that are intended to be used together or are classified as files with related or similar functionality such as common code.

PHP files in this documentation are often referred to as Library Files because they can contain more than one class. The PHP files in the LJC PHP Projects are appended with "Lib" to indicate this potential relationship and in some cases to prevent a name conflict with the principle class in the file.

The LJC PHP projects attempt to define all related classes in the same PHP file. This makes it easier to include the classes in another PHP file. In some cases, related classes may be kept in one or more additional PHP files to make it easier to read and edit even though the classes are logically part of the associated parent file.

Files with related classes are kept together in the same project location. The exception is common code which is kept in a location accessible to all projects.

Library Files and Classes are prefixed with "LJC" to support uniqueness which helps to prevent duplicate name conflicts with other PHP files and classes.
