Object extraction

PHP did not have object-oriented capabilities until version 4, while subsequent versions maintained backwards compatibility. This means that PHP applications can be written in a completely procedural manner.

nTile PtoJ translates PHP applications making full use of Java™'s object-oriented character. Each PHP file is transformed into a class, while each explicitly declared PHP class is moved into its own file.

Variables used throughout the application are explicitly declared in either:

• a special class that encompasses global variables
• a regular class, generated from PHP code
• a function, if the variable is local

The emulation of the PHP runtime is partitioned into specialized classes, for better encapsulation and maintenance.
