Launch Astah. If you find [PHP] – [Export PHP] under [Tools], that means the installation has completed successfully!
How to Use
Go to [Tools] – [PHP] – [Export PHP]
List of classes appears. Check ones you’d like to export and click [export] button.
Specify a target directly to export models to and click [OK].
If you’d like to see the PHP code real-time as you model, you can install “PHP Code View” plug-in which adds a window that shows the PHP code as you model. Download and install in the same way as you do with PHP export plugin.
