After the download is complete, drag the downloaded .jar file to an open instance of Astah. A pop-up will appear asking you to confirm installation, choose [Yes]. If the pop-up below opens, restart Astah.
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].
A list of classes appears. Check the ones you’d like to export and click the [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.
