The Adobe Acrobat PDF form below uses PHP and JavaScript to demonstrate SQL database and REST API interactions.
Acrobat PDF forms are very programmable, ideal for building and deploying custom calculation and interaction interfaces.

The form needs to be downloaded and opened with either AcrobatDC or the Acrobat Reader application to work correctly.
Accept the initial prompt to "trust" the document in order to connect to external data sources and test the form's functions.
