An interesting article from IBM on using PHP with OpenLaszlo.

This “Spice up PHP applications with OpenLaszlo” tutorial series shows you how to use OpenLaszlo to create a more interactive interface for your PHP applications and how to use PHP to create more dynamic OpenLaszlo applications. It requires a basic understanding of — or willingness to learn — XML, JavaScript, and PHP. Each is well worth knowing for its own merits, plus they plug and play together nicely, since they’re all based on synergistic open standards.

On the server side, PHP is a widely supported scripting language that produces and reads XML data, interfacing easily with relational databases and other programs. PHP is great for implementing AJAX applications with service-oriented architectures. And it’s a smart choice for integrating Web services that use common Internet protocols, such as HTTP, XML-RPC, Simple Object Access Protocol (SOAP), and Representational State Transfer (REST).

On the client side, OpenLaszlo is an elegant XML-centric, JavaScript-based Web programming language. It’s designed for implementing interactive, media-rich, distributed, user-friendly interfaces to XML-based Web services. For programmers, the OpenLaszlo language is fun and feature-rich. For users, OpenLaszlo applications are richer and more responsive than conventional browser-based applications. (See Resources for available OpenLaszlo applications.)
