A simple example of programming the Google Web API with PHP and the NuSOAP module.
PHP (http://www.php.net/), a recursive acronym for “PHP Hypertext Processing,” has seen wide use as the HTML-embedded scripting language for web development. Add to that the NuSOAP PHP module for creating and consuming SOAP-based web services (http://dietrich.ganx4.com/nusoap) and you’ve a powerful combination.
This hack illustrates basic use of PHP and NuSOAP in concert to interact with the Google Web API.
