PHP on mobile platform

sir

Since PHP is leading the web market, why not leading the mobile market too ?
Developing mobile application in PHP is possible. But you have to chose right framework.

Below you can find source code of Hello World application. With this tool you can develop multiplatform apps, because nowadays are clients for iPhone, iPod (also iPAD) and BlackBerry available.

PHP Code:
<?php
require "path/to/library/php-lib-1.1.php";

$ipf_form = new IPFForm();
$ipf_screen = $ipf_form->addScreen("screen", "Hello World Application");
$ipf_screen->addLabel("label", "Hello World!");
$ipf_form->render();
?>
