13.17 PHP-GTK

One advanced use of the CLI PHP interpreter is to use it along with the PHP-GTK functions, which let you write full-featured GUI applications. The existing version of PHP-GTK (1.0.0) works with PHP 4. A new version of PHP-GTK is in the works for PHP 5.

Example 13-21 uses PHP-GTK to display a window with a button in it.

Example 13-21. Displaying a button with PHP-GTK

$window =& new GtkWindow( );

$button =& new GTKButton('I am a button, please click me.');
$window->add($button);

$window->show_all( );

function shutdown( ) { gtk::main_quit( ); }
$window->connect('destroy','shutdown');

gtk::main( );

The window that Example 13-21 displays is shown in Figure 13-2.
