Installation Instructions

Download the deb file for your version of Ubuntu above and double click this file when downloaded.

Once installed you will need to edit your php.ini file to get it to work.

$ sudo gedit /etc/php5/cli/php.ini

In the Dynamic Extensions part of the file add the line extension=php_gtk2.so

;
; If you wish to have an extension loaded automatically, use the following
; syntax:
;
;   extension=modulename.extension
;
; For example, on Windows:
;
;   extension=msql.dll
;
; ... or under UNIX:
;
;   extension=msql.so
;
; Note that it should be the name of the module only; no directory information
; needs to go here.  Specify the location of the extension with the
; extension_dir directive above.

extension=php_gtk2.so

You may wish to do a simple test to make sure all is working (taken from http://gtk.php.net/manual/en/tutorials.helloworld.php).

<?php
if (!class_exists('gtk')) {
 die("Please load the php-gtk2 module in your php.ini\r\n");
}

$wnd = new GtkWindow();
$wnd->set_title('Hello world');
$wnd->connect_simple('destroy', array('gtk', 'main_quit'));

$lblHello = new GtkLabel("Just wanted to say\r\n'Hello world!'");
$wnd->add($lblHello);

$wnd->show_all();
Gtk::main();
?>
