PHP offers the ability to create Shockwave Flash files via Paul
Haeberli's libswf module.
Note:
SWF support was added in PHP 4 RC2.
The libswf does not have support for Windows. The development of
that library has been stopped, and the source is not available
to port it to another systems.
For up to date SWF support take a look at the
MING functions.
Note:
This extension has been moved to the
» PECL repository and is no longer bundled with
PHP as of PHP 5.0.0.
