simpel vraagje over variabele en function
//show de width en height size
require ("images/swfheader.class.php") ;
$swf->loadswf($flashmovie) ;
$swf->showwidth();
$swf->showheight());
als ik dit in mijn script zet wordt er netjes de breedte en hoogte in pixels ge-echood.
maar hoe krijg ik die waarde nou in een variabele?
dus iets van $flashfilewidht=($swf->showwidth()); maar dat werkt dus niet.
Volgens mij moet $this->widht; aan een variabele toegekend worden die gereturned wordt ofzo in bijv.
function showwidth
