hoi ik maak gebruik van een class die van een swf o.a. de breedte en hoogte in pixels weergeeft :

//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.
dan moet je de class gaan verbouwen want in dit stukje code word er niks geëchoed, post anders de class ff
ok, hier komtie. sry dat ik zo'n n00b ben maar ik kon ook niet snel iets vinden qua tutorial wat uitlegt hoe dat nou zit met o.a. $this->

Volgens mij moet $this->widht; aan een variabele toegekend worden die gereturned wordt ofzo in bijv.
function showwidth

Ik ben er al uit.

function showwidth() {

// FRAMESIZE

$flashfilewidth=$this->width;
return $flashfilewidth;


en in het script $flashfilewidth=$swf->showwidth();
