Php :: Place Variables In HTML Swf Wrapper?

Can you place php varibles in the html wrapper for a swf, that could be read into the swf when it loads?Perhaps using a param?

$myVariable = "$var1,$var2,$var3";

like this with php in the html?

<param name=FlashVars value="$myVariable" />

or perhaps ?

<param name=FlashVars value="myVariable=$myVariable" />

Then perhaps in the swf with as3 using something like this?

var myloader:URLLoader = new URLLoader()
myloader.load(new URLRequest(this.root.loaderInfo).parameters))
myloader.addEventListener(Event.COMPLETE, onLoaded)

[code]...

Unsure how to access it using the correct path to the param and then how to get the php variable $myVariable into myloader.data?
