problem with php and character %

[Marcello2]

My php script works perfectly in the browser : all the % characters appear.
But in my script with actionscript, the % character does not load.
Must I do something special to encode in my php script or in my actionscript code ?

Thank you for your help.

That '%' symbold should be encoded as '%25' in PHP so that Flash can understand that as '%' symbol...

Thank you.
The problem is solved with
function envoi($var, $val){
echo "&".$var."=".urlencode(utf8_encode($val));
}
