Esque tienes que concatenar fwrite con printf:
Código PHP:
fwrite($fgame, printf( "<html>
<head>
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=iso-8859-1\">
<meta name=\"GENERATOR\" content=\"Microsoft FrontPage 3.0\">
<title>title>
<base target=\"principal\">
</head>
<body>
<p align=\"center\">
<object id=\"FlashGame\" classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\"
codebase=\"http://download.macromedia.com/pub/shockwave/cabs/director/sw.cab#version=8,0,0,0\"
width=\"640\" height=\"480\">
<param name=\"SRC\" value=\"%s\">
<param name=\"AutoStart\" value=\"TRUE\">
<param name=\"Sound\" value=\"TRUE\">
<param name=\"logo\" value=\"TRUE\">
<param name=\"progress\" value=\"TRUE\">
<param name=\"PowerMenuEnabled\" value=\"TRUE\">
<param name=\"swModifyReport\" value=\"FALSE\">
<param name=\"swStretchStyle\" value=\"stage\">
<param name=\"swStretchHAlign\" value=\"center\">
<param name=\"swStretchVAlign\" value=\"center\"><embed src=\"%s\"
pluginspage=\"http://www.macromedia.com/shockwave/download/\" width=\"640\" height=\"480\"
class=\"FlashGame\">
</object>
</p></body>
</html>", $ressource ) );
Saludos.
