fwrite ødelægger kode

Hejsa harf et problem med noget php fwirte ødelægger kode?


Kode

$navn = $_REQUEST["navn"];
$code = $_REQUEST["code"];
$emne = $_REQUEST["emne"];
$minfil = $_REQUEST["minfil"];



// læser filer med indhold
$handle1 = fopen("indhold_top.php", "rb");
$top = stream_get_contents($handle1);
fclose($handle1);

$handle2 = fopen("indhold_bund.php", "rb");
$bund = stream_get_contents($handle2);
fclose($handle2);



//Opretter en fil med indholdet

$indhold = "$top $code $bund"; //Indhold vi gerne vil have ind i filen
$fil = fopen("$navn.php", "w"); //Åben filen
fwrite($fil, $indhold); //Skriv indholdet af $indhold ind i filen
fclose($fil); //Luk filen

Kode


$code indeholder denne linje


<object width="425" height="349"><param name="movie" value="http://www.youtube.com/v/GuMMfgWhm3g&hl=en&fs=1&rel=0&color1=0xe1600f&color2=0xfebd01&border=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/GuMMfgWhm3g&hl=en&fs=1&rel=0&color1=0xe1600f&color2=0xfebd01&border=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="349"></embed></object>

Men når filen er gemt ser den sådan ud

<center> <object width=\"425\" height=\"349\"><param name=\"movie\" value=\"http://www.youtube.com/v/GuMMfgWhm3g&hl=en&fs=1&rel=0&color1=0xe1600f&color2=0xfebd01&border=1\"></param><param name=\"allowFullScreen\" value=\"true\"></param><embed src=\"http://www.youtube.com/v/GuMMfgWhm3g&hl=en&fs=1&rel=0&color1=0xe1600f&color2=0xfebd01&border=1\" type=\"application/x-shockwave-flash\" allowfullscreen=\"true\" width=\"425\" height=\"349\"></embed></object> </center>


Hvad gør jeg forkert ?
