why does this code doesnt work ?????

I just cant figure out whats wrong with this code -

my friend made it to make the title to be attached along with the url to make it se friendly.The url comes like www.domain.com/page-title.html

here is the code and teh instructions that he told me to do-

http://muzica.x6.ro/melodia/strength-of-a-woman-3442.html

1) copy script melodia.php as melodia

2) add following script at the top

$infoArr = explode("/",$_SERVER["PATH_INFO"]);
$title = $infoArr[1];
$title = eregi_replace("\.html","",$title);

$titleArr = explode("-",$title);

$id = $titleArr[count($titleArr)-1];

3) add following code in .htaccess

AcceptPathInfo on // use only if apache 2

<Files melodia>
ForceType application/x-httpd-php
</Files>

but where do i attach this code and when i attach the respective code to .htaccess file the server shows error. I am really clueless...please help me.
