greek url conversion and trim unwated numbers and symbols - php

Question

This problem is little complicated since i'm newbee to php encoding.
My site uses utf-8 encoding.
After a lot of tests, i found some solution. I use this kind of code:
function chr_conv($str)
{
$a=array with pattern('%CE%B2','%CE%B3','%CE%B4','%CE%B5' etc..);
$b=array with replacement characters(a,b,c,d, etc...);
return str_replace($a, $b2, $str);
}
function replace_old($str)
{
$a1 = array ('index.php','/http://' etc...);
$a2 = array with replacement characters('','' etc...);
return str_replace($a1, $a2, $str);
}
function sanitize($url)
{
$url= replace_old(replace_old($url));
$url = strtolower($url);
$url = preg_replace('/[0-9]/', '', $url);
$url = preg_replace('/[?]/', '', $url);
$url = substr($url,1);
return $url;
}
function wbz404_process404()
{
$options = wbz404_getOptions();
$urlRequest = $_SERVER['REQUEST_URI'];
$url = chr_conv($urlRequest);
$requestedURL = replace_old(replace_old($url));
$requestedURL .= wbz404_SortQuery($urlParts);
//Get URL data if it's already in our database
$redirect = wbz404_loadRedirectData($requestedURL);
echo sanitize($requestedURL);
echo "</br>";
echo $requestedURL;
echo "</br>";
}
When incoming url is:
/content.php?147-%CE%A8%CE%AC%CF%81%CE%B9-%CE%BC%CE%B5-%CF%80%CF%81%CE%AC%CF%83%CE%B1%28%CE%A7%CE%BF%CF%8D%CE%BC%CF%80%CE%BB%CE%B9%CE%BA%29";
I get:
/content.php?147-psari-me-prasa-choumplik
I want only:
/psari-me-prasa-choumplik
without the content.php?147- before URL.
BUT the most important problem is that I get ENDLESS LOOP instead of correct URL.
What am i doing wrong?
Have in mind that .htaccess solution won't work since i have a lighttpd server, not Apache.

If you need
I am assuming it's not always ?147- that you need to skip. But always after the first hyphen. In which case, before the echo add the following:
$requestedURL = substr($requestedURL, strrpos( $requestedURL , '-') +1 );
This will search for the position of the first hyphen and return that, add one so you skip the hyphen itself, and use that to cut the $requestedURL string up after the hyphen to the end of the string.
If it's always /content.php?127- then replace strrpos( $requestedURL , '-') +1 with the number 17.
