PHP Help (Searching array then delete if found)

[Chris S]

I have the following code to look through my iTunes Library and compile some data for me.

<?php
$function = $_GET['function'];

$dbhost = 'localhost';
$dbusername = 'sterling';
$dbpasswd = '******;
$database_name = 'music';

$connection = mysql_pconnect("$dbhost","$dbusername","$dbpasswd")
    or die ("Couldn't connect to server.");

$db = mysql_select_db("$database_name", $connection)
    or die("Couldn't select database.");



$url1 = 'http://localhost';
$url2 = 'music';
$main_url = $url1.'/'.$url2;

$banned_urls = array("$url1", "$main_url", "$main_url.'/?C=D;O=A'", "$main_url.'/?C=M;O=A'", "$main_url.'/?C=S;O=A'", "$main_url.'/?C=D;O=A'", "$main_url.'/information.php'");

$links = GetInput("$main_url", '');

function GetInput($url) { 
   $handle=fopen($url, 'r');
   $contents = '';
   while (!feof($handle)) {
      $contents .= fread($handle, 8192);
   }
   fclose($handle);
   return $contents;
} 

function GetLinks($url, $filter) 
{
    $links = array();
    $match_domain='_[hH][tT][tT][pP]:\/\/(.*?)(/|$)_';
    preg_match($match_domain, $url, $res); 
    $domain=$res[1]; 
    if (!$domain) 
        return false; 
    if (!$input=GetInput($url)) 
        return false; 
    
    $lookfor='/<[aA]\s.*?[hH][rR][eE][fF]=[             "\']{0,}([-.,\%_\(\)|=~;+:\?\&\/a-zA-Z0-9]+)[ "\'>]/';
    preg_match_all($lookfor, $input, $data);
    while (list($k, $v)=each($data[1]))
    {
        // filter by
        if( strlen($filter) )
        {
            if( !strstr($v, $filter) )
            {
                continue;
            }    
        }
        if (stristr($v, 'javascript:'))
        { 
            // ignore - contains javascript
        } 
        elseif (stristr($v, '//')==$v) 
        { 
            $v='http:'.$v;
            $links[]=$v;
        } 
        elseif (stristr($v, 'http://')!=$v) 
        { 
            if (stristr($v, '/')!=$v)
                $sep='/';
            else
                $sep='';
            $v='http://'.$domain.$sep.$v; 
            $links[]=$v;
        }

    else
        $links[] = 'No Data';
    return $links; 
} 

if (($function) == 'artists'){

$artists = GetLinks("$main_url", '');

Please choose an option<br>

Basically what I am trying to do is search $albums and see if there are some links in there. If there are (i know there will be) delete them. The one important thing is that I atleast get rid of the http://localhost because that will make it search the music directory over and over.

Also, How do I remove %20 from the url. I tried

   $search = "%20";
   $replace = " ";
 $albums = preg_replace($search, $replace, $artist_album); 

but i get

Warning: preg_replace() [function.preg-replace]: No ending delimiter '%' found in G:\wamp\www\music\information.php on line 111

and line 111 is the $abbums = preg_replace..... code.

Anyways if you can help me with at least one of the problems that would be great.
