[SOLVED] really slow script

[thewooleymammoth]

ive got a page going that reads a file, if it exists and outputs it in a table, im trying to create a sort by catogory type link.

 

<?php
$pagename='Links';
include('tophalf.php');
?>
<?php 
if(isset($_COOKIE['auth'])) {  
echo "<table width='100%'>
      <tr align='center'>
        <td align='center'>
        Sort By
        </td>
      </tr>
      <tr align='center'>
        <td align='center'>
        <a href='links test.php?type=Comedy'>comedy</a>
        </td>
      </tr>
      <table>";
      $lastlink = 50;
  $type=strip_tags($_GET['type']);
  while($lastlink != 0){
    $filename = "links/".$lastlink.'.txt';
      
      if (is_readable($filename)){
        $openfile = fopen($filename, "r") or die('error1');;
        $content = fread($openfile, filesize($filename)) or die ('error2');
        $conexp = explode('|',$content);
        $date = date('F d Y H:i:s.', filemtime($filename));
        $user= $_COOKIE['auth'];
        $filenamecom="links/".$lastlink."com.txt";
        $color1='#4F4F4F';
        $color3='999999';
        $color2='#E5E5E5';
         if ($type == All || $type == $conexp[0]){
            echo "
            <table border='0' width='50%' bgcolor='$color1' cellpadding='5' cellspacing='2' align='center'>
                    <tr>                	
                      <td>insert advertisement<br></td>
                    </tr>
                    <tr>
                    <td align='left' width='100%'><h1 STYLE='font-family: Arial; font-size : 16pt; font-weight :bold;text-align : left; color :999999 ;margin:0;margin-left:2px;padding:0'>";
                  
                      if ($conexp[1] == 'safe'){echo "<img src='img/childsafe.gif' width='50' height='50'> ";}
                      else{}
                  
                  
                  
                      echo $conexp[0]."</span></td>
                    </tr>
                    <tr bgcolor=$color3> 
                      <td align='right' width='100%'>Added by <a href='member.php?user=".$conexp[2]."'>".$conexp[2]."</a><br>".$conexp[3]."</td>
                    </tr>
                    <tr bgcolor=$color3>
                      <td bgcolor=$color2><a href='".$conexp[4]."' target='_blank'>".$conexp[4]."</a>
                      <br>".$conexp[5]."</td>
                    </tr>
                    <tr align='center'>
                    <td><a href='linkcomments.php?lastlink=".$lastlink."'>View Comments</a></td>
                    </tr>
                    </table>
                    <br><br>
                    ";
                    fclose($filename);
                      $num=4;
                      $num2=$num+1;
                  $lastlink--;
         }else{}
      }else{
      $lastlink--;
      }
    }
}else{
echo 'Please Login to view Links';
}
?>
  <?php
  include('bottumhalf.php');
  ?>

 

the problem is that when get is set to all, it seems to have no problem but when its set to Comedy, it times out everytime, could someone please enlighten me on why its so slow and possibly how to fix it, thanks. an example of the file being displayed is as follows
