If I do some filereadings before I access the mysql db
I get the following Warning:
Warning: 1 is not a MySQL link index in /usr/local/www/lugs/test/test.phtml on line 30

Every function for it self work perfectly.

And here the file:
<html>
<head></head>
<body>

<?
function read_file () {
  $filename = "/etc/hosts";
  if (is_readable($filename)) {
    $fp = fopen($filename, "r");
    if ($fp) {
      echo "<pre>\n";
      while (!feof($fp)) {
        $line = fgets($fp,1024);
        echo $line;
      }
      echo "</pre>\n";
    }
  } else {
    echo "<b>File $filename is not readable.</b>\n";
  }
}

function read_mysql () {
  $link_id = mysql_connect("localhost","root","");
  if (!$link_id) {
    exit;
  }
  $db_id = mysql_select_db("mysql",$link_id);
  if ($db_id) {
    $result_id = mysql_query("SELECT * FROM user",$db_id);
    if ($result_id) {
      $amount = mysql_num_rows($result_id);
      echo "Amount:$amount<p>\n";
      echo "<table border=1><tr><th>Host</th><th>User</th></tr>\n";
      for ($i=0;$i < $amount;$i++) {
        $host = mysql_result($result_id,$i,Host);
        $user = mysql_result($result_id,$i,User);
        echo "<tr><td>$host</td><td>$user</td></tr>\n";
      }
      echo "</table>\n";
    }
  }
  mysql_close($db_id);
}

read_file ();
read_mysql ();
?>
</body>
</html>

You are confusing $link_id and $db_id.  On line 30 you should be using $link_id instead of $db_id.
