I am running PHP 4.2.2, Apache 2.0.3.9, and MySQL 4.0.1-alpha-nt

I am using the following code to insert rows in to a html table:

######START CODE######
  db_connect();

  $result = mysql_query("SELECT * FROM db ORDER BY title");
  if ($result) {
    for($movies=0; $sts_tmp = mysql_fetch_row($result); ++$movies) {

      if($movies % 2 == 0) { $bgcolor="#CCCCCC"; }else{ $bgcolor="#DDDDDD"; }

      echo "      <TR>\n";
      for($x=0;$x<6;++$x)
        print "        <TD BGCOLOR='$bgcolor'>$sts_tmp[$x]</TD>\n";

      echo "        <TD BGCOLOR='$bgcolor'><INPUT TYPE='BUTTON' VALUE='Delete' ONCLICK=\"JavaScript:document.location='movie.php?action=delete&title=$sts_tmp[0]'\"></TD>\n" .
           "      </TR>\n\n";
    }

    echo "<TR><TD COLSPAN='7'><B>Total Movies: " . mysql_num_rows($result) . "</B></TD></TR>\n";
    mysql_free_result($result);
  }

  db_close();

######END CODE######

Most of the time the script runs fine, but every other third time or so extra garbage code appears in with the normal output.

Garbage Code:

      <TR>
        <TD BGCOLOR='#DDDDDD'>Mallrats</TD>
        <TD BGCOLOR='#DDDDDD'>0</TD>
        <TD BGCOLOR='#DDDDDD'>0</TD>
        <TD BGCOLOR='#DDDDDD'>0</TD>
??S???S?    BGCO @o?'#DDDDDD'>CD</TD>
        <TD BGCOLOR='#DDDDDD'></TD>
        <TD BGCOLOR='#DDDDDD'><INPUT TYPE='BUTTON' VALUE='Delete' ONCLICK='JavaScript:document.location="movie.php?action=delete&title=Mallrats"'></TD>
      </TR>
