    <?php 
       $username ="matt";
       $pass = "bs12kfj";
       $db = "mytest";
       $tbl = "test2";
       mysql_connect(localhost,$username,$pass);
       mysql_select_db($db) or die( "Unable to select database");
       $res = mysql_query("SELECT * FROM test2;");
       $num = mysql_numrows($res);
       echo "<table border='2'><tr>The Peeps</tr>"; 
       while ($r = mysql_fetch_array($res)) {
         echo "<tr>";
         foreach($r as $rs){
                     echo "<td>$rs</td>";
                     }
         echo "</tr>";
       }
       ?>

</body>

This code executes without error but the output contains a duplicate of every column of every row like so.

<table border='2'><tr>The Peeps</tr>
<tr><td>"matt"</td><td>"matt"</td><td>"phillips"</td><td>"phillips></td><td>"mathew.p@waburg.com"</td><td>"mathew.p@waburg.com"</td><td>20</td><td>20</td></tr><tr><td>"paul"</td><td>"paul"</td><td>"franklin"</td><td>"franklin"</td><td>"dude@live.com"</td><td>"dude@live.com"</td><td>30</td><td>30</td></tr><tr><td>"steve"</td><td>"steve"</td><td>"jobs"</td><td>"jobs"</td><td>"sjobs@apple.com"</td><td>"sjobs@apple.com"</td><td>23</td><td>23</td>

I don’t understand why each column is duplicated when there is only a single <td></td> tag in the echo statement.
I also checked the db and the table does not contain duplicate entries.

    You are probably fetching your MySQL result array in the default mode of MYSQL_BOTH.

    Try this:

    while ($r = mysql_fetch_array($res,MYSQL_ASSOC)) {
             echo "<tr>";
     foreach($r as $rs){
                 echo "<td>$rs</td>";
                 }
             echo "</tr>";
       }

    If you don’t specify the second argument to mysql_fetch_array(), then MYSQL_BOTH is used, and you end up with both an associative array index of values, and a numeric array index, like this:

    array(0 => 'field 1 val', 'field1_name'=> 'field 1 val',
      1 => 'field 2 val', 'field2_name'=> 'field 2 val', etc);

    Specifying either MYSQL_ASSOC or MYSQL_NUM will only retrieve either the associative values or the numerically indexed values respectively.
