Sample script:
<html>
    <head>
        <title>Example</title>
    </head>
    <body>
    <table border=1>
<?php

$connect = mysql_connect( "localhost", "dbuser", "" );
$selectdb = mysql_select_db("mydatabase", $connect );
$result = mysql_query("SELECT * FROM mytable") or die ("Invalid Query");

while($row = mysql_fetch_row($result)) {
    echo "<tr>\n";
    $count = 0;
    while ($count++ < 10 ) {
        echo "  <td> &nbsp;$row[$count] </td>\n";
    }
    echo "</tr>\n";

}
mysql_free_result($result);

?>
    </table>
    </body>
</html>
