and sorts the result by the "Age" column:
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
$result = mysql_query("SELECT * FROM Persons ORDER BY age");
while($row = mysql_fetch_array($result))
{
echo $row['FirstName'];
echo " " . $row['LastName'];
echo " " . $row['Age'];
echo "<br />";
}
mysql_close($con);
?>

Order by Two Columns
It is also possible to order by more than one column. When ordering by more than one column, the second column is only used if
the values in the first column are equal:
SELECT column_name(s)
FROM table_name
