Question

Say i have a table called managers with 3 fields and i have 10 rows.

id        AgeGroup    name
1         a           1
2         a           2
3         a           3
4         b           4
5         b           5
6         c           6
7         d           7
8         d           8
9         d           9
10        e           10

code:

$con = mysql_connect("localhost","username","password");
if (!$con) {
    die('Could not connect: ' . mysql_error());
}

mysql_select_db("dbname", $con);
$query = "SELECT * FROM managers ORDER BY AgeGroup ASC"; 
$result = mysql_query($query) or die ("Error in query: $query. ".mysql_error());    

echo'<ul>';
if (mysql_num_rows($result)>0) {    
    while($row = mysql_fetch_array($result)) { 
        echo'<li>'.$row['AgeGroup'].'</li>';
    } 
} 
echo'</ul>';

I want to be able to echo the agegroup field but have no repeats.
Ie the output would be :

a
b 
c 
d 
e

any help would be appreciated

Add the GROUP BY clause in your query.

$query = "SELECT * FROM managers GROUP BY AgeGroup  ORDER BY AgeGroup ASC";
