Question

Lets say I have the database table setup in this fashion,

ID | Name  | Area | Timestamp
---+-------+------+------------
1  | Hill  | 1    | 1293243080
2  | Sam   | 1    | 1293243084
3  | Joe   | 2    | 1293243087
4  | Bob   | 2    | 1293243089
5  | Matt  | 3    | 1293243091
6  | Billy | 3    | 1293243095

Then I wish to return the Name of the person with the largest Timestamp and with a certain Area number.

However, when I try to return for example the Name Bob I only get Billy because he has the largest Timestamp of everyone.

How can I get the php to select not only the person with the max Timestamp, but the person with a certain Area number also?

This is my code so far –

(I am looping it because I am displaying the name of the person with the largest Timestamp in each Area)

for ($t = 1; $t <= 3; $t++){
   $result = mysql_query("SELECT * FROM forum_posts WHERE Area='$t' AND Timestamp=(select max(Timestamp) from forum_posts)");

   while($row = mysql_fetch_array($result))
   {
       $post_name[$t]=$row['Name'];
   }
}

print_r ($post_name); 

What do you guys suggest I do?

Answer 1

   $result = mysql_query("SELECT * FROM forum_posts WHERE Area='$t' AND Timestamp=(select max(Timestamp) from forum_posts where Area='$t')");

a better option would be.

$result = mysql_query("SELECT * FROM forum_posts WHERE Area='$t' ORDER BY Timestamp DESC LIMIT 1");
