Display date only for the first post

I'm creating standard php loop using the while function to display latest articles on my site and I want to display each date only once at the top of the article. Something like this:

19 February

• Article title 1
• Article title 2
• Article title 3

18 February

• Article title 4
• Article title 5
• Article title 6
• Article title 7

17 February

• Article title 8
• Article title 9

and so on...

All the articles that is published on 18 February should be displayed under 18 February.

How can I do that using php? Can anyone please help?

Thanks in advance.

 

$last = ''; // This goes outside of your while loop
while($row = mysql_fetch_assoc($result)) {
    // If date isn't the same as the last one parsed
    if($row['date'] != $last) {
        // Assign it to the holding var
        $last = $row['date'];
        // And echo it out
        echo $last;
    }
}

You can also do it by using GROUP BY clause
