Grabing the 5 latest rows

[Lenard Redwood]

I am trying to create a PHP script that queries entries from a MySQL
table:

<?php
$user="myusername";
$password="mypassword";
$database="mydatabase";
mysql_connect(localhost,$user,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query = "SELECT ititle, inumber FROM nucleus_item";
$result = mysql_query($query);

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
echo "Name :{$row['ititle']} <br>" .
"Subject : {$row['inumber']} <br>";
}
mysql_close();
?>

What I'd like to do is to grab the 5 latest rows of the "inumber"
field. This field starts from 1 and currently ends at 2100 but everyday
there are new entries. So I think I should sort the table rows from the
greatest number to the lowest, and take only the 5 latest entries. I
didn't find on php.net how to do that. Any idea?
Thanks,

Lenard.

Be sure to set what field to order by, what order (DESC/ASC), and to
limit it to five, use LIMIT=5

Good luck!

Hi,

You don't find it at php.net because you should have searched your mysql
documentation. :-)
The keyword you are looking for is LIMIT

example:
SELECT firstname, lastname FROM tblusers ORDER BY lastname DESC LIMIT 10

Thanks, it's so simple... Problem is finding where in the docs... But
this worked very well, thanks.
