How do I find the number of rows in a result set?

If is often useful to know how many rows are returned, and particularly when there may be no rows returned so that you can deal with that accordingly and tell the user to widen their search or try a different search, perhaps.

Here's how it is done, using the mysql_num_rows function which does what it says on the tin.

<?php
$query = "SELECT friends FROM listoffriends WHERE name = 'me'";
$doquery = mysql_query($query);

$myfriendnumber = mysql_num_rows($doquery);//returns integer value

if(!$myfriendnumber) { echo "Sorry, the person 'me' doesn't have any friends"; }
else { echo "The person 'me' has $myfriendnumber friends!"; }
?>
