Question

So I have a query, and though my query can possibly return 20 results, I only want it to show the first 9 results. There is a dumb reason I’m not just limiting the query results to 9, for this purpose I need to know how to stop the while function if $i reaches 9.

Code is

    $i = 0;
    while($array = mysql_fetch_array($queryresults) && $i <= '9')
    {
               echo $array['id'];
               $i++;
    }

How do I get it to stop putting out more echoes after 9th result? Thank you!

Answer 1

Putting the limiting condition first will also make sure you only fetch 9 rows, not and 10 and one discard because && is called lazy (if the first part is false, it wont even look at the next part).

$i = 0;
while($i < 9 && $array = mysql_fetch_array($queryresults)){
    echo $array['id'];
    $i += 1;
}

or if you want to be fancy:

$i = 9;
while($i-- > 0 && $array = mysql_fetch_array($queryresults)){
    echo $array['id'];
}

But I find this error prone ..
