Question

Im looping through some XML nodes, and say i have between 1 and 200 of these nodes.

How can i “randomly” select a maximum of 10 of these nodes. It has to be as most ten, but as few as 1.

This is what im working with now…

        $i = 0;
        foreach ($butters->users->user as $user) {
            if($i==10) break;
            $id = $user->id;
            $name = $user->screen_name;
            $profimg = $user->profile_image_url;
            echo "things";
            $i++;
        } 

The difficulty is that i don’t know how many i will have, but would like the pool from which i select my “random” 10 to be from the entirety of however many are present.

Answer 1

$randomPool = array_rand ( $butters->users->user, 10 );
