Rand array question

[scialom]

Hello,

I have this array:

$arr = array("1-3"=>2,"4-8"=>2,"9-10"=>1,"11-20"=>0);

I would like to get a random key where the value is greater than 0. So in this example I won't get the "11-20" key

is that possible?

Thanks!

yes it is very possible and there is a few different ways you can accomplish this but the easiest it just calling the key.

but here is something a little more dynamic....

foreach($arr as $key => $value)
{
    if(count($key) > 0)
    {
        echo $arr[$key];
    }
}

$positive = array_filter(
   $arr,
   create_function(
      '$var',
      'return $var > 0;'
   )
);
$randKey = array_rand($positive);
