How can I place text that relates to a foreach function, outside the loop?

I'm really unsure how to describe this, so please forgive me.

Basically, I'm reading from an XML, and then generating an IF statement that checks all records in the XML and if a condition matches, details about that record is displayed.

What I want to add, is a similar function but in reverse, but outside the foreach loop, so it's only displayed once.

foreach($xml as $Reader) { $items[] = $Reader; }
$items= array_filter($items, function($Reader) use ($exclude) {
    if($Reader->Picture == 'None' || in_array($Reader->Pin, $exclude)) { 
        return false;
    }   
        return true;
});
usort ($items, function($a, $b) { 
    return strcmp($a->Status,$b->Status); 
});
foreach($items as $Reader) {
    if($Reader->Status == 'Available' && !in_array($Reader->Pin, $exclude)) {
        echo "<a href='/details?Pin=".$Reader->Pin."'>".$Reader->Name ." (".$Reader->Pin.")</a> is available! ...&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
    }
}
if (!$items) { echo "Please check back in a moment when our readers will be available!"; }

So, in the XML file each Reader has a Status that can be one of three values: Available, Busy or Logged Off.

So what I'm doing, is for each record in the XML, checking if the Reader status is available.. and if so, echo the above line.

But I want to add in, that if NONE of the readers show as 'Available' to echo a single line that says 'Please check back in a moment'.

With the code above, ifthere are four readers online, but they're all busy.. nothing is displayed.

Any ideas?
