[Resolved] link a number from an array

[rikmoncur]

While learning php we do the bog-standard 'while' loop.
This one fills the screen with numbers - do it with green numbers on a black background and it looks like something from the Matrix movie...

But I was thinking, if the numbers were years then it's kinda like tree rings - you know the kinda thing where you've got a slice from an old tree trunk and there are labels to historical events pointing to the relevant ring?
Anyway, just for fun, I thought there might be a way to fill the screen with year numbers and link historical dates in the array to a popup or a layer etc.
Couldn't figure it out tho. Are individual numbers in an array gettable?

$number = 2007;
$current = 999;
while ($current < $number) {
++$current;
echo "$current, ";
}

Using array_key_exists(), you could do it something like this:

$events = array('1969' => 'First moon walk',
                '1911' => 'Robert Johnson born',
                '1981' => 'Britney Spears born',
                '2005' => 'France rejects E.U. Constitution',
                '2006' => 'E.U. dissolved');
$number = 2007; 
$current = 999; 
while ($current++ < $number) {
    if (array_key_exists($current, $events)) {
        echo '<b title="' . $events[$current] . '">' . $current . ', </b>';
    } else {
        echo $current . ', ';
    }
}
