[RESOLVED] function values

[NiChE]

Hi, i was wondering if somebody can help me to create a function to generate values with the following output:

0, 1, 2, 4, 8, 16, 32,... up until some number .

This may be a dumb question, but i don't know how to do this.

Thanks in advance.

generate an array of these numbers?It's fairly simple/short. So see below, if you have any questions be sure to ask!

function numberGenerator($limit){

$counter = 0; 
$array = array();

while($counter <= $limit){

	$array[] = $counter;

	if($counter > 0) $counter *= 2;
	else $counter = 1;

}

return $array;

}

print_r(numberGenerator(32));

I think the example could be simplified to:

function numberGenerator($limit) {
    $array = array();
    if ($limit >= 0) {
        $array[] = 0;
        for ($counter = 1; $counter <= $limit; $counter += $counter) {
            $array[] = $counter;
        }
    }
    return $array;
}
