将HSL和/或RGB颜色从​​字符串转换为数组

Question

I need convert a HSL or RGB string color to array. I get by parameter something like:

$str = "rgb(40, 50, 60)"; // or "hsl(40, 50%, 60%)"

convert to:

array(40, 50, 60); // or array(50, "50%", "60%")

I preferer a solution using regex, I dont want to use split function ;-(

NOTE: I have a solution for RGB, but I dont work with HSL:

$rgb_color = sscanf($str, "rgb(%d, %d, %d)");

You just need to look for numbers and % symbol, \d in regex find you any digits. And preg_match_all php function return all of the matches not just the 1st one.

$matches = null;
$returnValue = preg_match_all('/([\d\%]+)/', 'hsl(40, 50%, 60%)', $matches);
var_dump($matches);
