Regex for matching CSS hex colors

Question

I\'m trying to write regex that extracts all hex colors from CSS code.

This is what I have now:

Code:

$css = <<

I'm not entirely sure if I got this right, but if you only want to match hex colors at the end of a CSS line:

preg_match_all('/#(?:[0-9a-fA-F]{6}|[0-9a-fA-F]{3})[\s;]*\n/',$css,$matches);

should work, all I did was add the optional \s; char group (optional semi-colon and spaces) and a line-break character (not optional) and it seemed to work.
And as @GolezTrol pointed out #FFF; is valid, too.

When tested on this:

$css = '/* Do not match me: #abcdefgh; I am longer than needed. */
.foo
{
    color: #CAB;
    background-color:#ababab;
}';
preg_match_all('/#(?:[0-9a-fA-F]{6}|[0-9a-fA-F]{3})[\s;]*\n/',$css,$matches);
var_dump($matches);

The output was:

array (array('#CAB;','#ababab;'))
