This is how I solved it:

<?
# read stylesheets from a file
$filen=join("", file($stylesheetfile));

# remove everything between /* and */
$filen = preg_replace("!/\*.*?\*/!ms", "", $filen);

# remove whitespaces after semicolons
$filen = preg_replace("/;\s+/m", "; ", $filen);

# remove whitespaces after {
$filen = preg_replace("/{\s+/m", "{ ", $filen);

# remove whitespace before {
$filen = preg_replace("/\s+{/m", " {", $filen);

# replace several newlines with one
$filen = preg_replace("/\n{2,}/m", "\n", $filen);

# Leading whitespace
$filen = preg_replace("/^\s*/m", "", $filen);

# Multiple whitespaces to one
$filen = preg_replace("/ +/m", " ", $filen);

# Split every row and put in array as:
# filestylearray[selector][attribute]="value";

foreach(split("\n", $filen) as $line){
preg_match("/^(.*){\s*(.*)\s*;\s*}\s*$/", $line, $m);
foreach(split(";",$m[2]) as $attribline){
$a=split(":", trim($attribline));
$stylearray[strtolower(trim($m[1]))][trim($a[0])]=trim("$a[1]");
}
}

?>

It doesn't sort it like you want it to, but it can be tweaked.

Your example would end up in:

Array
(
[h1] => Array
(
[font-family] => Verdana, Arial, Helvetica, sans-serif
[font-size] => 16px
[font-weight] => bold
[color] => #003399
)

)
