[RESOLVED] how to get special string from text

[cosbeta]

I have text like bellows:

$text ="demo demo {dd}hehe ahah {mm}and so on{like}";
how can I get the array $s from $text,whick $s should like this:

$S[0] = "dd";
$S[0] ="mm";
$S[0] = "like";

I can get $s by using str_split, does anyone have some simple way?

thanks!

preg_match_all('/(?<={)[^}]+(?=})/', $text, $matches);
$S = $matches[0];
print_r($S);

Or (possibly simpler)

preg_match_all('/{([^}]+)}/', $text, $matches); 
$S = $matches[1]; 
print_r($S);
