So I'm going to try this one:

'/\{SomeString [0-9a-zA-Z ]*\}/'

Err, who is "you" in "and I think you've applied the * wrongly"?

Anyway, as I already mentioned: you don't need to escape the { and } in your case.

Run this example:

$text = '{abc def ghi}';
if(preg_match('/^{[a-z ]*}$/', $text)) {
  echo "YES";
} else {
  echo "NO";
} 

It will print "YES": no need escaping them.

EDIT:

Ah, "you" was me. Yes, I misread your explanation. Well, what'd you know, I make my own point: no matter what people tell you on an online forum, always test it yourself.
