    So I'm going to try this one:
    Code:
    '/\{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:

    PHP Code:
    $text '{abc def ghi}';
    if(
    preg_match('/^{[a-z ]*}$/'$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.
