You could try something with a regular expression like:

    $new = ereg('[^{]*{([^}]*)}.*', '\\1', $oldstring);

which will match only the first word inside curly braces, or if
$oldstring contains multiple strings in curly braces, maybe:

    $newarray = split('}?[^{]*{', $oldstring . '{');

and then parse the array, and you'll probably want to toss [0], as it
will contain the data before the first left-curly-brace.  This method
needs a trailing left-curly-brace appended to $oldstring because the
regexp relies on it to mark the field.  You could alternately turn this
around as:

    $newarray = split('}[^{]*{?', '}' . $oldstring);

which is probably the cleanest way to do this, given the extent to which
you've described the data so far.  Note that split() will work just fine
on multi-line arrays, including fields split over multiple lines.  If
you want to process your data line-by-line, you'd need to wrap it.

The better you can predict the input data, the cleaner the code you can
use to parse it.

Learn the regexps.
