Try this:

Code:

// you probably have a typo there '... is {constant1} and ...'
$subject = 'my name is {constant1} any I am looking for {constant2}';
$pattern = '#my name is (.+) any I am looking for (.+)#is';
$result = preg_match($pattern, $subject, $subpattern);
echo '<pre>'.print_r($subpattern, TRUE).'</pre>';

Sorry, I did not ask that correctly:


{constant1}, {constant2}, ... {constantN} are ment as placeholders in ANY string content, similar to a simplified template language. I am looking to grep all that tokens within the {...} with a regular expr.


Hope its clarified better, now

Okay, try this:

Code:

$subject = 'my name is {constant1} any I am looking for {constant2}';
$pattern = '#\{(.+)\}#isU';
$result = preg_match_all($pattern, $subject, $subpattern);
echo '<pre>'.print_r($subpattern[1], TRUE).'</pre>';

Regex is very powerful yet can be such a pain. For a really great reference site check out: http://www.regular-expressions.info/

Also I highly recommend having an editor that allows regex search/replace functions, as it is so much easier to paste example text into a text file and test inside the editor than it is to try running it through PHP first.
