[PHP] scan a text string to pick up certain words

2004-08-11 Thread Alex Shi 
Hi All,

I guess regex can do the trick but I don't know much about regex :((
Here is what I want:
Say a text string in which there're several words enclosed by {
and }, for example {hellow}. I need to pick up each of the words
like this and print them or do some processing one by one. 
Can any one please show me an example how to do this in PHP.
Thanks in advance!

Alex

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