[PHP] regular expressions question

[Simon Dedeyne]

I have a little question. I'm having some difficulty with regular
expressions:
 
here it is:
(this)example
should be output in an array
[0]=> this
[1]=> thisexample
 
I'm supposing this should be done with preg_grep, but I'm not really
familiar with some of it's syntax for the regular expression.
I could use some ideas,
 
 
cheers,
Simon
