ok, i'm really new to REGEX.

and i think i'm spending too many hours just staring on an expression.
now tell me as a newbie on REGEX how many hours should a newbie spend on
figuring out and starring on one expression alone?

i think i'm spending 5 hours and 10 hours just for one expression alone.
is this bad for me as a newbie to REGEX or it's a normal routine?

ok, to give you an idea on what i'm starring at.
i'm figuring out how to upload multiple files using array, foreach and regex as well.

or is it now imperative for me to buy the book of Jeffrey Friedl's "Mastering Regular ExpressioN"?

thank you very much in advance on your comments and suggestions.

Although it depends on the expression, 5 to 10 hours is way too much.

Regex has a very heavy "grasp factor": once you understand it, it becomes easy.

Depends on the expression--take a look at this. When you work with an expression deconstruct it piece by piece. If you're using preg, use the x modifier to document it:

 (\d+) # capture all digits
 a # then look for an 'a'...

That regex is useless, I guess:

once it clicks its sooooooo much easier..
i found a little book to regular expressions to give notes on whats what and such and that helped no end while i was writting it.. so have a look about..
