regex

i can see the power of regular expressions but am having a bit of a battle
getting my head around them.

can anyone recommend some BASIC - tutorials for using regex

something like th idots guide :)
or even total idiots guide :)

somewhere that has some simple examples would be good toooo

any help would be fantastic

Chris

i just had a thought

is there any program that will create a regex
for example you select the criteria and it generate an appropriate regex

I'm sure there is, but whether you'd want to use one is a different matter.
Have you considered just messing around with regex after reading a tutorial?
Everyone I know who uses regex learned that way - if you become reliant on
software to write your code, you can find yourself in sticky situations ;)

i understand what u are saying and i agree - i would find it handy to be
able to create the regex BUt i would also work out how it does it and
eventually not use it

i have played arount with it but am still not quite understanding it - a
heap od examples would be great

like in one site i saw this and i thought it was good

/ # identify URLs within a text file
[^="] # do not match URLs in IMG tags like:
# <img src="http://mysite.com/mypic.png">
http|ftp|gopher # make sure we find a resource type
:\/\/ # ...needs to be followed by colon-slash-slash
[^ \n\r]+ # some stuff than space, newline, tab is in URL
(?=[\s\.,]) # assert: followed by whitespace/period/comma
/

More examples like thaT WOULD BE GOOD

Have you checked out PHP's manual? It has extensive documentation of PHP's
regex support. Once you're familiar with the terminology, it has everything
you need to know.

I checked out google for some more sites, and this one came up:

http://www.regular-expressions.info/

Let me know if it's not good ;)

I had exactly the same a few weeks ago =D

luckily I had lessons 'regular expressions' at my school a while ago
(eregi-style) of which i was very thankfull when I found out the power
of regex in php.

just start with some simple regular expressions, like converting \n to
<BR> (yes i know there is nl2br, but just as a practice). Then try to
strip all HTML tags out of a string. etc etc. start simple and make it
yourself more difficult every time.

If you really want to master regex en become a regex guru, I'd advise to
buy yourself a book on regular expressions.

Good luck with regex (they are fun to do =D)

I know you can do it tiger!

Chris,

www.regexbuddy.com has just what you're looking for.

I learned to compose regex's the "manual" way - which I agree is the best,
nevertheless, this tool still comes in handy sometimes.
