smarty regex_replace [SOLVED]

[antosha]

Hi,
I have a little smarty question, hopefully someone can help me out : )

I have many strings that follow the following scheme :

Espiritu Santo, Vanuatu (SON)
Hamilton Island, Australia (HTI)
Bangkok, Thailand (BKK)
New York, NY, United States (NYC)
...


If {$mystring} is Bangkok, Thailand (BKK) how do I make the output to show :
BKK ?

If {$mystring} is New York, NY, United States (NYC) how do I make the output to show :
NYC?

... ,etc

I hope it's not too confusing  :)
Thanks

Have you tried substr?

{$mystring|substr:-4:3}

Code: Select all

{assign var='test' value='New York, NY, United States (NYC)'}
{$test|regex_replace:'/^.*\(|\)/':''}

Here are good links to try and learn some regex

Thanks a lot, both solutions work great
@ Nulling: I didn't know "substring" modifier existed in smarty, thanks.
@ Peciura: thanks for regex documentation, that will help me a lot.
