if "abc" and "abc def" have to be linked with URL1 and URL2
then in the text:
"kjkhj abc lkjhsdf abc def ljh"
I want the output as
"kjkhj <a href=URL1>abc</a> lkjhsdf <a href=URL2>abc def</a> ljh"
instead of
"kjkhj <a href=URL1>abc</a> lkjhsdf <a href=URL2><a href=URL1>abc</a> def</a> ljh"
or
"kjkhj <a href=URL1>abc</a> lkjhsdf <a href=URL1>abc</a> def ljh"

How can I achieve this ?

Thanks in advance.

Here's what I would do...

Do the longer ones first, replacing the token "abc def" with some other value on a temporary basis. Then work your way down to the shorter ones. When you're done putting in the code to turn the item into a URL, replace the token strings with the original content.

In other words, sort your replacement strings by length:
abc def
abc

Next, replace abc def with ##TOKEN01##, and replace abc with ##TOKEN02##. You could use an array, where the original code is the index, as in
Code:
tokens['abc def'] = '##TOKEN01##'
tokens['abc'] = '##TOKEN02##'


Build your urls, and then replace every token with it's original language.

Since it's not the actual code, just an idea, I'll accept a picture of a BMW instead. Wink
