Question

Ok I need help with thisone:
I need something that matches backwards I think?
Like “match backwards from ‘.no’ until first space”
I need to replace some text with links.

See examples of what im trying to accomplish below:

blabla hello www.test.no bla => blabla hello <a href="www.test.no">www.test.no</a> bla

blabla hello test.no bla => blabla hello <a href="test.no">test.no</a> bla

blabla hello http://www.test.no bla => blabla hello <a href="http://www.test.no">http://www.test.no</a> bla

Anyone?

I still don’t understand what exactly you need, because your example is not explained very well, but here goes:

preg_replace('/[^ ]+\.no/', '<a href="$0">$0</a>', $your_text);

EDIT: there you go:

preg_replace("~(http://)?([^ ]+\.no)~", '<a href="http://$2">$2</a>', $your_text);
