http string replace function

[wavesurf]

I have tried learning regular expressions, but have quite a lot left, and I need som urgent help:

I have a link in a text that need to be changed. The link is:
[example.no...]

which needs to be translated to:
[example.no...]

have the same problem with another link:
[example.no...]

needs to be translated to:
[example.no...]

Anyone know how this can be done? Thanks a lot.

What is the situation? In the situation you describe, I would not even bother with regex, just

$link = "http://www.example.no/slideshow.html?show_id=225";

$new_line = str_replace('slideshow.html?show_id=', 'services/slideshow.php?slideshowId=', $link);

Does that help or do you have many link patterns?
