removing empty "lines" from string?

[Anon]

Hi all,

this time I have a rather dumb question but I'm kinda stuck:
I read a template-like file from mysql into a variable and replace certain tags. After replacing there are a lot of empty lines in the "file", any ideas how I can get rid of them?
$string = preg_replace("/^$/", "", $string);

and stuff won't work because there are no real "lines" in that string i guess...

Thanks in advance,

Dominique

maybe it is an idea to use chop?

tried stripping all the \n 's ?

you could try looking for [[:space:]] in your pattern and replacing it with null space "" that worked for me when I had that kinda problem

Hi Carl,
that's not what I want, I need the newlines, except for totally blanc lines...
[[:space:]] would only delete whitespace (which i need as well) but not empty lines, right?
