deleting line separator

[Anon]

How can I delete the line seporator? For example, if I have a file that look like this (line separator is _):

HTML1
HTML2
HTML3_

and I wan to delete HTML2, how do I make the file like this:

HTML1
HTML3

instead of:

HTML1

HTML3_

I've tried ereg_replace("HTML2_","",$data); but that just makes my file look like this:

HTML1
HTML2
HTML3

Any ideas? Please?

If this is a singe string, you need to replace more than just the "" because there is also a newline character (\n) after the "";

I'm not sure I understand. In my file the HTML2 is a single line of HTML and I need to delete it with the line separator. If I undrestand correctly, to do that I need to put:

ereg_replace("HTML2_\n","","$data");

or what? I think I might have just confused myself more, lol, I'll shut up now and let you explain.
