remove line breaks/text wrap

[Anon]

I'm going outta my head here...I need to replicate the functionality of the CR/LF removal tool in UltraEdit-32. Basically, what I'd like to do is remove any line breaks that occur at the end of a line that begins with text. If the line break is on a blank line by itself, I want to leave it there. This should serve to take multi-line paragraphs (currently terminated at the end of each line with a newline character) and turn them into one long line.

Any ideas? I'm sure a regexp will work, but I'm not sure exactly how.

try something like this:

ereg_replace ("\n", "", $body);

That won't work, because that will simply remove EVERY line break. Which I don't want to do.

The solution I've found is this. First, normalize the types of line breaks:

$body = ereg_replace("\r\n", "\n", $returndata);
$body = ereg_replace("\r", "\n", $returndata);

Then, put a text placeholder where there is a sequence of two linebreaks in a row:

$body = ereg_replace("\n\n", "foobar-doublespace-t1nman33", $returndata);

Next, remove all line breaks:

$body = ereg_replace("\n", " ", $returndata);

Finally, replace the text placeholder with a double linebreak wherever a paragraph should be:

$body = ereg_replace("foobar-doublespace-t1nman33", "\n\n", $returndata);
