Remove Newline Character?

[LoneStarr]

I have a string that has a newline character and I want to print it out without the return.

str_replace will replace it with whatever I want, but it still breaks the string onto the next line. Is there no opposite of nl2br()?

Thanks!

I tried to write a quick script to see what the problem is, but I'm too tired I think.

Try using str_replace like you said, and replace the "\n"s with nothing.

$string = str_replace("\n"," ">",$string);

That'd work, surely.
I think there is an opposite to nl2br somewhere, or writing your own function for that isn't too tricky, but why do you need it?

a "br2nl" function would replace all "<br>"s in the string with "\n"s...

If this doesn't work, post some of the code up here so I can get an idea of what your trying to do.

Nice thing about this function is, it can be used for user input in textareas as well... since you never know if the contents will contain any sort of oddball combination of returns and newlines.

function ConvertNewLines($input,$towhat) {
	$input = trim($input);
	$inputARRAY = preg_split("/[\r\n]/",$input);

$cleanARRAY = array();//clear it out

for ($n=0; $n < count($inputARRAY); $n++) {
	$item = $inputARRAY[$n];
	if     ($item == '')      $ok = 0;
	elseif ($item == chr(13)) $ok = 0;
	elseif ($item == "\n")    $ok = 0;
	elseif ($item == "\r")    $ok = 0;
	elseif ($item == "\r\n")  $ok = 0;
	elseif ($item == "\n\r")  $ok = 0;
	elseif ($item == " ")     $ok = 0;
	else                      $ok = 1;
	if ($ok) {
		$cleanARRAY[] = $item;
	}
}

return trim(implode($towhat,$cleanARRAY));
}

That may be overkill btw 😃

Its just a useful function to alter up a bit for doing other things. I have an alternative version where a third param is entered to return the contents as comma delemited, an array, or a string without newlines. See, if a user intputs lines in a textarea field with returns to delimit each entry, then this function can be used to turn each line entry into a clean array, or comma seperated string.

So yeah ... take it as you please, but it does what you need, if not a bit overpowering.
