This is not a valid PHP statement.  It needs an assignment operator.  And /n is not the same as \n
$mystring str_replace("/n","",$mystring)

Try something more like this:
$mystring = str_replace("\n", NULL, $mystring);

Also, you might want to know about the context-aware constant, PHP_EOL.  It is the end-of-line character.

But all that aside, we cannot really tell what your data looks like or what you want it to look like.  If you want to post your string with the blank line, I will be glad to show you the code you need to remove the empty line.
This is what I use to remove all carriage returns in my input.

function data_correction($beta) {
	//this function is used to replace data copied and pasted from excel to make it into a useable format.
	$newstr = str_replace("\r\n", ",", $beta);
	return $newstr;

Open in new window

I paste information from excel and I don't like to seperate it into commas.  Hope that helps.
