PHP “backspace” character during output possible?

Question

I have a feeling the answer is \"it\'s not possible,\" but thought I\'d ask to satisfy my curiosity.

I have some code that\'s echoed where the \\n is unavoidable:

<

Answer 1

What about just replacing the "\n" by a white space (or just nothing, if you already have one space in your incoming string) ?

Like this, for instance :

$str = "Hello\nWorld!";
var_dump($str);

$str = str_replace("\n", ' ', $str);
var_dump($str);

The first output gives :

string 'Hello
World!' (length=12)

And the second one :

string 'HelloWorld!' (length=11)

Is that not enough ?
(Or maybe I don't understand the question well)
