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:

If you wanted to be able to do it for anything you could use the output buffer:

ob_start();

echo "Hello\n World";

$out = ob_get_contents();

ob_end_clear();
echo str_replace('\n', '', $out);

You could even use httaccess to append scripts containing this to any script called.

However, couldn't you just deal with it before it is set to stdout? Like

function print2($str){
    echo str_replace("\n", '', $str);
}
