Answer 1

function addNlToText($text) {
    $words = explode(' ', $text);
   $out = '';
   foreach ($words as $key => $value) {
       $out .= $value;
       if ($key % 2 === 0) {
           $out .= "\n";
       } else {
           $out .= ' ';
       }
   }
   return trim($out);
}

That’s dirty, but it does what you ask…

$text = 'Hello, how are you?';
addNlToText($text); // "Hello, how\nare you?"
$text = 'Hello';
addNlToText($text); // "Hello"
$text = 'Hello what is going on?';
addNlToText($text); // "Hello what\nis going\non?"
