Use simple CSS

p.a {
  white-space: nowrap;
}
<p class="a">
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
</p>

This works fine and also avoids multiple <br> tags following each other:

$string = '12
23
3
4
5
6';

var_dump(implode("\n<br>\n", preg_split('/(\r?\n)+/', $string)));

var_dump(preg_replace('/(\r?\n)+/', "\n<br>\n", $string));

Output:

string(38) "12
<br>
23
<br>
3
<br>
4
<br>
5
<br>
6"

string(38) "12
<br>
23
<br>
3
<br>
4
<br>
5
<br>
6"

preg_replace('/(\r)|(\n)/', '', $comment->text);

Output

"1 2"<br>"2 3"<br>"3"<br>"4"<br>"5"

You can just use this str_replace if you want to remove just spaces

$string = str_replace(' ', '', $string);

or if you want to remove all whitespeces use this

$string = preg_replace('/\s+/', '', $string);
