Thinking about it, this would probably be even better:
$string = preg_replace("/(\n|<br>){3,}/i", "\\1\\1\\1", $string);
This:
$string = "This is a
\n\n\n\n\n\n\n\n\n\n\ntest\nTesting\nTesting\n\n123<br><br><br><br><br><br><
br><br><br><br><br>Some more testing<br><br><br><br><br><br><br><br><br>And
a little
more<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br>Even more.";
Then outputs as this:
This is a <br />
<br />
<br />
test<br />
Testing<br />
Testing<br />
<br />
123<br><br><br>Some more testing<br><br><br>And a little
more<br><br><br>Even more.
when echo'd with nl2br()
As a side note, does anyone know what's with the <br> tag changing to <br
/>? That's the way I've always used the line break tag for wml pages, but
hadn't realised that it's being written that way for standard html now. Is
this a change in spec?
