Hello -

What is the correct expression to remove any extra line breaks beyond
two in a string?

Sincerely,

There any may ways but I'd probably use something like:

$string = preg_replace('/(?<=\n)(\n?)\n*/s', "$1", $string);

The simpliest way is to replace linebreaks of three or more with two. Ugly
regexp:

preg_replace('/(?:(?:\r\n)|\r|\n){3,}/', "\n\n", $str);
