Here was my problem; I misunderstood how the "+" worked. It only applies to the last "\n", not both "n\n".

Strange, your code works for me:
[EMAIL PROTECTED]:~ > cat foo.php <?php $text = "foo\n\n\n\n\nbar"; echo "before:\n===\n$text\n===\n\n"; $text = preg_replace("/\n\n+/", "\n\n", $text); echo "after:\n===\n$text\n===\n\n"; ?> [EMAIL PROTECTED]:~ > php ./foo.php before: === foo
bar ===
after: === foo
bar ===
[EMAIL PROTECTED]:~ > php -v
