<?
$txt = <<<eof
aaaaaaaaa
aaaaaaaaa
aaaaaaaaa
bbbbbbbb
bbbbbbbb
bbbbbbbb
eof;
$rep = preg_replace('/^(?s)(.*)(\r)?\n(\r)?\n/U','',$txt);
echo $rep."\n";

Note the optional \r and required \n. This is because, if the
input/output is ever touching a non-Windows machine, it won't use \r\n
for newlines - only \n.
