Summary: preg_split and old version split
Status: Open

New Comment:
Three \s are needed to match one \. Could that at least be documented if it's
not wrong?
$text='AA\\nB and B\r';// contains \n and \r
print_r(preg_split('/\\\n|\\\r/', $text));
gives
Array
(
[0] => AA
[1] => B and B
[2] =>
)

Put simply, preg_split treats "\\" wrongly. It ought to search for an actual
"\" but never matches it.
