While PHP and HTTP are outside the scope of GNU coreutils,
it's worth noting that the HTTP standard (which include POST
submissions) mandates "\r\n" (CR,LF) as line-endings in forms and in
headers, e.g.:

in HTTP headers:
https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html

In FORMS:
"Line breaks, as in multi-line text field values,
 are represented as CR LF pairs, i.e. `%0D%0A'."
from:  https://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.1

It doesn't, and the issue is still in "echo", not in "base64" :)
