PHP sending whitespace after headers?

[Harold Martin]

Hello-
I'm working on a simple script that does something like:
header('Content-type: text/directory');
echo "BEGIN:VCARD\r\ n";

However, PHP appears to send some additional whitespace after the
headers are sent (after the 200 OK message). I noticed this behavior
also occurs when no custom headers are sent. The problem here is the
some vCard readers will fail if the file begins with whitespace, so how
can I disable this extra whitespace sending in PHP?

Thanks-
Harold

I can think of two possibilities:

1) There *are* whitespaces in the script, maybe before a <?php tag.
2) You are including a UTF-8 encoded file with UTF-BOM (PHP doesn't handle
BOMs properly)

I double-checked, and this is definitely isn't the case.

I'm pretty certain this is not the case, but how would I check?

When you save a text file, the editor allows you to chose the encoding
(even Windows notepad). If it's ANSI, then it's not the case. If it's
UTF-8, then you must refer to your editor's configuration in order to know
if it's saving the BOM at the beginning of the file (or just save as ANSI
for troubleshooting purposes).

In any case, a small test case we can copy, paste and run, always helps.
