为什么回声后的这个标题不会产生错误？

Question

Why does this not throw an error:

echo "texto em cirílico sem conversão";
echo "русская слова";
header('Content-type: text/html; charset=utf-8');

Never mind the actual text, but I did echo some text, then sent a new header, which is obviously another header?

What am I missing here?

PS. I'm basing my thoughts on the general error which pops up when you try to send a header(location.... type of thing, but you had some errors before, and the compiler screamed about headers having already been sent.

I suppose you have output buffering enabled? Check your php.ini for output_buffering. If this is switched on, all printed text will first be cached in the output buffer before being sent to STDOUT.
