htmlspecialchars不转换

Question

I have this PHP code:

echo  htmlspecialchars("commen<p>commpen", ENT_QUOTES, 'UTF-8');

but it echos out this: commen<p>commpen

Unless I am wrong, that is not what it is meant to output. It should escape the <> to &lth; &gth;

The only way I have figured out to get around this is by using this header:

header('Content-type: text/plain; charset=utf-8'); 

Is there a way to do it without the header?

Answer 1

It is outputting <. But your browser is interpreting it as the entity it is and rendering <.

Seriously, try not encoding it, see what happens.
