PHP，HTML和字符编码

Question

I actually have a fairly simple question but I'm unable to find an answer anywhere. The PHP function html_entity_decode is supposed to "converts all HTML entities to their applicable characters from string ."

So, since Ω is the HTML encoding for the Greek captical letter Omega, I'd expect that echo html_entity_decode('Ω', ENT_COMPAT, 'UTF-8'); would output Ω. But instaid, it outputs some strange characters which my browser can't recongize. Why is this?

Thanks,

Martijn

Answer 1

When you convert entities into UTF-8 characters like your last parameter specifies, your output encoding must be UTF-8 as well. Otherwise, in a single-byte encoding like ISO-8859-1, you will see double-byte characters as two broken single ones.

Answer 2

It's works fine:

Make sure your webpage encoding is UTF-8

If you have different encoding on webpage change this:

html_entity_decode('Ω', ENT_COMPAT, 'UTF-8');
                                          ^^^^^

Answer 3

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

mysql_set_charset("utf8", $conn);
