Note
Nota: If you want to output some binary data such as image from PHP script with PHP 4.3.0 or later, Content-Type: header must be send using header() before any binary data was send to client (e.g. header("Content-Type: image/png")). If Content-Type: header was send, output character encoding conversion will not be performed.
Note that if 'Content-Type: text/*' was send using header(), the sending data is regarded as text, encoding conversion will be performed using character encoding settings.
If you want to output some binary data such as image from PHP script with PHP 4.2.x or earlier, you must set output encoding to "pass" using mb_http_output().
