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 <A
HREF="function.header.html"
><B
CLASS="function"
>header()</B
></A
> 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.
</P
><P
> Note that if 'Content-Type: text/*' was send using
<A
HREF="function.header.html"
><B
CLASS="function"
>header()</B
></A
>, the sending data is regarded as text,
encoding conversion will be performed using character encoding
settings.
</P
><P
> 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 <A
