                               mb_output_handler

   (PHP 4 >= 4.0.6)
   mb_output_handler --  Callback function converts character encoding in
   output buffer

Description

   string mb_output_handler ( string contents, int status)

   mb_output_handler() is ob_start() callback function.
   mb_output_handler() converts characters in output buffer from internal
   character encoding to HTTP output character encoding.

   4.1.0 or later version, this handler adds charset HTTP header when
   following conditions are met:

     * Does not set Content-Type by header()
     * Default MIME type begins with text/
     * http_output setting is other than pass

   contents : Output buffer contents

   status : Output buffer status

   Return Value: String converted

   Example 1. mb_output_handler() example
   <?php
   mb_http_output("UTF-8");
   ob_start("mb_output_handler");
   ?>

     Note: 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().
