Beschreibung

The default MIME type begins with text/.
The mbstring.http_input setting is something other than pass.

Beispiele

Beispiel #1 mb_output_handler example


<?php
mb_http_output("UTF-8");
ob_start("mb_output_handler");
?>

Anmerkungen

Hinweis:
If you want to output binary data, such as an image, a Content-Type: header must be set using header before any binary data is sent to the client (e.g. header("Content-Type: image/png")). If Content-Type: header is sent, output character encoding conversion will not be performed.

Note that if 'Content-Type: text/*' is sent, the content body is regarded as text; conversion will take place.
