The default MIME type begins with text/. The mbstring.http_input setting is something other than pass. &reftitle.examples; ]]> &reftitle.notes; If you want to output binary data, such as an image, using PHP 4.3.0 or later, 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. If you want to output binary data, such as an image, using PHP 4.2.x or earlier, you must set output encoding to "pass" using mb_http_output. &reftitle.seealso; ob_start
