PHP is a reflective programming language originally designed for producing dynamic web pages.[1] PHP is used mainly in server-side scripting, but can be used from a command line interface or in standalone graphical applications. Textual User Interfaces can also be created using ncurses.

mb_output_handler -- Callback function converts character encoding in output buffermb_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
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().
See also ob_start().
