Flush the output buffer, return it as a string and turn off output buffering
string ob_get_flush ( void )

ob_get_flush() flushes the output buffer, return it as a string and turns off output buffering.

The output buffer must be started by ob_start() with PHP_OUTPUT_HANDLER_FLUSHABLE flag. Otherwise ob_get_flush() will not work.

Returns:

print_r(ob_list_handlers());
?>
