?>Зауваження:
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.
