Comment

Buffers a header string to be sent
Returns the complete list of buffered headers

### Single header
e.g `header('Location', 'http://example.com');`

### Multiple headers
e.g `header(array('Location' => 'http://example.com', 'X-Extra' => 'My header'));`

### String header
e.g `header('WWW-Authenticate: Negotiate');`

### Array of string headers
e.g `header(array('WWW-Authenticate: Negotiate', 'Content-type: application/pdf'));`

Multiple calls for setting the same header name will have the same effect as setting the header once
with the last value sent for it
e.g `header('WWW-Authenticate: Negotiate'); header('WWW-Authenticate: Not-Negotiate');`
will have the same effect as only doing `header('WWW-Authenticate: Not-Negotiate');`

@param mixed $header. An array of header strings or a single header string
- an associative array of "header name" => "header value" is also accepted
- an array of string headers is also accepted
@param mixed $value. The header value.
@return array list of headers to be sent
