sFire PHP Framework
The sFire\HTTP\Response object can be used to add headers and files into the response for the client.
To add a single header to the response, you can call the addHeader method. This method accepts three parameters.The first parameter is the header you would like to set while the second parameter is the value of this header. The third parameter is an optional Integer which will set the HTTP status code.
Response :: addHeader(String $header, String $value, [Integer $code]);
Response :: addHeader('Keep-alive', 'timeout=15, max=100');
Response :: addHeader('Location', 'https://sfire.nl', 302);
To remove a single header you previously defined, you may use the removeHeader method. This method accepts one String parameter.
Response :: removeHeader('Keep-alive');
To remove all headers, you can use the removeHeaders method.
Response :: removeHeaders();
This will remove all previously defined headers from the response;
If you want to give the client a file, you may do so by calling the file method. This method accepts one parameter which is a sFire File object.
Response :: file(sFire\System\File $file);
use sFire\System\File;
use sFire\HTTP\Response;
$file = new File('foo.txt');
Response :: file($file);
To set a status code, you can use the setStatus method. This method accepts one parameter which is an Integer that is defined in the supported HTTP status codes which you can see below.
Response :: setStatus(404); //Similar to setting a header "HTTP/1.1 404 Not Found"
The server HTTP protocol version will be used. If non available, HTTP/1.0 will be used.
