HTTP Response

In addition to the native PHP features, there are also additional specific features to make it easier to handle HTTP response.

Set or remove response headers

The Response::header() is similar to native header() function, but he checks for issues in values. Example:


          use Inphinit\Http\Response;

          Response::header('Foo', 'bar');

Set or remove Content-Type header

Setting Content-Type as application/xml:


          use Inphinit\Http\Response;

          Response::type('application/xml');

Setting Content-Type as text/css with iso-8859-1 charset:


          use Inphinit\Http\Response;

          Response::type('text/csv', 'iso-8859-1');

Some types have shortcuts:

Usage	Equivalent
`Response::type('bson')`	`Response::type('application/bson')`
`Response::type('json')`	`Response::type('application/json')`
`Response::type('xml')`	`Response::type('application/xml')`
`Response::type('atom')`	`Response::type('application/atom+xml')`
`Response::type('rss')`	`Response::type('application/rss+xml')`

Force download

Forcing current page download:


          use Inphinit\Http\Response;

          Response::download('page.html');

Setting the Content-Length can help download managers provide an estimated download completion time, which can be done by setting the second parameter:


          use Inphinit\Http\Response;

          Response::download('report.pdf', 1000);

Status code

Get current response status code:


          use Inphinit\Http\Response;

          echo Response::status();

Set response status code:


          use Inphinit\Http\Response;

          Response::status(201);

Set response status code and return previous code:


          use Inphinit\Http\Response;

          $previous = Response::status(204);

          echo $previous;

It is possible to use the constants available in Inphinit\Http\Status (see: Response Codes):


          use Inphinit\Http\Response;
          use Inphinit\Http\Status;

          // Bad Request
          Response::status(Status::HTTP_BAD_REQUEST);

Set cache or no-cache headers

Define cache in seconds

Cache expires in 3600 seconds:


          use Inphinit\Http\Response;

          Response::cache(3600);

No cache

Use -1 for use no cache:


          use Inphinit\Http\Response;

          Response::cache(-1);

Set cache with English textual datetime descriptions

Cache expires 1 week:


          use Inphinit\Http\Response;

          Response::cache('+1 week');
