final public setHeaderCallbacks(array $callbacks) : static
Sets an array of callbacks to be invoked just before headers are sent by the Response, replacing any existing callbacks.
This method is similar to
header_register_callback(),
except that multiple callbacks may be registered with the Response.
Each value in the $callbacks array is expected to be a callable with the
following signature:
function (Response $response) : void
The method is fluent, allowing you to chain a call to another Response method.
final public addHeaderCallback(callable $callback) : static
Appends one callback to the current array of header callbacks in the Response.
The $callback is expected to be a callable with the following signature:
function (Response $response) : void
The method is fluent, allowing you to chain a call to another Response method.
final public getHeaderCallbacks() : array
Returns the array of header callbacks in the Response.
final public hasHeaderCallbacks() : bool
Returns true if there are any header callbacks in the Response, false if not.
final public unsetHeaderCallbacks() : static
Removes all header callbacks from the Response.
The method is fluent, allowing you to chain a call to another Response method.
