getStatus()

/**
 * This method is used to get the status of the promise.
 */
public function getStatus(): string;

This method allows you to take the status of a promise, check what condition they are in.

 - The status shows that promises are waiting to be fulfilled in the event loop.
 - The state of affairs shows that the promise has been fulfilled.
 - The situation shows that a promise is rejected when an event occurs.

Similarly we have functions like:

isPending()
isResolved()
isRejected()
