The null coalescing operator (??) has been added as syntactic sugar for the common case of needing to use a ternary in conjunction with isset().
It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.
The spaceship operator is used for comparing two expressions. For example, $a <=> $b returns -1, 0 or 1 when $a is respectively less than, equal to, or greater than $b. Comparisons are performed according to PHP's usual type comparison rules.

The principle basically says, Class should depend on abstractions (e.g interface, abstract classes), not specific details (implementations). That means, You should let the caller create the dependencies instead of letting the class itself create the dependencies.
The principle states that no client should be forced to depend on methods that it doesn't use. A client should never be forced to implement an interface that it doesn't use or client shouldn't be forced to depend on methods that they don't use.
