8 things you don't know about PHP 8

1 / Nullsafe operator
The most common error I have is...
"Trying to get property 'someProperty' of non-object"
Now it's solved with nullsafe operator
It reduces sooo much all these boilerplate checks!

2 / Named arguments
Ever had a hard time remembering the order of function arguments?
Don't bother anymore.
Just provide names of the arguments in any order. You can even skip arguments with a default value.
Awesome

3 / Match expression.
To reduce the boilerplate code in the switch statement, PHP 8 introduces the match expression.
No need for "break", many "case", "return".
Simple, self-explaining, easy-to-use

4 / Constructor property promotion
The common task of constructors is to pass arguments to class properties. Kind of initialization of the object.
Looks like a good candidate for removing boilerplate code.
So... now you can use constructor property promotion

5 / Mixed type
Yes, yes, we know that mixed type causes mixed feelings.
Some people argue that strict typing is better.
But we're in the PHP world and "mixed" is a new type.
PHP types:
- array
- bool
- callable
- int
- float
- null
- object
-resource
- string

6 / Throw expression
Throw is now not a statement but an expression, which allows us to use it in many new places.
A small, yet convenient feature

7 / Allowing ::class on objects
If we needed to get the class of an object, we used get_class($object).
Now it's possible to directly use $object::class.
Nice.

8 / New string functions
Few handful string functions were added:
str_contains()
str_starts_with()
str_ends_with()
Instead of ugly strpos()

As you can see, there are MANY new features in PHP 8.
I like pretty much null nullsafe operator & named arguments.
What's your favorite?
