No, PHP doesn't have a magic shortcut syntax: just the basic $b = array_merge($a, [3, 4]);

It's part of PHP since December 2019 wiki.php.net/rfc/spread_operator_for_array

What about if I want to preserve keys? array_merge is not sufficient in this case.

@Facedownn did you try the code? array_merge preserves the keys. Or you meant something else?

Following example will not preserve keys causing 4 items on output, but I want only 2. array_merge(...[[2 => 'foo', 3 => 'bar'], [2 => 'foo', 3 => 'baz']]) I was looking for something like + (plus) operator for such case.

@Facedown please ask another question, this is not related to what you are asking.

Very nice! What's your source for this?

Found the proposal, looks like this isn't yet a thing, but is likely to be in 7.4: wiki.php.net/rfc/spread_operator_for_array

PHP supports the spread syntax for variadic functions .
In JavaScript, you can use the spread syntax to do this :
Parse error: syntax error, unexpected '...' (T_ELLIPSIS), expecting ']'
Is using the spread syntax this way not allowed in PHP? If so, is there an equally-as-elegant way to achieve the same effect?
The spread operator in the arrays RFC has been implemented in PHP 7.4:
Caveat: The unpacked array/Traversable can only have integer keys. For string keys array_merge() is still required.
Update: Spread Operator in Array Expression
An array pair prefixed by … will be expanded in places during array definition. Only arrays and objects who implement Traversable can be expanded.
It's possible to do the expansion multiple times, and unlike argument unpacking, … can be used anywhere. It's possible to add normal elements before or after the spread operator.
Spread operator works for both array syntax(array()) and short syntax([]).
It's also possible to unpack array returned by a function immediately.
<---------------End of Update-------------------->
First of all you are referencing the Variadic function with arrays in wrong sense.
You can create your own method for doing this, or you can better use array_merge as suggested by @Mark Baker in comment under your question.
If you still want to use spread operator / ... , you can implement something like this yourself.
But to me, doing it like this is stupidity. Because you still have to use something like array_merge. Even if a language implements this, behind the scene the language is using merge function which contains code for copying all the elements of two arrays into a single array.
I wrote this answer just because you asked way of doing this, and elegancy was your demand.
In PHP 7.4 you can now use Spread Operators in array expressions.
