返回数组速记属性的方法。 哪个PHP版本？

Question

At some point, I'm not sure when, the following shorthand property became available to reference an element in an array that became returned by a method:

echo $someObject->SomeMethod()['SomeElement'];

Where you append the element name after the method parentheses but before the semi-colon. What PHP version was this made available in?

Answer 1

Function array deferencing was available from PHP 5.4.0
