为什么数组=== array在PHP中等于true？

Question

In php === is the identical comparison operator i.e. checks if two variables have equal values and are of the same type. But why array("asdf") === array("asdf") returns true? I guess both of these create new arrays with same contents(please correct me if I am wrong).

Answer 1

Simple answer: array("asdf") === array("asdf") returns true because the two arrays being compared:

1. have the same key/value pairs,
2. each of the same types, and
3. in the exact same order.

That's what array() === array() means.
