Does PHP have built-in data structures?

Question

I\'m looking at the PHP Manual, and I\'m not seeing a section on data structures that most languages have, such as lists and sets. Am I just blind or does PHP not have anything

Answer 1

Although this question is 8 years old I'm posting an answer because PHP 7 introduces an extension called ds providing specialized data structures as an alternative to the array.

The ds,

• uses the Ds\ namespace.
• has 3 interfaces namely,Collection, Sequence and Hashable
• has 8 classes namely, Vector, Deque,Queue, PriorityQueue, Map, Set, Stack, and Pair

For more information checkout the Manual and also This blog post has some awesome information including benchmarks.
