How to implement Hash tables, Maps in PHP

Question

I am looking forward to build an application in PHP. In the application I will need a hash table and maps. How to implement this in PHP, can we do this using an associative array? Is there any way to do this?

What do hash tables and maps provide that associative arrays don't? — Ignacio Vazquez-Abrams, Aug 17 '17 at 06:52
@IgnacioVazquez-Abrams, exactly, completely agree, php is very powerful like this. — SPlatten, Aug 17 '17 at 06:55
yeah right @IgnacioVazquez-Abrams but if we use hash tables we get built in functions for hashing but with associative arrays i dont know — , Aug 17 '17 at 07:00
Why do you think these "built in functions for hashing" are of any use to you? — Ignacio Vazquez-Abrams, Aug 17 '17 at 07:01

In the first paragraph on the array documentation, it says:

An array in PHP is actually an ordered map. A map is a type that associates values to keys. This type is optimized for several different uses; it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more. As array values can be other arrays, trees and multidimensional arrays are also possible.

So, you might be searching to do what's already done.
