• Hash tables VS associative arrays 5 answers

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?

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.
