Is array a dynamic data structure?
A dynamic array is a random access, variable-size list data structure that allows elements to be added or removed. It is supplied with standard libraries in many modern programming languages. Dynamic arrays overcome a limit of static arrays, which have a fixed capacity that needs to be specified at allocation.

Just like arrays, retrieving the element at a given index takes O ( 1) O (1) O ( 1) time. Variable size. You can add as many items as you want, and the dynamic array will expand to hold them.
How to create a multi-dimensional array in PHP?
A multi-dimensional array each element in the main array can also be an array. And each element in the sub-array can be an array, and so on. Values in the multi-dimensional array are accessed using multiple index. In this example we create a two dimensional array to store marks of three students in three subjects −
