What is a multidimensional array in PHP?
- An array that stores values of the same data type.
- An array that can only have two dimensions.
- An array that contains other arrays as elements.
- An array that allows storage of different data types.
A multidimensional array in PHP is an array that contains other arrays as its elements. In other words, it is an array in which each element can itself be an array. This allows for a hierarchical structure, where values are organized into nested arrays. With multidimensional arrays, you can create structures like tables, matrices, or trees to represent complex data relationships. Each level of the array represents a dimension, and you can access the elements by specifying the index or key for each dimension.
