In PHP, a multidimensional array is an array that contains other arrays within it. Each element of a multidimensional array can itself be an array, allowing for a hierarchical structure. This nesting of arrays enables the representation of complex data relationships and structures. The outer array contains the nested arrays as its elements, forming a multidimensional array. With multidimensional arrays, you can create data structures like tables, matrices, or trees to store and organize data in a structured manner.
