Multidimensional Array in PHP [With Examples] - Thus, an array with more than one dimension is called a PHP - multidimensional arrays. But to access an element in a multidimensional array in PHP, you require two indices for two-dimensional, three for three-dimensional array, and so on. When we talk about storing values in PHP, we talk about the word array.
When we talk about storing values in PHP, we talk about the word array. To store multiple values, there are two ways of carrying out the task. One way is to assign each value to a single variable, and the other, much more efficient way, is to assign multiple values to a single variable. That is what we call an array.
An array is a way to store multiple values in a single variable. Arrays, thus, form an important part of the programming communities go-to tools. Arrays can store both numeric as well as string values and can have multiple dimensions.
Thus, an array with more than one dimension is called a multidimensional array in PHP, which we’ll talk in great detail through hands-on examples later in the article.
To get a better sense of what an array is and its dimensions, let’s go through an example.
Suppose you go to a supermarket and buy a pack of biscuits. When you open the pack, the biscuits are lined up one after the other. This means they are arranged in a linear fashion, and hence, this is an example of a one-dimensional array.
Next, you think of buying a pack of assorted dry fruits. Now when you open the pack, there are slots both along the width and length of the box in which different dry fruits are kept. That forms an example of a two-dimensional array where the box represents the array, and the dry fruits in the slots make up the elements.
