In this tutorial you will learn how to create indexed, associative, and multidimensional arrays in PHP as well as how to access their elements.

In PHP, arrays are extensively used for storing and manipulating data. An indexed array automatically assigns a numeric index starting from 0, while an associative array lets you use strings as keys.

By understanding the nuanced differences between indexed and associative arrays, you're well on your way to creating more efficient and readable code.
