What is the difference between Go arrays and PHP arrays?

There are some differences between Go arrays and PHP arrays in terms of how they are defined and used.

1. In Go, the elements in an array must be of the same type, while in PHP, an array can store elements of different types.
2. Size: When defining a Go array, the size of the array needs to be specified, while PHP arrays can dynamically increase or decrease elements.
3. Access: Go arrays use indexes to access elements, starting from 0; PHP arrays use associative arrays or indexed arrays to access elements.
4. Built-in functions: Go arrays do not have built-in array functions, so arrays need to be manipulated using loops and other operations. In contrast, PHP has a variety of built-in array functions for array manipulation.

In general, Go arrays are more strict and static, suitable for storing data with fixed sizes and types; while PHP arrays are more flexible and dynamic, suitable for handling data with uncertain sizes and types.
