1. Merging Arrays The Array_merge () function merges the arrays together to return an array of unions. The resulting array starts with the first input array parameter, forcing it sequentially in the order in which the array parameters appear later.

An array is a variable that can store a group or a series of values. * Arrays are a basic data type. Array functions can also implement data structures such as stacks and queues. Subscript: the identifier of an array, that is, the code of a string

In java, the index of an array must be a number, and the number of arrays must be determined when the array is declared. Php is more flexible. indexes can make numbers or strings, and the number of arrays can be changed at will. Objective: to
