Retrieve a Random Element from an Array

This question addresses the issue of obtaining a random element from an array. Specifically, the array $items contains a series of numbers, and the goal is to retrieve a random value from that array.

To achieve this, the array_rand() function is employed. This function accepts an array as its argument and returns a random index from the array. The returned index can then be used to access the corresponding element from the array.

The code snippet provided in the answer section demonstrates this process:

echo $items[array_rand($items)];

In this code, array_rand($items) generates a random index within the $items array. This index is then used to retrieve the corresponding element, which is then printed to the screen.

By utilizing array_rand(), you can efficiently and randomly select an item from an array, regardless of its size or contents.
