How to randomly select elements from a PHP array?

Below is an example code demonstrating how to use the PHP function array_rand() to randomly select one or more elements from an array.

$array = array('apple', 'banana', 'cherry', 'date', 'fig');

$randomKey = array_rand($array);
$randomValue = $array[$randomKey];

echo "随机抽取的元素是：" . $randomValue;

This code snippet will randomly select an element from the $array array and output it. If you need to randomly select multiple elements, you can specify the second parameter to indicate the number of selections.
