How to implement a random drawing program in PHP?

You can create a simple PHP random draw program by following these steps:

1. Create an array that includes a list of all participants in the raffle.
2. Generate a random number using the rand() function in PHP, and use this number to randomly select a person from an array as the winner.
3. Display the name of the winner on the webpage.

Here is a basic example of a PHP random draw program:

<?php
$participants = array("张三", "李四", "王五", "赵六", "孙七");

$winner = $participants[rand(0, count($participants) - 1)];

echo "恭喜" . $winner . "中奖！";
?>

In the above example, we start by creating an array with the names of 5 people, then use the rand() function to generate a random number to select a winner, and finally output the winner’s name on the page.

You can expand and customize according to your actual needs, such as adding more names to the list of personnel, setting multiple awards, and so on.
