如何以一种更具可读性的方式随机播放数组或字符串列表？ [英] How to shuffle my Array or String list in a more readable way?

问题描述

假设您想要一个可读性强，易于编辑的项目列表，并以逗号分隔，然后从该列表中回显3个随机项目。数组或字符串无关紧要。现在，我得到了以下工作（感谢webbiedave！）

Imagine you want to have a very readable, easily editable list of items, separated by comma's only, and then echo 3 random items from that list. Array or string doesnt matter. For now, I got the following working (Thanks webbiedave!)

$fruits = array('Mango', 'Banana', 'Cucumber', 'Pear', 'Peach', 'Coconut');

$keys = array_rand($fruits, 3);   // get 3 random keys from your array
foreach ($keys as $key) {         // cycle through the keys to get the values
    echo $fruits[$key] . "<br/>";
}

输出：

Coconut
Pear
Banana

唯一未解决的问题是列表不是我希望的那样可读：
就个人而言，我非常喜欢输入列表不带引号，例如 Mango 而不是'Mango'，意思是最好这样：

Only thing unsolved here is that the list is not so readable as I wished: Personally, I very much prefer the input list to be without the quotes e.g. Mango as opposed to 'Mango' , meaning preferably like so:

（芒果，香蕉，黄瓜，梨，桃子，萨瑟恩瓜，椰子）

是这个很容易吗？非常感谢您的输入。

Is this easily possible? Thanks very much for your input.

推荐答案

$input = explode(',', 'Mango, Banana, Cucumber, Pear, Peach, Suthern Melon, Coconut');
$input = array_map('trim', $input);
