用“and"从数组中分隔的列表在最后一个元素之前 [英] Comma separated list from array with "and" before last element

问题描述

我有一个数组 ($number_list)，它有一个动态生成的值列表.数组中至少有 1 个值，不超过 4 个.

I have an array ($number_list) that has a dynamically generated list of values. There will be at least 1 value in the array and no more than 4.

目前，我有一个很好的方法来使用逗号分隔的列表...

Currently, I have a nice way of having a comma separated list using this...

$comma_list = implode(', ', $number_list);

但是，我想保持英文惯例，并在最后一个元素之前加上and"这个词.所以，假设 $number_list 包含值 4, 5, 6, 7.我想回应这样的语句，列表是 4, 5, 6, and 7."

However, I'd like to keep with English convention and have the word "and" before the last element. So, let's say $number_list contains the values 4, 5, 6, 7. I would want to echo a statement like, "The list is 4, 5, 6, and 7."

任何想法如何将和放在那里?

Any ideas how to get that and in there?

推荐答案

尝试 array_pop() 获取最后一个元素，然后 array_push 修改并将元素推回:

Try array_pop() to get the last element, then array_push to modify and push the element back:

类似的东西

$last_element = array_pop($number_list);
array_push($number_list, 'and '.$last_element);

然后你可以做你的内爆:

Then you can do your implode:

$comma_list = implode(', ', $number_list);
