我想删除最后一个'，'并取回剩下的字符串:

I would like to remove the last ',' and get the remaining string back:

OUTPUT: a,b,c,d,e

最快的方法是什么?

推荐答案

首先，我尝试不带空格rtrim($arraynama, ",");并得到错误结果.

First, I try without a space, rtrim($arraynama, ","); and get an error result.

然后我添加一个空格并获得良好的结果:

Then I add a space and get a good result:

$newarraynama = rtrim($arraynama, ", ");
