在PHP循环中建立逗号分隔的字符串 [英] Build comma separated string in PHP Loop

问题描述

你们好，我需要这样做，

Hello Guys i need to do this,

我有一个普通循环

foreach ($stuffs as $stuff) {
echo $stuff;
}

让我们假设$ stuff是我拥有的mysql表的'id'，我不想在下一个结果中显示，所以我想构建一个像这样的字符串

Lets assume $stuff is an 'id' of a mysql table what i have and i dont want to be showed in next results, so i want to build a string like this

1,23,54,67 (comma separated) 

因此该字符串将在mysql查询中排除已显示的结果. 我该怎么办?

So that string will be in mysql query to exclude results that already have been shown. how can i do that?

应该内爆吗?我该如何实现?

Should be with implode? How can i achieve that?

推荐答案

内置应该是这样的工具:

implode should be the tool:

implode(",", $stuffs);

将返回一个用逗号分隔的列表.

will return a comma separated list.

$myarray=array(1,2,"hello",4,5);
echo implode(",", $myarray);

返回

1,2,hello,4,5
