In PHP assignment expressions always return the assigned value. So $_config[0] =& $config returns $config - but not the variable itself, but a copy of its value. And returning a reference to a temporary value wouldn't be particularly useful (changing it wouldn't do anything).
在PHP赋值表达式中,总是返回赋值。所以$_config[0] =& $config返回$config -但不是变量本身,而是它的值的一个拷贝。返回一个临时值的引用不会特别有用(改变它不会做任何事情)。
Update
This fix has been merged into CI 2.2.1 (https://github.com/bcit-ci/CodeIgniter/commit/69b02d0f0bc46e914bed1604cfbd9bf74286b2e3). It's better to upgrade rather than modifying core framework files.

this has been modified in codeigniter 2.2.1...usually not best practice to modify core files, I would always check for updates and 2.2.1 came out in Jan 2015
这在codeigniter 2.2.1中被修改了……通常不是修改核心文件的最佳实践,我总是检查更新,2.2.1在2015年1月发布

It's not a better idea to override the core.common file of codeigniter. Because that's the more tested and system files....
重写codeigniter的core.common文件不是更好的主意。因为更多的测试和系统文件....
I make a solution for this problem. In your ckeditor_helper.php file line- 65
我对这个问题提出了一个解决方案。在你ckeditor_helper。php文件行- 65
if($k !== end (array_keys($data['config']))) {

Change this to-->
改变这个- - >
$segment = array_keys($data['config']);

I think this is the best solution and then your problem notice will dissappear.
我认为这是最好的解决办法,然后你的问题通知就会消失。
