PHP注意:未定义索引:内容[重复]

This question already has an answer here:

I know this question sounds silly, and seems like a duplicate to the other questions, but I can almost assure you it is not a duplicate.

I am getting an issue from PHP: Notice: Undefined index: content in FILE_PATH on line 21

Line 21: echo htmlentities($about['content']);

I know for sure that $about['content'] is set because for debugging, I have

print_r($about)

Which gives me

    Array
(
    [0] => Array
        (
            [id] => 1
            [page] => About Us
            [content] => I have stuff here.... content for test purpose.
        )

)

Any help is appreciated. Thanks

Edit This question is not duplicate because all the answers to the other questions don't talk about array of array. Please do not mark this question as duplicate.
