PHP Notice: Undefined index: content

Question

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.

@RiggsFolly You right. That's why I needed clarification. I missed how I had to arrays, I can't figure out why but it works anyways. — Dev, Sep 22 '16 at 22:59
@RiggsFolly While I too agree closing it but the OP needed clarification. So technically this is not a duplicate. — Praveen Kumar Purushothaman, Sep 23 '16 at 02:08

From your print_r looks like you need to correct the source, or use:

echo htmlentities($about[0]['content']);

The $about is an array of array that contains the content index. One of the solution is to use:

$about = $about[0]; // Only if you know that this is the only case.

The right way is to correct at the source, why it is not being a source array, but has another sub-array.

Thanks a lot. I have no idea why it's an array of array. Thanks again – Dev Sep 22 '16 at 23:01
