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.

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.
