Accessing data in a php multi-dimensional array

Question

I have a multi-dimensional array and php seems to be returning an array instead of a value when I attempt to access the values directly. What am I doing to cause this?

The array looks like (via print_r):

Array ( 
[12] => Array ( [2016] => 93083.00 [2015] => 85367.00 [2014] => 69726.00 ) 
[11] => Array ( [2016] => 66730.00 [2015] => 65548.00 [2014] => 77936.00 ) 
[10] => Array ( [2016] => 84602.00 [2015] => 112070.00 [2014] => 102104.00 )
 )

I'm trying to access values using $arrayname[12][2016] but it is returning Array[2016] instead of 93083.

Is this a simple syntax mistake? Or am I missing part of the concept here? I've been trying to work this problem for hours so maybe I'm missing a simple explanation.

EDIT: the syntax above is actually correct, the issue was in the data entry: I was trying to access a key that didn't exist. I tried to delete the post, but can't since it has been answered.

Please show how you're attempting to print it out, because that is correct. — aynber

echo $chart3_array[1][2017]; doesn't output anything, while print_r($chart3_array); does. — Keith

Could this possibly be a type issue with the second key? I've tried it both as 2017 and "2017" though. — Keith

I found it, it was an error in the data being entered. Thanks for your help. I will delete the question shortly. — Keith

$arrayname[12] = [2016=>93083.00,  2015=> 85367.00 ] 
    ...
    ...
    echo $arrayname[12][2015] ; // prints 85367

i think your array has one more level. try $arrayname[12][2016][2016] .
