You need to use this if you want it as an array

$array = json_decode($var, true);

Otherwise it will return the json as a object instead of an array

Doing this should let you access it like so:

$fl = $array[0]['faceRectangle']['left'];

You're missing the variable name and the first array dimension. – Barmar Apr 26 '17 at 16:19
@Barmar Haha, good point. – Andrew Rayner Apr 26 '17 at 16:21
You're still missing the first dimension. Did you notice that the objects are in an array? – Barmar Apr 26 '17 at 16:21
Nope, slipped right past my eyes. – Andrew Rayner Apr 26 '17 at 16:22
