I have a python script get_telemetry.py that results in this data:

voltage = [[14.766786195683332, u'2017-10-11T06:00:00Z'], [14.756422268006672, u'2017-10-11T07:00:00Z'], [14.213013911141665, u'2017-10-11T08:00:00Z']]

I am trying to send this data to a php script where it will be converted into a php array, that will eventually end up in a google chart:

$voltagedata = ["2017-10-11 06:00:00" => 14.76, "2017-10-11 07:00:00"=> 14.75, "2017-10-11 08:00:00" => 14.21]

But when I try to encode the python list into json: print json.dumps(voltage)

and then try decode it in php:

$result = shell_exec('get_telemetry.py ' .  $imei);

$voltagedata = json_decode($result, true)

I get this error:

Notice: Array to string conversion

How can I get that python list of lists into a php array? I've tried to pass the python list into a dictionary first, but this gives me the same result. ie : from this example

When you print ANYTHING to the shell, it becomes a string. You need to parse the string in your php script (not sure how to do that in php) – Moinuddin Quadri Oct 15 '17 at 17:27
Make sure you `print json.dumps(data)` from your python script. Right now it looks like you have `print data`! Also, in PHP, use `json_decode`. – randomir Oct 15 '17 at 17:28
I don't use PHP, but don't you need `json_decode`? – juanpa.arrivillaga Oct 15 '17 at 17:28
which line number the warning come from? I guess the culprit is “$imei” – georgexsh Oct 15 '17 at 17:32
