call python from php with 2 return values

I have a python script who is returning 2 values, humidity and temperature:

Temperature: 1.58050537109
Humidity: 89.2761230469

I call this srcipt from a PHP page but only one value is printed

<?php
echo exec("sudo python /home/pi/sht/sht31.py 2>&1");
?>

and only one humidity is printed. Could you please help me to print both value ? Thank you

now output is :

array(5) { [0]=> string(5) "False" [1]=> string(4) "True" [2]=> string(5) "False" [3]=> string(26) "Temperature: 1.56982421875" [4]=> string(23) "Humidity: 89.3859863281" }

with this code :

exec('sudo python /home/pi/sht/sht31.py' , $output);
var_dump($output);

If you call exec() with only command string, then it will return only the last line of output. To capture everything call it with second parameter to get all output:

exec('command', $output);
var_dump($output);
