PHP parse dict output from python script

Question

How do I parse a dict output from a python script to a PHP array? My PHP file contains the line exec('/bin/python ~/somescript.py', $out, $err);. And my python script prints a dict with something like

d = {0: "a", 7: "d", 23: ["e", "z"]}
print(d)

But this doesn't work, $out[0] in my PHP file is just a really long string an array. I've also tried to use print(json.dumps(d)), same result (but with escaped " ).

It shouldn't be json.loads(d) as .dumps is used for encoding a python object to a json string (what I need). And .loads is used for decoding a json string to a python object. See docs.python.org/3/library/json.html — Legatio

$out is the output of the python script. See php.net/manual/de/function.exec.php. — Legatio

Use print(json.dumps(d)) in your Python script. Trim the dumps output by passing it separators=(',', ':') with the default indent=None so that the JSON is dumped to one line. So:

print(json.dumps(d, indent=None, separators=(',', ':')))

After that json_decode($out) or json_decode($out[0]) in your PHP script.
