将PHP数据解析为python脚本

Question

this is my first time coding on python, i have a nested array that i want to parse it to python where the json will be process there and return the data back to php. But since this is my first time coding on python i have no idea how to parse json data from php to python vice versa. all i know is how to run python script from php using exec().

PHP

$alternative_val = array(
    array('1','0.5','3'),
    array('2','1','4'),
    array('0.333','0.25','1')
  );
 $json_alter = json_encode($alternative_val);

 $output = shell_exec('python test.py');
 echo $output;

after python receive the json data from php i should go into a list,

expected python result

X = [['1','0.5','3'],['2','1','4'],['0.333','0,25','1']]
print(X)

You can use json_encode function for your php script and modify your shell command with arguments. And after that you will get your json data in py script.

PHP:

 $alternative_val = array(
    array('1','0.5','3'),
    array('2','1','4'),
    array('0.333','0.25','1')
 );
 $json_alter = json_encode($alternative_val);

 $output = shell_exec('python test.py "' . $json_alter . '"');
 echo $output;

PYTHON:

import sys
x = sys.argv[1]
print(x)
