如何在Python和PHP之间传输数据 [英] How to transfer data between Python and PHP

问题描述

我有一个Python脚本，该脚本使用print和shell_exec()将一堆文本输出到PHP.我还必须在两者之间发送字典，以存储一些脚本信息.这是我的代码的简化版本:

I have a Python script that outputs a bunch of text to PHP using print and shell_exec(). I also have to send a dictionary between the two, to store some script information. Here is a simplified version of my code:

import json

# Lots of code here

user_vars = {'money':player.money}
print(user_vars)
print(json.dumps(user_vars))

输出(在PHP中):

{'money': 0} {"money": 0}

同样的事情，除了JSON带有双引号.

So the same thing, except JSON has double quotes.

如果要使用JSON(print(json.dumps(user_vars))，输出{"money": 0}，请注意双引号)来传输数据，这将是我要使用的代码:

This is the code I would use if I wanted to use JSON (print(json.dumps(user_vars)), which outputs {"money": 0}, note double quotes) to transfer data:

<?php
$result = shell_exec('python JSONtest.py');
$resultData = json_decode($result, true);
echo $resultData["money"];
?>

我有两个问题:

1. 是否出于某些原因我应该使用print(user_vars)而不是 print(json.dumps(user_vars))，反之亦然?
2. 还有其他方法可以传输user_vars/json.dumps(user_vars)而不在最终的PHP页面中看到它，而不必将它们转储到实际的.json文件中吗?还是我会以错误的方式解决这个问题?

1. Is there some reason I should use print(user_vars) instead of print(json.dumps(user_vars)), or vice versa?
2. Is there some other way to transfer user_vars/json.dumps(user_vars) without it being seen in the final PHP page without having to dump them in an actual .json file? Or am I going about this problem in the wrong way?

我的代码基于问题这里.

推荐答案

此代码可以解决问题.

import json
data = {'fruit':['oranges', 'apples', 'peaches'], 'age':12}
with open('data.json', 'w') as outfile:
    json.dump(data, outfile)

PHP

<?php
$string = file_get_contents("data.json");
$json_a = json_decode($string, true);
echo $json_a['age']; # Note that 'fruit' doesn't work:
                     # PHP Notice:  Array to string conversion in /var/www/html/JSONtest.php on line 4
                     # Array
?>

此方法仅适用于字符串，但确实解决了我的问题，我可以不使用列表/数组来解决这个问题.

This method only works with strings, but it does solve my problem, and I can get around not using lists/arrays.
