Data interaction between PHP and Python

Recently, I decided to use tp5 for APP interface development and Python for data analysis in a project. Then I faced a question: How do PHP and Python interact with data?

Ideas

The way I solved this problem was to use PHP's passthru function to call the command to run the Python script.

Implementation

Call the command in PHP to run the Python script

//php.php 

If there are multiple parameters, separate them with spaces

Receive the parameters passed in by PHP in Python

sys.argv[] is used to obtain the entry parameters passed by PHP into python

//python.py import sys params = sys.argv[1] #即为获取到的PHP传入python的入口参数 print(params);

If in Receive multiple parameters in Python

params = sys.argv[1:]

Return parameters from Python

To return multiple values from Python, you need to write the values into a tuple, and then Convert it to json through json.dumps() and print it. You can get the json printed by the Python script through passthru in PHP

import sys import json params = ('Google', 'Runoob', 1997, 2000); json_str =json.dumps(params); print(json_str);

You also need to add @ before passthru in PHP, otherwise the following prompt will be reported

Notice: Array to string conversion in php.php on line 6

Effect

Run the PHP file that calls the Python script, and the output value in the browser is the value printed by Python.
