运行python文件并读取输出

Question

I'm trying to run python file from PHP

What I'm looking for is :

1- run python file from index.php

2- read the output of python file and show it in index.php

Example :

# test.py


import sys

user = sys.argv[1]
password = sys.argv[2]

def read():
    if user == "[e-mail]" and password == "123456":
        return "ok, registerd"
    else: return "I can\'t"
try: read()
except: pass

And in index.php should be some thing this :

<?php
$read = exec("python test.py [e-mail] 123456");

if($read == "ok, registerd")
    {
        echo "succesful registerd";
    }
else ($read == "I can\'t")
    {
        echo "failed";
    }

?>

I'm not sure what should I do in index.php how can I do it?

Answer 1

First, your last else is wrong on the php script,

instead of:

else ($read == "I can\'t"){

use:

else if($read == "I can\'t"){

Your python script was not working either. I didn't debug it, simply wrote a new one that works.

test.py

import sys

user = sys.argv[1]
password = sys.argv[2]

if user == "[e-mail]" and password == "123456":
    print  "ok, registered"
else: 
    print  "NOT registered"

index.php

<?php
/*
Error reporting helps you understand what's wrong with your code, remove in production.
*/
error_reporting(E_ALL); 
ini_set('display_errors', 1);

$read = exec("python test.py [e-mail] 123456");
if($read == "ok, registered")
    {
        echo "ok, registered";
    }
else if($read == "NOT registered")
    {
        echo "failed";
    }
?>
