调用python脚本的php脚本在ssh终端中工作，但在浏览器窗口中没有输出

Question

The following pieces of code when executed using php -f phptest.php gave the output (server is a GCP virtual instance running Centos7):

[[1, 2, 3], [4, 5, 6], [7, 8, 9]]
string(34) "[[1, 2, 3], [4, 5, 6], [7, 8, 9]]"

In the terminal window. On the other hand the same code when run using the server IP and appropriate URL gives:

string(0) ""

Here are the two scripts :

#!/usr/bin/env python  
def foo():    
    x=str([[1,2,3],[4,5,6],[7,8,9]])  
    return x  
x=foo()  
print(x)  

and

<?php
$command = "python_location pyfile.py"
escapeshellcmd($commmand);
$output = shell_exec($command);
$strout=print_r($output,true);
echo($strout);
var_dump($strout);
?>

The server doesn't have a directory /var/log/apache2/error.log. Instead i was able to find /var/log/httpd/error_log which contains the following:

[Sun Jun 16 05:04:34.269345 2019] [auth_digest:notice] [pid 21434] AH01757: generating secret for digest authentication ...

'server-generated directory index forbidden by Options directive' leads me to believe that this could possibly be changed through httpd.conf possibly?

Ideally the output in the browser would match the one I get in the ssh terminal

Thanks and Regards

I think maybe your PHP version is not updated and I tried in my pc and it is working fine. Try to update PHP
