从php函数执行python脚本?

I want to execute a python script,test.py, from a php function.

#!/usr/bin/env python
import random

def test() :
   print("test success")

if __name__ == '__main__':
    test()

I can successfully execute it using php command line:

php -r '$message = exec("python3 ~/../scripts/test.py"); print_r($message);' 

I've added the following to my php code:

$message = exec("python3 ~/../scripts/test.py", $output, $return_val); 

When I execute it, nothing is output (no errors in devtools). When I print the variables, $output and $message are empty and $return_val is 2 (misuse of shell builtins according to Bash documentation).

I know exec() is allowed after adding the following into the same function:

if (exec('echo TEST') == 'TEST')
    {
      echo 'exec works!';
    }

What could be causing this error? How can I execute the python script with php?

我想从php函数执行python脚本 test.py

 #!/ usr / bin / env python 
import random 
 
def test():
 print(“test success”)
 
if __name__ ==  '__main __':
 test()
   
 
 

我可以使用php命令行成功执行它:

   php -r'$ message = exec(“python3~ /../ scripts / test.py”); 的print_r($消息);”  
   
 
 

我在PHP代码中添加了以下内容:

  $ message = exec(“python3~  /../scripts/test.py“,$ output,$ return_val);  
   
 
 

执行时,不输出任何内容(devtools中没有错误)。 当我打印变量时, $ output $ message 为空, $ return_val 为2(根据Bash文档滥用shell builtins )。

我知道在将以下内容添加到同一个函数后, exec()是允许的:

  if(  exec('echo TEST')=='TEST')
 {
 echo'exec works!'; 
} 
   
 
 

可能导致此问题 错误? 如何用php执行python脚本?

    Your web server does not share your home directory, so ~ will point to the wrong place. Specify the full path of the file instead.

    python3 will exit with 2 when it can't find the file, along with a helpful message on stderr. The web server error logs will confirm this, as will adding 2>&1 to your command to capture stderr as stdout in your variable.
