I have two files in my "py" file in the "www" in wamp (local server) the first file is python and the code is:

print("Hello")
print("Jane")
print("doe")

the script in php:

<!DOCTYPE>
<html>

<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type">
<title>php with py</title>
</head>

<body>
<h1>Hi</h1>
<?php

$output = array();
exec("py C:\wamp64\www\py\py_8.py", $output);
var_dump( $output);
?>

</body>

</html>

it doesn't work, I get this error:

C:\wamp64\www\py\py_8.php:19:
array (size=0)
  empty

I have checked in cmd that line:

py C:\wamp64\www\py\py_8.py

and it works!

what is wrong?

  • @napuzba answered well, check there first. Commented May 18, 2017 at 15:13
  • Check with phpinfo if the safe mode is active php.net/manual/pt_BR/function.phpinfo.php Commented May 18, 2017 at 15:17

You should use full path to python.

exec('"full-path-to-python" "C:\wamp64\www\py\py_8.py"', $output);

Try to enclose with the paths with ".
didn't understand.. I tried this: exec("<C:\Users\User\AppData\Local\Programs\Python> C:\wamp64\www\py\py_8.py", $output);
First, remove the <> . Also, verify that you python is also x64 (using python -v)

run python --help in the command line, you can find the python path in the output

python --help

usage: C:\Users\Roofe\AppData\Local\Programs\Python\Python35\python.exe [option] ... [-c cmd | -m mod | file | -] [arg] ... Options and arguments (and corresponding environment variables): -b : issue warnings about str(bytes_instance), str(bytearray_instance)

then set the python path in you php exec like,

exec("C:\Users\Roofe\AppData\Local\Programs\Python\Python35\python.exe C:\wamp64\www\py\py_8.py", $output);

got this: Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:\Users\User>PS C:\Users\Roofe> python --help 'PS' is not recognized as an internal or external command, operable program or batch file.
in the cmd window, run python --help, and first you have python installed.

check where your python is installed, and check the environment path
