Why does php function exec() return status code 2

Question

I am trying to run a simple python script from within my php application.

For test purposes, here is my code:

function run()
{
    $result = exec('python3.7 testPy.py',$output, $return_code); 
    dd($result, $output, $return_code); //dd() is alias for dump and die. 
} 
run();

testPy.py:

print('Ok')

if I run this command via console as root I get the following output:

root@xxx:Controller$ python3.7 testPy.py 
Ok

The same thing is with the www-data user:

www-data@xxx:Controller$ python3.7 testPy.py 
Ok

How ever, if call my php script via browser, I get the following output:

run.php on line 3: "" 
run.php on line 3: []
run.php on line 3: 2

run.php and testPy.py are in the same folder.

Any ideas are very welcome.

Thank for noticing, was copy paste error when preparing for this post. — AntonLevitsky

Try $result = exec('python3.7 ./testPy.py',$output, $return_code); — Markus Zeller

I noticed on some hosting servers the exec function in php is disabled by default. Check your phpinfo()

or

if(function_exists('exec')) {
    echo "exec is enabled";
}

Try this code in php file

$command = escapeshellcmd('python testPy.py');
$output = shell_exec($command);
echo $output;
