php exec python script that writes file

Question

I need to execute a python script that writes a file in the same directory.

test.py :

print 'Hi! I was executed'

test2.py :

filename = 'sample.txt'
target = open(filename,'a')
target.write("Something Something")
target.close()

Php script:

<?
    exec('python test.py',$output1,$ret1);
    exec('python test2.py',$output2,$ret2);
?>

The first exec works fine but the second script does not, the return var $ret2 is 1. Both the commands work perfectly fine in the terminal. I guess it is a permission issue as php scripts are executed as 'nobody'.

Thanks in advance

try to give full path for filename = 'sample.txt'

For e.g.

filename = '/home/pranjal/sample.txt'

I would consider using a COM:

<?php
$WshShell = new COM("WScript.Shell");
$oExec = $WshShell->Run("[Your command here]", 0, false); 
?>

Mind you this will not work wonders running in a Linux server.

Also please consider that you are allowing your script to execute code, please make sure it's all safe when it needs to be :)

escapeshellarg()
escapeshellcmd()

Will remove the commands that you don't want to run.
