Pass variable from PHP to Python

Question

I am trying to pass the value of a variable from php to a python script.

php:

<?php 
$item = array('warren');
$command = escapeshellcmd('hello.py $item');
$output = shell_exec($command);
echo $output;
?>

python:

#!/usr/bin/env python
import sys
input = sys.argv[1]
print input

This results in $item displayed. I've tried all manner of different quotation marks, but still can't get the actual value (warren) to be passed. How do I get the value stored in $item to get passed, not the literal? I've also tried How to pass variable from PHP to Python?

Php:

<?php                                            
$item = array('warren');                                                  
$output = shell_exec('hello.py' . $item);
echo $output;
?>

But this gives me error:

Notice: Array to string conversion in C:\wamp64\www\crud\clientdetails.php on line 613

You can do either,

$output = shell_exec('hello.py ' . implode(',', $item));

Then explode the string in Python or you could pass only value in the array,

$output = shell_exec('hello.py ' . $item[0])

The reason you are getting the error is because you are trying to pass an array as a string.

If you want to pass the data in $item. You would need to do:

$string;
foreach ($item as &$value)
{
  $string .= $value . ",";
}
$output = shell_exec('hello.py' . $string);

Turns the $item array into a string which can then be passed into your python
