Running venv Python script from PHP

I am running many python scripts from PHP. My php script template as below: 

<?php
setlocale(LC_ALL, "en_US.utf8");
header("Content-Type: application/json");
header("Access-Control-Allow-Origin: *");

$command = escapeshellcmd("/usr/bin/python2.7 /path/to/script");
$args = escapeshellarg($_GET["title"]). " " . 
escapeshellarg($_GET["user"]);
$output = shell_exec($command . " " . $args);
echo $output;

But now I need to run some python scripts which are in virtual environment.

I tried to replace /usr/bin/python2.7 with ./www/python/venv/bin/python3, but it does not work.

So how to run it in PHP?

Ideally You should use APIs, that is the best practice. But if you don't have API available you can use pipe.
That can be used like this function: exec_command($command) where,
$command = $command . " " . $args
Below is the code:

<?php
setlocale(LC_ALL, "en_US.utf8");
header("Content-Type: application/json");
header("Access-Control-Allow-Origin: *");

$command = escapeshellcmd("/usr/bin/python2.7 /path/to/script");
$args = escapeshellarg($_GET["title"]). " " . 
escapeshellarg($_GET["user"]);

$command = $command . " " . $args;

$output = "";
$hd = popen($command, "r");
while(!feof($hd))
{
  $output .= fread($hd, 4096);
}
pclose($hd);

echo $output;

?>

To really run venv you would need to do three steps in the shell:

  1. Change into project root.
  2. source venv/bin/activate
  3. run python path/to/script

Prerequisite you already have prepared a virtual env for the project.

You could combine this three steps into a bash script and call this script from PHP.
