Enabling Python in PHP Gear on OpenShift PaaS

Normally one gear can run only one programing language. Here is Guide on Enabling Python in PHP Gear on OpenShift PaaS Where 2 Languages Can Be Used. This guide is a derivative of Using OpenShift PaaS Shell For OpenStack Python Clients.

Before Enabling Python in PHP Gear on OpenShift PaaS

We are not doing something which is officially documented. Hence, you should tag your PHP based app’s git as backup or use basic file level backup. It is better to use a new fresh cartridge. We can not give warranty about the functions.

Now, how we can call Python within PHP, there are many ways. We are providing a basic example. In order to call Python script from PHP, we need to write a script in this way :

#!/usr/bin/env python

1	#!/usr/bin/env python

If we save the Python script as example.py, we should chmod it rightly in this way :

chmod +x example.py

1	chmod +x example.py

Now from PHP we can call in this way :

<?php 

$command = escapeshellcmd('/path/to/example.py');
$output = shell_exec($command);
echo $output;

?>

1

2

3

4

5

6

7

<?php

$command = escapeshellcmd('/path/to/example.py');

$output = shell_exec($command);

echo $output;

?>

How we will use that matters, we can call it in this way :

$yourstring = system('python example.py yourargs', $retval);

1	$yourstring = system('python example.py yourargs', $retval);
