There is a web application written in PHP and HTML. What I want is to filter a users input for a variety of cases and sanitize it. For example, I want to compare the input from a form (string) with a list of allowed strings and depending if it is right or wrong to trigger the suitable PHP function to handle this.
My question is how to bind the user input with the python script and then the outcome of this python script as an input for PHP?
thanks
You can call the Python script from your PHP file as a shell command, passing it JSON-formatted arguments. Then have the Python script output the response (also JSON encoded) and have the PHP file capture that. Here's an example I used recently, cobbled together from the links below:
PHP file:
$py_input = ... // Your data goes here.
// Call the Python script, passing it the JSON argument, and capturing the result.
$py_output = shell_exec('python script.py ' . escapeshellarg(json_encode($py_input)));
$py_result = json_decode($py_output);
Python file:
import json
php_input = json.loads(sys.argv[1]) # The first command line argument.
# Do your thing.
php_output = ... # Whatever your output is.
print json.dumps(php_output) # Print it out in JSON format.
executing Python script in PHP and exchanging data between the two
