I have to pass an array from a php file to python file but my code is giving output NULL

Question

PHP code:

Answer 1

There is incorrect data for json.dump() in Python

# Generate some data to send to PHP
result = {'23','4'}

So this give error, not json string

import sys, json

# Generate some data to send to PHP
result = {'23','4'}

# Send it to stdout (to PHP)
print json.dumps(result)

and PHP get NULL as $result from Python so you get NULL on screen - in browser

Use (for example):

# Generate some data to send to PHP
result = {'a':'23','b':'4'}

and json.dump() will work fine.
