I need application facebook (like statut by our multiple account)

context: We have a facebook application that enables you to schedule posts on the wall of many facebook users (authorization scope publish_stream) the project: we would like every post on the wall of these users is automatically liked by all our users Example: Post programmed 31/03/2015 at 14h on the accounts: 005415, 1412313, 151202, 456456, 5465436 Text: here is the great test Links: [login to view URL] The post will be published on the account 005415 And users 1412313, 151202, 456456, 5465436 must like this post automatically The post will be published on the account 1412313 And users: 005415, 151202, 456456, 5465436 must like this post automatically etc ... Conclusion: is what allows facebook api (once the ID returned by post facebook at the time of publication) to like status (scope authorization) or is what we have to use the facebook cookie for each user and go through a php script?
