23. And now in PHP
24. composer require predictionio/predictionio
25. use PredictionIO\PredictionIOClient; $client = PredictionIOClient::factory(array('appkey'=> '…')); ! // Create a user $command = $client->getCommand( 'create_user', ['pio_uid' => 'florian'] ); $response = $client->execute($command);
26. use PredictionIO\PredictionIOClient; $client = PredictionIOClient::factory(array('appkey'=> '…')); ! // Create an item $command = $client->getCommand( 'create_item', ['pio_iid' => 'Game of Thrones', 'pio_itypes' => 1] ); $response = $client->execute($command);
27. use PredictionIO\PredictionIOClient; $client = PredictionIOClient::factory(array('appkey'=> '…')); ! // User likes an item $client->identify('florian'); $command = $client->getCommand( 'record_action_on_item', ['pio_action' => 'like', 'pio_iid' => 'Game of Thrones'] ); $client->execute($command);
28. use PredictionIO\PredictionIOClient; $client = PredictionIOClient::factory(array('appkey'=> '…')); ! // Top N recommendations for user $client->identify('florian'); $command = $client->getCommand( 'itemrec_get_top_n', ['pio_engine' => 'engine1', 'pio_n' => 10] ); $rec = $client->execute($command); print_r($rec);
