Introduction

/**     $table gets the array from the database.     $user is the foreign key that represents the user who will receive the recommendation.   **/useTigo\Recommendation\Recommend;// import class$client =newRecommend();$client->ranking($table,$user);//optional third parameter refers to the score not accepted$client->euclidean($table,$user);//optional third parameter refers to the minimum accepted score$client->slopeOne($table,$user);//optional third parameter refers to the minimum accepted score

Configuration

constSCORE ='score';//scoreconstPRODUCT_ID ='product_id';//Foreign keyconstUSER_ID ='user_id';//Foreign key

Example

/**     Example using "rating: liked and disliked"     like: score = 1;  dislike: score = 0  **/$table = [        ['product_id'=>'A','score'=>1,'user_id'=>'Pedro'        ],        ['product_id'=>'B','score'=>1,'user_id'=>'Pedro'        ],        ['product_id'=>'A','score'=>1,'user_id'=>'João'        ],        ['product_id'=>'B','score'=>1,'user_id'=>'João'        ],        ['product_id'=>'C','score'=>1,'user_id'=>'João'        ]  ];useTigo\Recommendation\Recommend;// import class$client =newRecommend();print_r($client->ranking($table,"Pedro"));// result = ['C' => 2]print_r($client->ranking($table,"Pedro",1));// result = [];print_r($client->euclidean($table,"Pedro"));// result = ['C' => 1]print_r($client->euclidean($table,"Pedro",2));// result = [] ;print_r($client->slopeOne($table,'Pedro'));// result = ['C' => 1]print_r($client->slopeOne($table,'Pedro',2));// result = []
