There's an item in the hand that wants to check out some API for built-in functions

Novice Contacts PHP has a project;
Inside there are Fetch_all, fetch_one_array,update,insert,count these built-in functions, want to check the API, probably can read what meaning, but want to check the API,

`$db = new Mysql();$db -> fetch_all(sql);$db -> fetch_one_array(sq);$db -> update(‘tablename’，data,where);$db -> insert(‘tablename’,data);$db -> count(‘tablename’，where);`
