我试图用一个查询将数据添加到多个表中。

这两个表是联系人和地址。我想问题出在我的地址表上。把我的地址表分开是个好主意吗？因为多个联系人可以共享同一地址。（家庭）
插入数据查询

$sql = "INSERT INTO contacts (firstName,lastName,nickName,cellNumber,homeNumber,workNumber) VALUES ($firstName,$lastName,$nickName,$cellNumber,$homeNumber,$workNumber) "
        . "INSERT INTO address(street,city,state,country) VALUES($street,$city,$state,$country) INSERT INTO contacts (email,birthday,memo)"
        . "values($email,$birthday,$memo)";

我的html表单

<fieldset>
                <legend>Register Form</legend>
                <div>
                    <input type="text" name="firstName" placeholder="First Name"/>
                </div>
                <div>
                    <input type="text" name="lastName" placeholder="Last Name"/>
                </div>
