我正在尝试与Eloquent建立一个hasManyTrough关系,但目前还不清楚它是如何从文档中运行的.

表:

users
   - id
   - firstname
   - ...etc

accounts
   - id
   - user_id
   - username
   - ...etc

roles
   - id
   - permissions

account_role
   - id
   - account_id
   - role_id

楷模

<?php
class User extends Eloquent {

    public function account()
    {
        return $this->hasOne('Account');
    }

    // This is what I'm trying to achieve
    public function roles()
    {
        return $this->hasManyThrough('Role', 'Account');
    }
}

class Role extends Eloquent {

    public function accounts()
    {
        return $this->belongsToMany('Account')->withTimestamps();
    }
}

class Account extends Eloquent {

    public …

当我在PHP(v5.5.9)中执行以下代码时,会发生意外情况:

$valueAsCents = 54780 / 100 * 100;
var_dump($valueAsCents);
var_dump((int) $valueAsCents);

这回来了

float 54780
int 54779

所以显然没有小数的浮点值不等于int值.关于这里发生了什么的任何想法？
