Question

我在laravel 4中查询数据库，但无法在此处访问返回的值是代码：

public class Customer
{
    private String city;
    private String address;
    private String cel;
    private String email;
    private String name;
    private int customerID;

    public enum camposCust{
        city,
        address,
        cel,
        email,
        name,
        _customerID
    }
    public void setCity(String city)
    {
        this.city = city;
    }

    public String getCity()
    {
        return city;
    }

    public void setAddress(String address)
    {
        this.address = address;
    }

    public String getAddress()
    {
        return address;
    }

    public void setCel(String cel)
    {
        this.cel = cel;
    }

    public String getCel()
    {
        return cel;
    }

    public void setEmail(String email)
    {
        this.email = email;
    }
    public String getEmail()
    {
        return email;
    }

    public void setName(String name)
    {
        this.name = name;
    }

    public String getName()
    {
        return name;
    }
    public void setCustomerID(int customerID)
    {
        this.customerID = customerID;
    }

    public int getCustomerID()
    {
        return customerID;
    }
}

所以该函数返回此public static function getCityIdByName($cityname){ $cityid = DB::select( DB::raw(" SELECT id FROM cities WHERE match(city_name) against('*" . $cityname . "*' IN BOOLEAN MODE ) " )); return $cityid; }并且我需要获得价值＆＃34; 1＆＃34;，我尝试了[{"id":1}]和$cityid->id以及$cityid['id']但这一切都是返回错误，也不是字符串，当我回显它时，它抱怨数组不是字符串$cityid[0]

Answer 1

我用这段代码解决了这个问题：

git push -u origin master

Answer 2

即使它有效，你也可以改进它

如果你有几个结果，你只需要第一个数组就可以得到所有结果。

您还可以在查询中使用->first()来获取第一个避免使用[0]的对象。
