我们为什么要获取对象？

I'm not referring to a particular database driver or so but we, as PHP developer, have always had the choice to use either arrays or object as return type of a database query.

我不是指特定的数据库驱动程序,但作为PHP开发人员,我们总是可以选择使用数组或对象作为数据库查询的返回类型。

So for example we could access the column "title" with either $array['title'] or $object->title.

因此,例如,我们可以使用$ array ['title']或$ object-> title访问列“title”。

For example mysql PHP built-in functions mysql_fetch_assoc() and mysql_fetch_object() give this choice.

例如,mysql PHP内置函数mysql_fetch_assoc()和mysql_fetch_object()给出了这个选择。

I noticed that the object-way (as I'm gonna call it) is much worse:

我注意到对象方式(因为我要称它)更糟糕的是:

You cannot specify table names that contains special chars such as . or - and use them with objects.

您不能指定包含特殊字符的表名称,例如。或 - 并将它们与对象一起使用。

Object are usually heavier than arrays

对象通常比数组重

Object doesn't have all the cool functions to manage them as arrays do

对象没有像数组那样管理它们的所有酷函数

Arrays better explain the table structure rather then property chaining.

数组更好地解释表结构而不是属性链。

There are few other little things about object vs array war regarding database results but these are the main ones.

对于数据库结果,关于对象与阵列战争的其他一些小事情,但这些是主要的。

Why do people even take the object-way as choice?

为什么人们甚至把对象作为选择?

2 个解决方案

#1

You can specify table names that contains special chars such as . or -

您可以指定包含特殊字符的表名称,例如。要么 -

Object are more flexible than arrays

对象比数组更灵活

Object have all the cool functions that you can imagine to manage them, you just have to write a few of them

对象具有您可以想象的所有很酷的功能来管理它们,您只需要编写一些它们

Arrays don't cleanly express relationships between tables, object mapping does.

数组不能干净地表达表之间的关系,对象映射确实如此。

#2

I mostly use it because $user->name is a lot easier on the eyes than $user['name']

我主要使用它,因为$ user-> name在眼睛上要比$ user ['name']容易得多
