访问php中的对象数组

I am using Doctrine (DQL) with ZF2 to perform the following query:

我正在使用带有ZF2的Doctrine(DQL)来执行以下查询:

$qb->select('a.schoolID, a.schoolName')
    ->from('College\Entity\School', 'a');
$schools=$qb->getQuery()->getResult();

This returns and array of objects or a two dimensial Array as such:

这将返回对象数组或二维数组,如下所示:

array (size=2)
  0 => 
    array (size=2)
    'schoolID' => int 1
    'schoolName' => string 'Alabama A & M University' (length=24)
1 => 
   array (size=2)
    'schoolID' => int 2
    'schoolName' => string 'University of Alabama at Birmingham'

My question is: How and What's the best approach to access an Array of this type with unknown numbers of objects in it.

我的问题是:如何以及什么是访问此类型数组的最佳方法,其中包含未知数量的对象。

What do you mean? It's a plain array.

你什么意思?这是一个简单的阵列。

You can, for example, loop through it like:

例如,您可以循环遍历它:

foreach ($schools as $school)
{
   // Do something with $school, like:
   echo $school['schoolName'];
}

You can query the number of items like count($schools).

您可以查询计数($学校)等项目的数量。
