如何在循环中构建自定义的2D数组 我需要从我的数据库检索的记录中构建一个多维数组。 这是我拥有的代码：

Question

数据库中的所有记录都在数组中的一个接一个。我需要使用多维数组来优化它。

$college_temp = array();
foreach($data['colleges'] as $college)
{
    $college_temp[] =  $college;
}

// Echo the first one's name
echo $college_temp[0]['name'];

// Echo the second one's url
echo $college_temp[1]['url'];

$college_temp = array();
$i = 0;
foreach($data['colleges'] as $college)
    {

        $college_temp[$i]['name'] =  $college->name; 
        $college_temp[$i]['abbrev'] =  $college->abbrev;
        $college_temp[$i]['long_name'] =  $college->long_name;
        $college_temp[$i]['long_abbrev'] =  $college->long_abbrev;
        $college_temp[$i]['url'] =  $college->url;
        $college_temp[$i]['description'] =  $college->description;
        $i++;

    }
    // var_dump($college_temp); // uncomment to check array contents
