Question

我正在开发一个属性网站，该网站从CRM数据库中提取结果。撤回的结果是基于较大房产内的可用单位（即包含各种公寓的一个大街区）。我需要能够按每个属性推送一个图像数组但不是每个单元，但结果数组会带回每个属性和每个单元。这就是我的意思：

Array
(
    [0] => stdClass Object
        (
            [property_id] => 2
            [unit_id] => 5
            [property_name] => Morb House
            [address] => 123 Test Street, Blahtown, BL1 AHH
            [unit_name] => Apartment Number 1
            [max_guests] => 2
            [description] => This is a nice place
            [bedrooms] => 1
        )

    [1] => stdClass Object
        (
            [property_id] => 2
            [unit_id] => 6
            [property_name] => Morb House
            [address] => Some Road, Some Town, Anywhere
            [unit_name] => Apartment Number 2
            [max_guests] => 4
            [description] => This is a slightly bigger place
            [bedrooms] => 2
        )

    [2] => stdClass Object
        (
            [property_id] => 2
            [unit_id] => 11
            [property_name] => Morb House
            [address] => 123 Test Street, Blahtown, BL1 AHH
            [unit_name] => Cool Studio
            [max_guests] => 1
            [description] => This is a teeny weeny place
            [bedrooms] => 1
        )

    [3] => stdClass Object
        (
            [property_id] => 4
            [unit_id] => 12
            [property_name] => Fake Buildings
            [address] => 1 Fake Street, Anytown
            [unit_name] => Fake Apartment One
            [max_guests] => 1
            [description] => Some description here
            [bedrooms] => 1
        )

)

我将从另一个表中获取的图像将按属性ID进行过滤，我打算将其添加到与该属性相关的对象中。但是，由于可以在单个属性中预订多个单元，因此该属性ID在前3个结果中重复。理想情况下，我希望我的结果看起来像这样：

Array
(
    [2] => stdClass Object
        (
            [property_id] => 2
            [property_name] => Morb House
            [address] => 123 Test Street, Blahtown, BL1 AHH
            [units] => Array
            (
                [5] => stdClass Object
                    (
                        [unit_name] => Apartment Number 1
                        [max_guests] => 2
                        [description] => This is a nice place
                        [bedrooms] => 1
                    )
                [6] => stdClass Object
                    (
                        [unit_name] => Apartment Number 2
                        [max_guests] => 4
                        [description] => This is a slightly bigger place
                        [bedrooms] => 2
                    )
                [11] => stdClass Object
                    (
                        [unit_name] => Cool Studio
                        [max_guests] => 1
                        [description] => This is a teeny weeny place
                        [bedrooms] => 1
                    )

            )
        )

    [4] => stdClass Object
        (
            [property_id] => 4
            [property_name] => Fake Buildings
            [address] => 1 Fake Street, Anytown
            [units] => Array
            (
                [12] => stdClass Object 
                    (
                        [unit_name] => Fake Apartment One
                        [max_guests] => 1
                        [description] => Some description here
                        [bedrooms] => 1
                    )
            )

        )

)

如果密钥实际上是属性ID，并且该属性中的每个单元都有一个子对象，则由相关的单元ID键入。

我只需要在PHP中简单而干净地提供一些如何做到这一点的建议。

Answer 1

$out=array();
foreach($array as $item)
{
   $new = new StdClass;
   foreach(array('unit_name','max_guests','description','bedrooms') as $add){
     $new->{$add} = $item->{$add};
   }
   if(isset($item[$item->property_id])){
         $out[$item->property_id]->units[$item->unit_id] = $new; 
         continue;
   }
   $out[$item->property_id] = (object)array('property_id'=>$item->property_id,'property_name'=>$item->property_name,'address'=>$item->address,'units'=>array($item->unit_id=>$new));
}
print_r($out);

您可以获得所需格式的唯一方法是，如果您使用ORM并为您的属性和单位表设置了适当的关系设置。如果没有，那么你必须将现有结果转换为你想要的格式。

e.g。

<?php

// your current result set goes here
$units = $your_crm->database->get_units();

$properties = [];

foreach ($units as $_unit)
{
    $id = $_unit->property_id;

    $unit = [
        'unit_name'   => $_unit->unit_name,
        'max_guests'  => $_unit->max_guests,
        'description' => $_unit->description,
        'bedrooms'    => $_unit->bedrooms,
    ];

    if (isset($properties[$id])) {
        $properties[$id]->units[] = $unit;
    } else {
        $properties[$id] = (object) [
            'property_id'   => $_unit->property_id,
            'property_name' => $_unit->property_name,
            'address'       => $_unit->address,
            'units'         => [$unit]
        ];
    }
}

print_r($properties);
