我正在尝试在我的数据库中存储具有各种结构的一些数据。我尝试这样做的方法是创建一个记录实体，并将条目（属性）附加到该记录的条件/值。
Record 1
-> Entity 1 = title:Fruit, dataString:Apple
-> Entity 2 = title:quantity, dataNumber:5
-> Entity 3 = title:color, dataString:red
etc...
Record 2
-> Entity 1 = title:Fruit, dataString:Apple
-> Entity 2 = title:quantity, dataNumber:5
-> Entity 3 = title:color, dataString:green
etc...
我希望能够返回所有颜色结果，其中Fruit == Apple quantity == 5。因此[红色，绿色]
我无法为每种类型的记录创建一个表格，因为我的数据非常复杂，并且每个记录都有不同的属性（条目）

var_dump($array);exit();
在上面的代码中，$ output将是color，$ matches将包含数量和水果。
显然上面的代码不起作用，因为它试图找到一个包含类型和水果的条目，这是不可能的。我需要返回具有与我的匹配数组匹配的兄弟条目的条目。
我可能不会以正确的方式解决这个问题。任何建议将不胜感激。

您需要使用EAV结构（实体，属性，值） - 该结构用于Magento和Drupal。祝你好运！:)

On下面似乎可以解决这个问题
public function options($matches, $output)
{
$qb = $this->createQueryBuilder('record');
$qb->innerJoin('record.entries', 'entry');
$qb->where('entry.title = :output');
$params = ["output" => $output];
foreach ($matches as $title => $value) {
$title1 = str_replace(" ", "_", $title)."match";
$qb->innerJoin('record.entries', $title1.'entries');
$qb->andWhere($title1.'entries.title = :'.$title1 .' AND ('.$title1.'entries.dataString = :'.$title1.'dataString OR '.$title1.'entries.dataNumber = :'.$title1.'dataNumber)');
$params[$title1] = $title;
$params[$title1."dataString"] = $value;
$params[$title1."dataNumber"] = $value;
}
$qb->setParameters($params);
$array = $qb
//->select('entry1.title, entry1.dataString, entry1.dataNumber, entry.title as title1')
->select('entry.dataString, entry.dataNumber')
->distinct()
->getQuery()
->getResult();
$arrayFlat = iterator_to_array(new \RecursiveIteratorIterator(new \RecursiveArrayIterator($array)),false);
$arrayNotNulls = array_filter($arrayFlat, 'strlen');
$arrayKeysFixed = array_values($arrayNotNulls);
return $arrayKeysFixed;
}
