私は単純な配列を持っています:

$array_attributes_IDS = array(1,2);

配列から id_attribute を持つ会社を取得するクエリを書きたいと思います。

これを試して、

$array_attributes_IDS = array(1,2);
$finalArray = implode(',', $array_attributes_IDS);
$arrCount = count($array_attributes_IDS);

$query ="    SELECT com.name
             FROM   company com
             INNER JOIN company_to_attributes att
                ON com.id_company = att.id_company
             WHERE  att.id_attributes IN ($finalArray)
             GROUP  BY com.name
             HAVING COUNT(*) = $arrCount";

TEST両方の属性が含まれているため、これは 1 つの会社のみを返します。

以下を試してください：

    $array_attributes_IDS = array(1,2);
    $finalArray = implode(',', $array_attributes_IDS);
    $query = "SELECT C.name FROM company_to_attributes CA INNER JOIN company C ON CA.id_company = C.id_company WHERE CA.id_attributes IN ($finalArray)";

これが役立つことを願っています。
