Question

我在cookie中有一个id数组。当我打印cookie数组时，它打印如下： ["39","580"]。我需要访问id 39和580。

    $queryordenar = $db->prepare("SELECT id FROM property 
    WHERE id IN (:list) ORDER BY price ASC");
    $queryordenar->execute(array(
    'list' => $array
     ));

您无法将数组作为参数传递。你需要爆炸数组，传入一个？对于每个值，然后将正确的值绑定到每个占位符：

$bindPlaceholders = [];
foreach ($array as $val) {
    $bindPlaceholders[] = "?";
}
$bindString = "(".implode(",", $bindPlaceholders).")";
$queryordenar = $db->prepare("SELECT id FROM property WHERE id IN ".$bindString." ORDER BY price ASC");
foreach ($array as $i => $val) {
    $queryordenar->bindValue($i + 1, $val); // binding starts at 1
}
$queryordenar->execute();

cookie中的数组，使用pdo查询访问
