注意：Doctrine Query 中数组到字符串的转换

foreach($listLocations as $k=>$location){
    $list[] = "'".$location['id']."'";
}

$storesList = implode(',', $list); // 打印字符串(23)"'191','195','215','265'"

$storesList = (string)$storesList;

我把它改成了字符串，但在查询中它仍然认为是数组

$sql="SELECT * from tbl_students WHERE s.store_id IN (".$storesList .")";
$conn = $this->getEntityManager()->getConnection();     
$stmt = $conn->prepare($sql);

Answer 1

a) 首先改变：

$list[] = "'".$location['id']."'";

到

$list[] = $location['id'];

b) 现在执行如下操作：-

$storesList = "('".implode("','", $list)."')";

c) 和

$sql="SELECT * from tbl_students WHERE s.store_id IN $storesList";
