注意：Array對字符串Converstion在Doctrain查詢

Question

說明：陣列至字符串轉換在學說查詢

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

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

$storesList = (string)$storesList; 

我改成了字符串，但在查詢它仍在考慮爲陣

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

Answer 1

首先改變$list[] = "'".$location['id']."'";到

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

現在做象下面這樣： -

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

而且

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