我使用Slim框架爲站點構建RESTful後端,使用PHP的PDO查詢數據庫。然而,當我試圖參數綁定到準備好的聲明,我得到以下錯誤:PDO將單引號添加到綁定參數
string(206) "SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''10'' at line 1"`
看起來好像是PDO我周圍用單引號綁定參數。我的路線代碼如下:
$app->get("/members/next10/:offset", function($offset) use($app) {
$app->response()->header('Content-Type', 'application/json');
try {
$pdo = connectToDatabase();
$query = $pdo->prepare("SELECT * FROM `members` LIMIT 10 OFFSET :offset");
$query->bindParam(":offset", $offset, PDO::PARAM_INT);
$query->execute();
$result = $query->fetchAll(PDO::FETCH_ASSOC);
if (!empty($result)) {
echo json_encode($result);
} else {
$app->response()->status(404);
}
} catch (PDOException $d) {
$app->response()->status(500);
var_dump($d->getMessage());
}
});
我錯過了什麼嗎?我嘗試從URL中抓取:offset
,並將其分配給$offset
,在綁定之前將其轉換爲整數,但這也沒有什麼區別。
