Question

我有这段代码

while ($row = mysql_fetch_array($result)) {
    // temp user array
    $product = array();
    $product["user_id"] = $row["user_id"];
    $product["user_name"] = $row["user_name"];

    // push single product into final response array
    array_push($response["products"], $product);
}
// success
$response["success"] = 1;

// echoing JSON response
echo json_encode($response);

它给了我这个结果

{"products":[{"user_id":"2","user_name":"BOZ2"},{"user_id":"25","user_name":"POZ"},{"user_id":"28","user_name":"a"}],"success":1}

现在我正在使用......

$row = $stmt->fetch();
if ($row) {

    $sql = "select  statement";

     $stmt = $db->prepare( $sql );
    // execute the query
    $stmt->execute();
    // fetch the results into an array
     $result = $stmt->fetchAll( PDO::FETCH_ASSOC );
     $response["products"] = array();
     $product["user_name"] = $row["user_name"];
     $product["user_id"] = $row["user_id"];
    // convert to json
    $json = array_push($response["products"], $product);
    // echo the json string
    $response["success"] = 1;
    // echoing JSON response
     echo json_encode($response);

它给了我这个......同样的结果

{"products":[{"user_name":"BOZ2","user_id":"2"}],"success":1}{"products":[{"user_name":"BOZ2","user_id":"2"}],"success":0,"message":"success"}

如何让它循环遍历所有结果

Answer 1

fetchAll返回数组中的所有行。你只需要这个

$sql = "select  statement";
$stmt = $db->prepare( $sql );
$stmt->execute();
$response = array();
$response["products"] = $stmt->fetchAll( PDO::FETCH_ASSOC );
$response["success"] = 1;
echo json_encode($response);

在php中循环througn mysql结果
