php - 回显 PHP 准备好的语句的最有效方法

Question

我有一个 SQL 查询，出于安全目的，我最近将其转换为准备好的语句。我有一个查询返回许多行，每行由许多列组成。我的问题是如何使用 while 循环回显结果。到目前为止我的例子:

$stmt = $conn->prepare("SELECT * FROM Customers 
                                  WHERE travel_Date >= ?
                                  AND   travel_Date <= ?
                                  ".$searchOption."
                                  LIMIT ? 
                                  OFFSET ?");
$todayDateFrom = $todayDate." 00:00:00";
$todayDateTo = $todayDate." 23:59:59";
$stmt->bind_param("ssii", $todayDateFrom, $todayDateTo, $limit, $offset);
$stmt->execute();

while ($stmt->fetch()) {
    //echo first name
    //echo surname
    //echo address
    //echo number
    //echo type
    //15 other things i need to print off
}

我不确定最好的方法是什么。我想过:

$stmt->bind_result($firstName, $surname, $address, //etc);

但我想知道是否还有另一种类似于未准备语句的替代方法:

while($row = mysqli_fetch_array($query)){
    echo $row['firstName'];
    echo $row['surname'];
    echo $row['address'];
    //etc
}

Answer 1

试试这个:

$result = $stmt->get_result();
    while ($row = $result->fetch_array())
    {
        echo $row['firstName'];
        echo $row['surname'];
        echo $row['address'];
    }
