Question

我试图将这些数据提取到一个while循环中，并且根本没有返回任何内容，任何想法都错了吗？

代码：

<?php
if(isset($_GET['id'])){
    require('include/db.php');
    require('include/init.php');
    if(isset($_GET['id']) && is_numeric($_GET['id'])){
        $userid = $odb->real_escape_string($_GET['id']);
        $result3 = $odb->prepare("SELECT * FROM users where ID = :id");
        $result3->bindValue(":id", $userid);
        $result3->execute();
        while($row3 = $result3->fetch_array(MYSQLI_ASSOC)){
            $username=$row['username'];
            $email=$row['email'];
            $rank=$row['rank'];
            $membership=$row['membership'];
            $expire=$row['expire'];
            $status=$row['status'];
            echo "
            Username: ".$username."<br />
            Email: ".$email."<br />
            Rank: ".$rank."<br />
            Membership: ".$membership."<br />
            Expire: ".$expire."<br />
            Status: ".$status."<br />
            ";
        }
    } else {
        echo "You did not enter an ID!";
    }
?>

由于您使用的是PDO，因此必须更新某些功能。您可以准备并绑定值，而不是mysql_escape_string()，而PDO将逃避一切。另外，fetch_array()应为fetch()，MYSQLI_ASSOC应为PDO::FETCH_ASSOC。

<?php
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
if($id) {
    require('include/db.php');
    require('include/init.php');

    // Prepare && Binding will take care of escaping the string
    $result = $odb->prepare("SELECT * FROM users where ID = :id");
    $result->bindValue(":id", $id);

    $result->execute();
    while($row = $result->fetch(PDO::FETCH_ASSOC)) {
        $username = $row['username'];
        $email = $row['email'];
        $rank = $row['rank'];
        $membership = $row['membership'];
        $expire = $row['expire'];
        $status = $row['status'];

        echo "
        Username: ".$username."<br />
        Email: ".$email."<br />
        Rank: ".$rank."<br />
        Membership: ".$membership."<br />
        Expire: ".$expire."<br />
        Status: ".$status."<br />
        ";
    }
} else {
    echo "You did not enter an ID!";
}
?>

PDO在While循环中提取数据
