Question

我正在尝试在实时服务器上执行以下操作，但它不会执行。在当地主机上一切都很好。我能够在实时服务器上执行其他sop>

$mysqli = new mysqli("localhost", "username", "password", "database");

if(isset($_POST['username'])&& isset($_POST['password']) ){
    $username =$_POST['username'];
    $password =  md5($_POST['password']);
    if ($mysqli) {
        /* Prepared statement, stage 1: prepare */
        if (!($stmt = $mysqli->prepare("select acc.accountId, acc.firstname, prof.imagename      from accounts acc inner join profilepicture prof on prof.accountId=acc.accountId where acc.emailAddress=(?) and acc.password=(?)"))) {
             echo "Prepare failed: (" . $mysqli->errno . ") " . $mysqli->error;
        }
        /* Prepared statement, stage 2: bind and execute */
        $stmt->bind_param("ss", $username,$password);
        $stmt->execute();
        $result = $stmt->get_result();
        $row = $result->fetch_assoc();
        if(!empty($row)){
            `enter code here`
            `enter code here`// STATEMENTS TO EXECUTE IF DETAILS EXISTS
        }

Answer 1

这可能是原因：您正在登录没有默认数据库，没有用户名和密码的mysql

$mysqli = new mysqli("localhost", "", "", "");

应该是这样的：

$mysqli = new mysqli("localhost", "user", "password", "database");

在实时服务器或cpanel中..转到mysql部分创建数据库和用户及密码...并授予该用户编辑更新和删除的权限..然后在

$ mysqli = new mysqli（＆＃34; localhost＆＃34;，＆＃34;＆＃34;，＆＃34;＆＃34;，＆＃34;＆＃34;）;

添加所有三个用户名密码和数据库名称..然后..它将正常工作.. 希望它有效
