Question

我有一个问题是让我的php测验将用户的成绩写入单独的文件。它显示了他们有多少是正确/错误但它没有写入文件。我的代码在这里有什么问题可以防止这种情况，或者我错过了什么？一些有建设性的意见会有所帮助。

<?php
session_start();
#error_reporting(E_ALL); ini_set('display_errors', 1);
require_once('connect.php');
require_once "lib.php";
require_once "utils.php";
$quiz_done = true;
if(isset($_SESSION['active']))
{
    $EmailAddress = $_SESSION['EmailAddress'];
    $sql="SELECT * FROM users WHERE EmailAddress='$EmailAddress'";

    if($Results = mysqli_query($link, $sql))
    {
        while($row = mysqli_fetch_array($Results, MYSQLI_ASSOC))
        {
            $UserID = $row['UserID'];
            $_SESSION['UserID'] = $UserID;
        }
    }
    echo $UserID;
    $sql1="SELECT * FROM Quiz WHERE UserID='$UserID'";
    $result1 = mysqli_query($link, $sql1);
    if($result1)
    {
        while($record = mysqli_fetch_row($result1))
        {
            if($record == $UserID)
            {
                $quiz_done=true;                    
                $sql="DELETE FROM Quiz WHERE UserID='$UserID'";
                $Results = mysqli_query($link, $sql);
            }
            else
            {
                $quiz_done=false;                   
            }
     }
    }
}
else
{
    header("Location: login.php");
}

在那里甚至没有写文件。我会调查

public function writeGrade(){
        $content  = "".$userid." Results";
        $content .= "".$YourGradeVariable."";
        $content .="\r\n";
        $fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/".$userid.".txt","wb");
        fwrite($fp,$content);
        fclose($fp);
    }

这很普遍，但你应该能够自定义它以满足你的需求。

我的php测验不是将用户的成绩写入单独的文件。我不确定我是否正确行事
