Question

我并不是真的想做多少，我试图检查变量是否匹配表中的值，如果是，它会增加存储在$ mark中的值。

即。 2/5正确的测验给出$ mark值40。

目前，它的作用是输出，即使检查“应该”失败，它的值为100。

如果有人可能告诉我我是如何搞砸的话，我会很感激。：d

我试图计算的PHP页面。

<?php
error_reporting(E_ALL); 
ini_set('display_errors', 1); 
include ("dbfunctions.php");


//print first part of html
?>
<!DOCTYPE html>
<html>
<head>  
<meta charset="UTF-8" /> 
<title>Results</title>  
</head>
<body>
<h1>Results</h1>


<?php
//retrieve username and password
$username = "username";
$password = "password";

//connect to database
$dbConn = dbConnect("$username", "$password") ;
dbSelect($dbConn, "$username");

//retrieve pet and number of tins from the form
$question1 = $_POST['question1'];
$question2 = $_POST['question2'];
$question3 = $_POST['question3'];
$question4 = $_POST['question4'];
$question5 = $_POST['question5'];
$mark=0;

$query = "SELECT * FROM footballdb_prototype";
$result = runQuery($dbConn, $query);
if($numrows = mysqli_num_rows($result)){
    if ($numrows == 0)
    {
   print "<p>There was nothing in the table</p>";   
   print "</body>";
   print "</html>";
   exit();
   }
echo("some results");

//check to see if answer matches database
while($row = mysqli_fetch_assoc($result)) {
   if ("SELECT * FROM footballdb_prototype WHERE '$question1' = question1"){
        $mark += 20;
        }
    if ("SELECT * FROM footballdb_prototype WHERE '$question2' == question2"){
        $mark += 20;
        }
    if ("SELECT * FROM footballdb_prototype WHERE '$question3' == question3"){
        $mark += 20;
       }
    if ("SELECT * FROM footballdb_prototype WHERE '$question4' == question4"){
        $mark += 20;
       }
    if ("SELECT * FROM footballdb_prototype WHERE '$question5' == question5"){
        $mark += 20;
       }

    }
}
else {
echo "we fucked";
}


echo "<p>You scored $mark %";
mysqli_close($dbConn);
?>
