将PHP用户输入与mysqli数据库进行比较

I'm creating an online test. I have the form's and everything set out correctly and it send an email to the admin nicely. However I want it to do this:

I need the script to compare the results with data that is already in the MySQL database, so if question 1 was: "Complete the sentence: We took the dog for a __" and then they answer with "walk", then it will send the answer and weather it is correct in an email like: 1) walk - Correct

Here is the script I have(all the a1,a2, ect... are the answers.):

<?php
$con=mysqli_connect("mywebsite.com","username","password","eiy_testResults");
if (mysqli_connect_errno($con))
  {
  echo "ERROR - Failed to connect to MySQL Server. Please contact an administrator: " . mysqli_connect_error();
  }


$emailSubject = 'Online Test results';
$webMaster = 'name@email.com';



$name = $_POST['name'];
$email = $_POST['email'];
$date = $_POST['date'];
// Questions in order. Ad more changing the number (+1).
$a1 = $_POST['a1'];
$a2 = $_POST['a2'];
$a3 = $_POST['a3'];
$a4 = $_POST['a4'];
$a5 = $_POST['a5'];
$a6 = $_POST['a6'];
$a7 = $_POST['a7'];
$a8 = $_POST['a8'];
$a9 = $_POST['a9'];

    The following code stub should do your comparing for you. I have not tested this code with a database, but from what I can see it ought to work. It's a bit rough and ready but I've kept it simple so you should be able to follow it:

    //Set variables to hold output data and total score.

$output="";
$score=0;

//for-next loop.  This means "Set n to value one.  Every time through the loop (between {}) increase n by one.  Do this while n is less than or equal to 50"

for($n=1;$n<=50;$n++)
    {
    $sql="SELECT answer FROM table WHERE answernumber='a$n'";  //sql is specific to your table of course - you will need to change this.
    $result = $con->query($sql); // perform the query
    $row = $result->fetch_assoc();  //load the result into the array $row
    $key="a".$n;                     //concatenate to generate the $_POST keys
    if($row['answer']==$_POST[$key]) //compare the data from the table with the answer
        {
        //answer is correct
        $score++;
        $output.="Answer $n is correct</BR>"; //add responses to the output string
        }
        else
        {
        $output.="Answer $n is incorrect</BR>";
        }
    }
$output.="Total score: $score/50";  //add the score
echo $output;  //echo to screen.
