The two arrays does not compare and compute by adding one for every similar and 0 if otherwise I don't know what is wrong with the codes, but to me is seems fine. What might be the problem?
<html>
<head>
<title>Chosen answers</title>

<?php
//Posting of the chosen answers
$answers = $_POST['selected_answers'];
echo '<b><u>THE ANSWERS YOU HAVE CHOSEN ARE:</u></b><br /><br />';
print_r($answers);
//Opening of the answers file, reading and printing it
$openFile = fopen("answers.txt", "r") or exit ("unable to open the answers file");
$fileContents = fread($openFile, filesize("answers.txt"));
fclose($openFile);
$delimiter = " ";
$myArray = explode($delimiter, $fileContents);
$score = $score1 = $score2 = $score3 = $score4 = $score5 = $score6 = $score7 = $score8 = 0;
//Computation of marks scored for the answered questions
if ($answers[0] == $myArray[0])
{
$score = 1;
}
if ($answers[1] == $myArray[1])

$score1 = 1;
