<title>Question and Answer Read From Text File</title>

<body>
<form action="processor.php" method="POST" align="center">
<b><u> QUESTIONS AND ANSWERS QUIZ</u></b> <br /><br />
<?php
$openFile = fopen("questionandanswers.txt", "r") or exit ("unable to open the text file");
$string = fread($openFile, filesize("questionandanswers.txt"));
//Regex to get from the first number to the string's end, so we ignore the Number Question... bit;
preg_match('/\d.*/', $string, $match);
//We get all the strings starting with a number until it finds another number (which will be the beginning of another question;
preg_match_all('/\d\D*/', $match[0], $results);
$qas = array(); // We prepare an array with all the questions/answers
foreach($results[0] as $result){
//Separating the question from the string with all the answers.
list($question, $all_answers) = explode(':', $result);
//Separating the different answers
$answers_array = explode('.', $all_answers);
//Stuffing the question and the array with all the answers into the previously prepared array;
$qas[] = array('question' => $question, 'answers' => $answers_array);
}
//Looping through the array and outputting all the info into a form;
foreach($qas as $k=>$v)
{
echo "<input id='text_disabled' style='width:40%' type='text' value='".$v['question']."' name='questions[]' disabled>";
echo "<select name='selected_answers[]>";
foreach($v['answers'] as $answer){
echo "<option value='".$answer."'>".$answer."</option>";
}
echo "</select>";
echo "<br/><br/>";
}
?>
<input type="submit" value="Submit Answers"> <input type="reset" value ="Clear Answers">
</form>
</body>
</html>
Where could the problem be in my code?
