You will have to keep track of the last index used, whichever method you use. What's the reason for using a string like that?

This was what guided my text file:

The questions will be finished with a colon(:).
The answers will be finished with a dot(.), all of them but the last one, as we will use the number of the question as separator.
The questions or answers won't contain any numbers [0-9] or it will confuse the regex.

How will I be able to implement the substr() and strpos(() based on my research for the last 2 hours they deal with characters only.

How will I implement the above mention function in the following and do away with the

fread ()

fucntion and introduce

fget ()

That reads line by line.
Actually hre is my regex code:

$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);

$qas = array(); // We prepare an array that will store the questions/answers
foreach($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);

    //removes unnecesary spaces in the questions

    $answers_array_trimmed = array_map('trim', $answers_array);

    //Storing 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;

$questionNr = 0;    
foreach($qas as $k=>$v)
    {
    echo "<input id='question{$questionNr}' style='width:40%' type='text' value='".$v['question']."' name='questions[]' >";
    echo '<br /><br />';
//Puts the answers of each question unique and in the form of radios
    foreach($v['answers'] as $answer)
        {
        echo "<input type=\"radio\" name=\"selected_answers[$questionNr]\" value=\"$answer\" />";
        echo "$answer";
        echo '<br/><br />';
        }
    $questionNr++;
    }
?>
<input name= "submit" type="submit" value="Submit Answers">&nbsp <input type="reset" value ="Clear Answers">
</form>
