    Hi

    Im having a problem writing a php code for a course im taking. We have to make a star rating widget that saves the ratings in a text file. What I got so far is that the ratings is being saved in a text file with each rating on a single row. Now I have to take the numbers in that text file and display the number of votes and the averages sum of the ratings. And I don't know were start can someone please help me?

    this is the code i have so far in the php file.


    <?php
$score = $_POST['score'];
$pid = $_POST['pid'];


$file = fopen("rating.txt", "r") or exit("Unable to open file!");

if(isset($_POST['score']) && isset($_POST['pid'])) {
    $data = $_POST['score'] . "\r\n";
    $ret = file_put_contents('rating.txt', $data, FILE_APPEND | LOCK_EX);
    if($ret === false) {
        die('There was an error writing this file');
    }
    else {
        echo "$ret bytes written to file";
    }
}
else {
   die('no post data to process');
}


$files = file("rating.txt");
