I'm making a program that will alphabetize lines of a text file (jigglypuff.txt)
And for some reason whenever I use it the file just becomes blank...

CODE
$gamelist = fopen("jigglypuff.txt", 'r');
    flock($gamelist, LOCK_SH);
    while (!feof($gamelist)) {
        $data = fgets($gamelist, 500);
        $i = 0;
        $games[$i] = $data;
        $i++;
    }
    flock($gamelist, LOCK_UN);
    fclose($gamelist);
    
    sort($games);
    $gn = count($games);
    
    $gamelist = fopen("jigglypuff.txt", 'w');
    flock($gamelist, LOCK_EX);
    for($i = 0; $i <= $gn; $i++) {
        fwrite($gamelist, $games[$i]);
    }
    flock($gamelist, LOCK_UN);
    fclose($gamelist);


Any help would be greatly appreciated!

CODE

    while (!feof($gamelist)) {
        $data = fgets($gamelist, 500);
        $i = 0;
        $games[$i] = $data;
        $i++;
    }


Initialize the $i variable outside of the while loop. If you set it to zero before you set the data, you'll overwrite array element zero everytime, & nothing else will get set.

CODE

$i = 0;
....
    while (!feof($gamelist)) {
        $data = fgets($gamelist, 500);
        $games[$i] = $data;
        $i++;
    }
