PHP: Вывод и запись в файл построчно методом $_GET

Вывод:

$file_pointer = fopen("data.txt", "r");
$content = array();
while (!feof($file_pointer)) {
    $content[] = fgets($file_pointer);
}
foreach ($content as $item) {
    $row = explode("|", $item);
    echo 
    "<tr>
        <td>
            <img src='$row[4]' alt='$row[0]' />
        </td>
        <td>
            <p>$row[0]<p/>
            <p>$row[1]</p>
            <p>$row[3]</p>
            <p>$row[2]</p>
        </td>
    </tr>";
}
fclose($file_pointer);

Запись:

<?
if(isset($_GET["submit"])) {
    $game = trim($_GET["game"]);
    $price = trim($_GET["price"]);
    $year = trim($_GET["year"]);
    $plat = trim($_GET["plat"]);
    $img = trim($_GET["img"]);

    $input = "\n".$game."|".$year."|".$price."|".$plat."|".$img;
    $filePoitner = fopen("data.txt", "a+");
    fwrite($filePoitner, $input);
    fclose($filePoitner);
}
?>
