Answer 1

Yes, fwrite function is limited to length, and for a large files you may split the file to a smaller pieces like the following:

    $file   = fopen("file.json", "w");

    $pieces = str_split($content, 1024 * 4);
    foreach ($pieces as $piece) {
        fwrite($file, $piece, strlen($piece));
    }

    fclose($file);
