Read/download large file in PHP without running out of memory

Question

How can I read/download a large file in PHP without running into allowed memory bytes exhausted?

I am currently trying:

$content = null;
while (!feof($file['data'])) {
    $content .= fread($file['data'], 8192);
}

header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=\"" . $file['real_filename'] . "\"");
header("Content-Length: " . $file['length']);

echo $content;

Have you tried this ?

header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=\"" . $file['real_filename'] . "\"");
header("Content-Length: " . $file['length']);

while (!feof($file['data'])) {
    print fread($file['data'], 8192);
}
