    Please how to achieve that emails are added to the file one per line, not appending all on one line?

    my current code:
    // input one email
email = $_POST['email'];
$stuff = serialize($email);
$handle = fopen('email_list.txt','w+');
fwrite($handle, $stuff);

// print all emails
$contents = unserialize(file_get_contents('email_list.txt'));
echo $file_contents;
    PHP:
    i tried like:
    fwrite($handle, $stuff . "\n");
    or
    $stuff = serialize($email) . "\n\r";

    but none works :(

    I'm not sure what benefit there is in serialising in the text document but this is what I'd do.

    // input one email
$email = myValidateEmailFunction($_POST['email']);
if ($email){
   $handle = fopen('email_list.txt','w+');
   fwrite($handle, $email . "\n");
}
// print all emails
$contents = file_get_contents('email_list.txt');
echo nl2br($file_contents);
    PHP:
    If you need to serialise then you need to unserialise on a line by line basis.

    You can simply do it like this:
    
// input one email
$email = (isset($_POST['email']) ? $_POST['email'].PHP_EOL : '');

$handle = fopen('email_list.txt','a');
fwrite($handle,$email);

// print all emails
foreach (file('email_list.txt') as $key => $value) {
   echo $value.'<br>';
}
