How to write data to a file with file_put_contents() without overwriting it?

I'm to create a txt file with a list of names, those names come from a form.

My logic goes as follows:

if ($_SERVER['REQUEST_METHOD'] == "POST") {
    $name = $_POST['username'];
}


function add_name($name, $file_name = "names.txt") {
    if(file_exists($file_name)) {
        $name = $name;
        file_put_contents($file_name, $name);
} else { 
         $handle = fopen($file_name, 'w+');
         fwrite($handle, $name);
         fclose($handle);
    }
}

Now problem is, it writes the name, however when I set another record, it deletes the previous, any help? maybe file_put_contents is not the right function to use?

If the file already exists, by default file_put_contents() would overwrite the existing file.

To prevent the current file from being overwritten, pass the FILE_APPEND flag as the function's third argument.

For example:

if (file_exists($file_name)) {
    file_put_contents($file_name, $some_value, FILE_APPEND);
} else { 
    //...
}
