[php] php MD5 generates only one hashed output

[Michael Greenhill]

For a start, I'd use file_put_contents() instead of the clunky fopen()
handle.

If you want to append the text file instead of overwriting it (as your code
seems to hint at) look at this option:

// Find the passwords we already have saved
$fcontents = file_get_contents("/path/to/file.txt");

// Append the new password to the start of the list
file_put_contents("/path/to/file.txt", $storedpass."\r\n".$fcontents);
