Using php: // memory covers causes errors

I am trying to extend the PHP mailer class from Worx by adding a method that allows me to add attachments using string data, rather than the file path.

I came up with something like this:

public function addAttachmentString($string, $name='', $encoding = 'base64', $type = 'application/octet-stream')
{
  $path = 'php://memory/' . md5(microtime());
  $file = fopen($path, 'w');
  fwrite($file, $string);
  fclose($file);

  $this->AddAttachment($path, $name, $encoding, $type);
}

However, all I get is a PHP warning:

PHP Warning:  fopen() [<a href='function.fopen'>function.fopen</a>]: Invalid php:// URL specified

There are no decent examples with the original documentation, but I found a couple on the Internet (including one here on SO ), and my usage is displayed according to them.

Has anyone had success using this?

    fclose($file);
}
print "done - with md5\n";

print "Trying without md5\n";
$path = 'php://memory';
$file = fopen($path, 'w');
if ($file)
{
    fwrite($file, "blah");
    fclose($file);
}
print "done - no md5\n";
