http_build_query replaces array key in result

Question

I'm trying to use http_build_query and it's returning an unexpected string. Here's an example of what I'm doing:

$timestamp = time();

$args = array("name"=>"Bob",
              "id"=>uniqid(),
              "timestamp"=>$timestamp,
              "token"=>md5('unique_salt' . $timestamp));

$query = http_build_query($args, '', '&');

echo $query;

And this is the result:

name=Bob&id=5354a8336b3d7×tamp=1398057011&token=ba2c56005ac83d5169d173993f6a0d32

You can see that the key "timestamp" has been replaced with "×tamp" - I'm not even sure what that first character is because it is not the letter x.

I've tested this on several different servers with the same result. What gives?!

Try to explore page source of output.

That's because in HTML &times translates to the multiplication sign; this is why you should escape HTML output.

echo htmlspecialchars($query, ENT_QUOTES, 'UTF-8');
