I am confused... This is a snippet of the PHP code you are trying to run? If 
so, then yes it probably has a problem. The "if()" statement is looking for a 
true/false or 0/non-0 result... giving it a string will likely confuse it.

My guess is that you are trying to say "if $currentWindDirection AND 
$currentWindSpeed exist"? If so then it should read:

if (isset($currentWindDirection) && isset($currentWindSpeed)) {
  do something
}
