Okay so I can't seem to find anything definitive on the subject. Really my needs are pretty simple. I am using PHP5/SOAP to call a remote web service on a box hosted by a 3rd party. I have no problem ...
1. Multiplying one byte by 256 then ORing it with the low order byte. 2. Bit shift the high byte and OR it with low order byte. Which is faster and is there a better way?
