I don't understand how the following declarations works, or what they mean. How is the notation $ProdID = $Order[0] ? $Order[0] : ""; read, or what does it mean?

This is just an easy and fast way to write an if/else statement. Syntax is as follows

($argument) ? 'true' : 'false';

So,

PHP Code:

//if $Order[0] returns true, set $ProdID to $Order[0], else set it as NULL;

$ProdID = ($Order[0]) ? $Order[0] : NULL; 



//Same as above

if($Order[0] != NULL)

  {

      $ProdID = $Order[0];

  }

else

  { 

      $ProdID = NULL;

  }
