Update:
I have the 'rough TRUE / FALSE' API working and the initial test questions are now live on the site, alternating between the Open Trivia DB and our Forum Trivia DB (currently using a simple random number 0 or 1 to select).
Now need to add at least 95 more TRUE / FALSE questions

LEARN ABOUT PHP
variant_or
VARIANT_OR(3) 1 VARIANT_OR(3)
variant_or - Performs a logical disjunction on two variants
SYNOPSIS
mixed variant_or (mixed $left, mixed $right)
DESCRIPTION
Performs a bitwise OR operation. Note that this is slightly different from a regular OR operation.
PARAMETERS
o $left
- The left operand.
o $right
- The right operand.
Note
As with all the variant arithmetic functions, the parameters for this function can be either a PHP native type (integer, string,
floating point, boolean or NULL), or an instance of a COM, VARIANT or DOTNET class. PHP native types will be converted to variants
using the same rules as found in the constructor for the "VARIANT" class. COM and DOTNET objects will have the value of their
default property taken and used as the variant value.
The variant arithmetic functions are wrappers around the similarly named functions in the COM library; for more information on
these functions, consult the MSDN library. The PHP functions are named slightly differently; for example variant_add(3) in PHP cor-
responds to VarAdd() in the MSDN documentation.
