About Rules for Homework & Coursework Questions Forum
Hi, in my case, I have a question for topics that are slightly dealt with in class, which I am investigating on my own but which are not directly related to the lessons.
Do I have to put the name of the school and others?
(I can't put the name of the professor because is against the school rules to share private details of person related to the school, which includes the name)

LEARN ABOUT PHP
variant_and
VARIANT_AND(3) 1 VARIANT_AND(3)
variant_and - Performs a bitwise AND operation between two variants
SYNOPSIS
mixed variant_and (mixed $left, mixed $right)
DESCRIPTION
Performs a bitwise AND operation. Note that this is slightly different from a regular AND 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.
