COM_ISENUM(3) 1 COM_ISENUM(3)com_isenum - Indicates if a COM object has an IEnumVariant interface for iteration [deprecated]
SYNOPSIS
bool com_isenum (variant $com_module)
DESCRIPTION
Checks to see if a COM object can be enumerated using the Next() method hack. See "COM" class for more details on these methods.
PARAMETERS
o $com_module
- The COM object.
RETURN VALUES
Returns TRUE if the object can be enumerated, FALSE otherwise.
NOTES
Note
This function does not exist in PHP 5; use the more natural foreach statement to iterate over the contents of COM objects. See "For
Each" for more details.

VARIANT_IMP(3) 1 VARIANT_IMP(3)variant_imp - Performs a bitwise implication on two variantsSYNOPSIS
mixed variant_imp (mixed $left, mixed $right)
DESCRIPTION
Performs a bitwise implication 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.
