variant_or — Performs a logical disjunction on two variants
Performs a bitwise OR operation. Note that this is slightly different from a regular OR operation.
left
The left operand.
right
The right operand.
注意:
对于所有变量运算函数,本函数的参数可以是 PHP 内置的类型(整数,字符串,浮点数,布尔型或者
null
),或者是一个 COM,VARIANT 或者 DOTNET 类的实例。PHP 内置类型将会使用和构造variant类相同的规则转换成变量。COM 和 DOTNET 对象的值将会取其默认属性并被当成变量值使用。变量运算函数是同名函数在 COM 库中的外包;有关此类函数的更多信息参见 MSDN 库。PHP 函数命名有少许区别,例如 PHP 中的 variant_add() 对应于 MSDN 文档中的
VarAdd()
。
If left is |
If right is |
then the result is |
---|---|---|
true | true | true |
true | false | true |
true | null | true |
false | true | true |
false | false | false |
false | null | null |
null | true | true |
null | false | null |
null | null | null |
Throws a com_exception on failure.
