variant_div

(PHP 5, PHP 7)

variant_div — Returns the result from dividing two variants

说明

variant_div ( mixed $left , mixed $right ) : mixed

Divides left by right and returns the result.

参数

left

The left operand.

right

The right operand.

Note:

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()。

返回值
