variant_cat

(PHP 5)

variant_cat — concatenates two variant values together and returns the result

Description

mixed variant_cat ( mixed $left , mixed $right )

Concatenates left with right and returns the result.

See also 字符串运算符 for the string concatenation operator; this function is notionally equivalent to $left . $right .

Note: 对于所有的变量算法函数,此函数的参数可以要么是 PHP 自身的类型(整型,字符串,浮点型,布尔型或者 NULL),要么是一个 COM,VARIANT 或 DOTNET 类的实例。PHP 自身类型将被转换为变量,使用与 VARIANT 类的构造函数中相同的规则。COM 和 DOTNET 对象将具有其默认属性的值,取得并作为变量值使用。
变量算法函数是 COM 库中与其名称接近的函数的封装。此类函数的更多信息请参考 MSDN 库。PHP 函数命名有少许不同,例如 PHP 中的 variant_add() 对应于 MSDN 文档中的 VarAdd()。
