注意:
對(duì)于所有變量運(yùn)算函數(shù),本函數(shù)的參數(shù)可以是 PHP 內(nèi)置的類型(整數(shù),字符串,浮點(diǎn)數(shù),布爾型或者
null
),或者是一個(gè) COM,VARIANT 或者 DOTNET 類的實(shí)例。PHP 內(nèi)置類型將會(huì)使用和構(gòu)造variant類相同的規(guī)則轉(zhuǎn)換成變量。COM 和 DOTNET 對(duì)象的值將會(huì)取其默認(rèn)屬性并被當(dāng)成變量值使用。變量運(yùn)算函數(shù)是同名函數(shù)在 COM 庫中的外包;有關(guān)此類函數(shù)的更多信息參見 MSDN 庫。PHP 函數(shù)命名有少許區(qū)別,例如 PHP 中的 variant_add() 對(duì)應(yīng)于 MSDN 文檔中的
VarAdd()
。
If value

integer greater than or equal to the variant is returned, otherwise
returns the integer portion of the value of
value
.
Throws a com_exception on failure.
