注意:
對于所有變量運算函數，本函數的參數可以是 PHP 內置的類(lèi)型（整數，字符串，浮點(diǎn)數，布爾型或者
null），或者是一個(gè) COM，VARIANT 或者 DOTNET 類(lèi)的實(shí)例。PHP 內置類(lèi)型將會(huì )使用和構造variant類(lèi)相同的規則轉換成變量。COM 和 DOTNET 對象的值將會(huì )取其默認屬性并被當成變量值使用。變量運算函數是同名函數在 COM 庫中的外包；有關(guān)此類(lèi)函數的更多信息參見(jiàn) MSDN 庫。PHP 函數命名有少許區別，例如 PHP 中的 variant_add() 對應于 MSDN 文檔中的
VarAdd()。
