(PHP 5, PHP 7, PHP 8)
variant_fix — Returns the integer portion of a variant
valueThe variant.
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(lèi)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(lèi)的實(shí)例。PHP 內(nèi)置類(lèi)型將會(huì)使用和構(gòu)造variant類(lèi)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(kù)中的外包;有關(guān)此類(lèi)函數(shù)的更多信息參見(jiàn) MSDN 庫(kù)。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 is negative, then the first negative
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.
