(PHP 5, PHP 7, PHP 8)
variant_idiv — Converts variants to integers and then returns the result from dividing them
Converts left and right to
integer values, and then performs integer division.
leftThe left operand.
rightThe right operand.
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()。
