C++需要實(shí)現(xiàn)PHP端的:
bin2Hex函數(shù),PHP通過(guò)這種類(lèi)型的字符串調(diào)用:pack轉(zhuǎn)換成PHP能識(shí)別的2進(jìn)制數(shù)據(jù)。 C++需要做的是實(shí)現(xiàn)一個(gè)bin2hex,其實(shí)只是把c++讀取的2進(jìn)制數(shù)據(jù)當(dāng)成byte數(shù)組,把每一位轉(zhuǎn)換成16進(jìn)制字符串就可以了。Qt中使用sprintf無(wú)法限制2位長(zhǎng)度,因此sprintf之后判斷長(zhǎng)度為8則截取最后3個(gè)字符串，包含了/0終止符#ifndef PHPCLASS_H
