请看看这个:
$str = '¡hola!'; // '¡' is the spanish opening exclamation mark
echo $str{0}; // prints nothing
echo $str{1}; // prints �
echo $str{2}; // prints h
php脚本使用UTF-8编码,我执行它时得到的结果与apache模块或CLI相同。PHP版本: 5.4.6
为什么我会得到这么奇怪的结果?
在Protobuffers文档中,已经给出了
"For historical reasons, repeated fields of basic numeric types aren't encoded as
efficiently as they could be. New code should use the special option [packed=true] to get
a more efficient encoding. For example:
repeated int32 samples = 4 [packed=true];"
有人能清楚
我不能让它正常工作。
#include <windows.h>
int main()
{
DWORD i = 6521;
BYTE first = i >> 32;
BYTE second = i >> 24;
BYTE third = i >> 16;
BYTE fourth = i >> 8;
i = (((DWORD)fourth) << 24) | (((DWORD)third) << 16) | (((DWORD)second) <<
