复制代码 代码如下:
/******************************************************
* 逐bit的低位在前算法
* @param $x
* @return int
*/
function reverse($x)
{
$result = 0;
for($i = 0; $i {
$result = ($result > $i));
}
return $result & 0xff;
}
调用展示：
复制代码 代码如下:
$testData = 0xC5; //二进制：1100 0101
$testRet = reverse($testData);
echo $testRet; //输出值为163，二进制为1010 0011
