要使PHP版本的按位异或(Bitwise XOR)操作与JavaScript版本匹配,首先需要了解这两种语言中按位操作的基本概念和差异。 基础概念 按位异或(XOR)是一种二进制运算,对于两个位,如果两个位相同,则结果为0,如果两个位不同,则结果为1。在PHP和JavaScript中,按位异或操作符都是^。
JavaScript Bitwise XOR When a bitwise XOR is performed on a pair of bits, it returns 1 if the bits are different: One bit example: OperationResult 0 ^ 00 0 ^ 11 1 ^ 01 1 ^ 10 4 bits example: OperationResult 1111 ^ 00001111
Bitwise XOR Operator (^) in JavaScript The bitwise XOR Operator (^) in JavaScript compares each binary bit pair and sets a1bit in that position when only one of those bits is1. If both bits are1, then the XOR operator will return0for that position, hence why it’s called eXclusiveOR....
^ Bitwise XOR Returns 1 if both bits are different, otherwise 0. ! Bitwise NOT Returns 1 if bit is 0, otherwise 0. << Left Shift Shifts the bits left by pushing zeros in from right and discarding leftmost bits. >> Right Shift Shifts the bits right by pushing copies of leftmost bit ...
XOR (exclusive or) is a bitwise operator that compares two values bitwise and returns a new value with a 1 in each bit position where the corresponding bits of the original values are different, and a 0 where they are the same. Let's say we have two numbers: 6 and 5. Their binary ...
