PHP和JS的按位运算不同 [英] Bitwise operations PHP and JS different

问题描述

为什么php和js对同一件事给出不同的结果:JS:

Why does php and js give different results to the same thing: JS:

1085 << 24 = 1023410176

PHP:

1085 << 24 = 18203279360

推荐答案

JavaScript中按位运算的操作数始终被视为int32，而在PHP中并非如此.

The operands of a bitwise operation in JavaScript are always treated as int32, and in PHP this is not the case.

在PHP中，这些位不会被截断，因为它不会被视为32位整数.

And in PHP, the bits do not get truncated because it is not treated as a 32-bit integer.
