有没有办法在PHP中编写C＃操作符^ =

Question

I am converting a C# routine to php

do not understand how to do this C#

bool ret = false;

ret ^= (y * multiple[i] + constant[i] < x);

its the operator ^= ??

Answer 1

Short answer: in PHP you can use the same ^= operator.

The x ^= y is equivalent to x = x ^ y with ^ the bitwise xor operator.

In PHP ^ is also the bitwise xor operator. So it is the same in PHP, you can use:

$ret ^= ($y * $multiple[$i] + $constant[$i] < $x);

given of course that $y, $multiple, $i$, etc. all have an equivalent meaning.
