What is the difference between XOR operators in php and perl?

Question

Perl

Can you please tell me what is the difference between bitwise exclusive or in PHP and PERL and how can you reproduce the operation of this operator in Perl using php?
Porting the following code from perl to php, getting different results with the same input.
$test = ($password ^ $newchal);
UPD: for some reason in php it returns a string 2 times shorter than in perl and the beginning of the perl string matches the one returned by PHP
UPD: I read in the dock that pearl, if 2 arguments in ^ are of different lengths, the short value is filled with zero bits , now the question. I know what value I have is short, how can I add these zero bits to it?

Answer 1

They should work the same way (as they do in many other languages). If not, look at the variables themselves, they do not match in different code

Answer 2

Check the types of variables.

Answer 3

In both php and perl this is the same: xor It's
just that perl doesn't forgive mistakes =)
