A little php

Finally I got it
But one question: What is really calculated here, or in other words what does the php-solver do?

I think there is nothing special about the calculation.
It is a bit manipulation with xor [0].
10001101001110111 = 72311
10101110110110101 = 89525
00100011111000010 = 18370
[0]

I did this with Netbeans PHP application, but I was left curious, so I tried this with Python, and succeeded:
Code: Select all
#A little PHP
x = 72311
y = 89525
k = x ^ y
print k
Pretty simple imho, PHP is way more complicated, and this is alot simpler than that PHP one. Again, imo. But it was pretty simple. And I had neither no idea that I could just XOR it between the values.
This was a nice challenge, altho a hard one for those who might not have any experience in PHP;
How to install the environment aka XAMPP, NetBeans, etc.
Translating the code into Python would've been ever better if I was a first-timer in PHP and wouldn't have had the programs needed.

The PHP one was deliberately obfuscated. The only tricky part for me was remembering whether php used ^ for xor or exponentiation.
What about some useful

It is easy, you just have to know how to read an escaped PHP string. Then I just entered 72311^89525 in my JavaScript console, and copy-pasted the result.
