PHP hello world obfuscation contest - meow - 05-02-2016
Title says it all, create an obfuscated PHP script that simply prints "hello world" (case doesn't matter). The objective is to make it look at confusing as possible.
Rules:
No encrypting, encoding (base64 and whatnot), hashing, etc.
No redundant code like comments or x+1-1+1-1 etc
Here's what I was able to come up with in an hour or so, I even ended up confusing myself near the end, but I got it to work. It just prints "hello world" -
PHP Code:
@$_["\x68"]=chr(ord("\x68")).chr(ord("e")).chr(104)."\x6C".chr(108)."\x2F"."\x52".chr(111).chr(108)."\x20";@$___=$_["h"];@$__[1]=$_[chr(104)][0x0+(0*0)-50+(25*(sqrt(4)))].$___[(int)"\x37"];@$__[0x02]=$___[0x0+(sqrt(sqrt(81)))].$_[chr(54+(10*(sqrt(25))))][1].$_["h"][count($_["\x68"])-2]."\x20";@$_["\x77"]=chr(119)."\x6F"."\x72"."balls".chr(108)."\x64"."\x6C".chr(126)."\x2F"."\x52".chr(ord("\x6F"));@$_["lol"]=$_[chr(69+(5*(sqrt(100))))][0].$_["h"][count($_["\x68"])+6].$_[chr(119)][sqrt(16)/2].$_["\x68"][count($_[chr(104)])+3]."\x64";printf($__[sqrt(1)][0].$__[sqrt(4)][1*1].$__[5%3][count($__[(int)"\x32"])-1].$__[(2378420%2)+2][0].$__[9%4][count($__[1])]."\x20".$_["lol"]."\xA");

Seriously? No one's even going to try to make one harder than mine?
All I did was use (hexa)decimal and math to make it look more complicated.. there are WAY more things you could do to make it look better than mine.

Now that activity has boosted, I'd like to see if there's anyone from the newly merged forum that would like to take a swing at this.

Wow I totally missed your post on this on the first.
I'll try this over the weekend when I have more time. I'm consumed with finals right now. Putting this in my TODOlist so I don't forget,
