">>>" command in Flash?

[Azu]

What does the >>> command do in Flash? And what is the PHP equivalent (putting >>> in PHP gives "Parse error: syntax error, unexpected '>'")?

I'm trying to reverse engineer the imeem swf player and this command is used 21 times in it.

Example usage;

        public function tea_code(arg1:*, arg2:*):*
        {
            var loc3:*;
            var loc4:*;
            var loc5:*;
            var loc6:*;
            var loc7:*;

            loc3 = arg1[0];
            loc4 = arg1[1];
            loc5 = 0;
            loc6 = 32;
            while (loc6-- > 0) 
            {
                loc3 = loc3 + ((loc4 << 4 ^ loc4 >>> 5) + loc4 ^ loc5 + arg2[(loc5 & 3)]);
                loc3 = loc3 | 0;
                loc5 = (loc5 = loc5 - 1640531527) | 0;
                loc4 = (loc4 = loc4 + ((loc3 << 4 ^ loc3 >>> 5) + loc3 ^ loc5 + arg2[(loc5 >>> 11 & 3)])) | 0;
            }
            (loc7 = new Array())[0] = loc3;
            loc7[1] = loc4;
            return loc7;
        }

P.S. how would I go about searching for >>> in Google? It says "Your search - >>> - did not match any documents." when I try to search for it.

Bitwise shift operators

The bitwise shift operators take two operands and shift the bits of the first operand to the extent specified by the second operand. All the bitwise shift operators, as listed in the following table, have equal precedence:

Operator


Operation performed
<<

Bitwise left shift
>>

Bitwise right shift
>>>

Bitwise unsigned right shift

Thank you.

So I'm guessing there is no equivalent in PHP, since PHP doesn't have unsigned integers?
I'll have to try to implement some kind of hacky work around that will probably be a lot slower then a normal bitwise operator?

There may be a PHP function for bitwise operations. You'd have to look.

Thanks for the tip, I already tried that though.

There are << and >> but those are differant form <<< and >>>

x=int(x/2^y) would **** it right y amount. I dont know if thats what the unsigned right shift **** does, really I havent used it.
