Base 64 to Binary then flip parts of the Binary to real numbers

[Headchopperz]

hey

im working on a problem and i cant fix it

http://forum.thegamecreators.com/?m=forum_view&t=143736&b=20

 

that is a lnk where i piuut a very detailed review on what i am stuck on

 

ill go over it quickly

in guild wars you get a code in BASE 64 and i need to convert it into Binary

i explain on the other forums that every certain amount of number of digits i need together

then i flip them

eg 0110 1101 becomes 0110 1011

then i do more flipping etc and at the end i convert the binary to real numbers

like 0011 is 3 and then using the numbers i find out the spell etc

 

ive already done this by hand as shown on that link i just dont know how to get it working with PHP

if java works with PHP which im sure it does than i dont mind it being in JAVA if its easier

 

ty for your time

 

[RussellReal]

base_convert

 

and to "flip" the numbers you could simply use array_walk on your exploded string

 

for example

<?php
function flipele(&$ele) {
$z = '';
for ($i = 0; ($a = $ele{$}) !== false; $i++) {
	$z = $a.$z;
}
$ele = $z;
}
$string = "0110 1011";
$arr = explode(" ",$string);
array_walk($arr,"flipele");
print_r($arr);
?>

i ran ur code and visually it does nothing

[Headchopperz]

Parse error: syntax error, unexpected '}', expecting T_VARIABLE or '$' in /home/danmake/public_html/outscape.org/test/index.php on line 4

 

i get that now =S

[RussellReal]

the script I provided I have tested personally, and it works

[Headchopperz]

why am i getting this error

i have PHP 5

[Headchopperz]

heres the prove

http://www.outscape.org/test/

[RussellReal]

show me the code of

 

home/danmake/public_html/outscape.org/test/index.php

[RussellReal]

oooh I'm sorry!!! lol

 

I tested it then edited it and I messed it up

 

<?php
function flipele(&$ele) {
$z = '';
for ($i = 0; ($a = $ele{$i}) !== false; $i++) {
	$z = $a.$z;
}
$ele = $z;
}
$string = "0110 1011";
$arr = explode(" ",$string);
array_walk($arr,"flipele");
print_r($arr);
?>

 

there use that bro I'm sorry

[Headchopperz]

Fatal error: Maximum execution time of 30 seconds exceeded in /home/danmake/public_html/outscape.org/test/index.php on line 4

it obviously doesnt like me lol

[RussellReal]

I'll test it again bro.. lol

[RussellReal]

<?php
function flipele(&$ele) {
	$z = '';
	for ($i = 0; ($a = substr($ele,$i,1)) !== false; $i++) {
		$z = $a.$z;
	}
	$ele = $z;
}
$string = "0110 1011";
$arr = explode(" ",$string);
array_walk($arr,"flipele");
print_r($arr);
?>

[Headchopperz]

sweet ty dude

lol that was quite funny

it works now tyvm

[GingerRobot]

Just fyi: there's already a function to reverse a string - strrev

[RussellReal]

wow

[Headchopperz]

would i use these

http://uk.php.net/base64_decode

base64 - binary

 

http://uk.php.net/manual/en/function.trim.php

or something better to remove all spaces in the binary

 

http://uk.php.net/manual/en/function.wordwrap.php

to count the amount of numbers and save into a new string

 

http://uk3.php.net/strrev

reverse the string

[Headchopperz]

or

http://uk.php.net/manual/en/function.substr.php

[Headchopperz]

<?php

$original = '00111010000001000100010101110000101101001001100110100000

10100110110001000011100110000110010001010110111100001011

10100000110100010111010001000100101001110000011010001001';

$neworiginal = substr($original,0,4)

$neworiginal = strrev($neworiginal)

$neworiginal = trim ( $neworiginal)

echo $original

echo $neworiginal

?>

 

code ive been trying

[RussellReal]

<?php
function zwalk(&$element) {
	$element = strrev($element);
}
$original = '0111001101101101';
$originalArray = explode(' ',trim(chunk_split($original,4,' ')));
array_walk($originalArray,'zwalk');
print_r($originalArray);
?>

[Headchopperz]

after its fliped i need all the bits back together

like 11001011

fliped = 0011 1101

then i need it to be = 00111101

 

<?php

function zwalk(&$element) {

$element = strrev($element);

}

$original = '00111010000001000100010101110000101101001001100110100000

10100110110001000011100110000110010001010110111100001011

10100000110100010111010001000100101001110000011010001001';

$oldarray = $originalArray;

$originalArray = explode(' ',trim(chunk_split($original,6,' ')));

$originalArray = $originalArray.$oldarray;

array_walk($originalArray,'zwalk');

print_r($originalArray);

print_r($oldarray);

?>

 

that doesnt work ><

[Headchopperz]

i made a working code but it needs arrays implemented  cos its like loads of code xD

 

<?php
$original = '001110100000010001000101011100001011010010011001101000001010011011000100001110011000011001000101011011110000101110100000110100010111010001000100101001110000011010001001';

the problem is urs only does the firt but

and theres like 4 bits

 

 

i tried doing all 4 bits but it fails

<?php

function convert(&$binary) {
$conbinary = substr($binary,$farin,-1);


if $conbinary = 1;
	if $farin = 4 then $conbinary2=1
	if $farin = 3 then $conbinary2=2
	if $farin = 2 then $conbinary2=4
	if $farin = 1 then $conbinary2=8
endif

if $farin=1
$convertedbinary = $conbinary+$conbinary+$conbinary+$conbinary
$farin=5
endif

$farin = $farin-1;

}

function zwalk(&$element) {

	$element = strrev($element);

}

function cutitup(&$cutup) {
	if $binaryno=3
	$cutup = 2

	endif

	if $binaryno=2
	$cutup = 4
	endif

	if $binaryno=4
	$cutup = 8

	$wayin = $wayin + $cutup

	substr($original,$wayin,$cutup);

';

$binary=1


//repeat untill the end, how do i do?

array_walk($original,'trimit');
array_walk2($original,'cutitup');
array_walk3($original,'zwalk');




$newamount = $neworiginal1.$neworiginal2.$neworiginal3.$neworiginal4.$neworiginal5.$neworiginal6.$neworiginal7.$neworiginal8.$neworiginal9.$neworiginal10.$neworiginal11;

if u look here

http://www.outscape.org/test/convert.php

it does it all sole the converting well not exactly it all

its too much code and too long winded

 

its just doing part of it like the first half of the binary

 

<?php
