md5, POST/COOKIE/GET

[Anon]

hey,
im trying to a validation check of a url, hashing its variable names and values along with an unknown string using md5

however, while looping through the associative array produced by post/cookie/get methods, i some how do not obtain the same hash value

could somebody give me a more direct way to do this or tell me what im doing wrong?

it appears that the second hash value is made with out the unknown string attached
while i defined it and appended it to the original variable names and values

where's the code?

for url

$url = http://www.whatever.com/index.php?variable1=value1&variable2=value2

define( 'unknownstring', 'fdasfdsafdsa' );

$secret = md5( "$variable1.'value1'.$variable2.'variable2'.$unknownstring" );

append this to the url

$new = $url.$secret;

then go to script page that processes for verification

$something = $HTTP_GET_VARS;

do foreach, taking the variable names and values out of the associative array
appending them together under variable name $query until loop is done

then do
$check = md5( "$query.$unknownstring" )
under a new variable name $query

check against each other

if( $new != $check )
print "you are bad, go away";

unfortunately, i have not been able to get the hash to match the other.

ive printed all the different combinations for the second hash that i could think of,
without the unknown string, with the unknown string, using $unknownstring = 'fdasfdsafdsa'; instead of define.
appending the unkownstring without the $ sign

i can never get the same hash value, though
