I may be just over thinking this but I'm stuck trying to figure out a
solution that has to deal with comparing a series of dynamic strings to a
known string. The strings will be 8 characters long and each character
will be either a zero or a 1. What I need to do is to compare the dynamic
strings with the known and if each of the 1 characters in the dynamic
string aligns with the 1 characters in the known string it will throw a
flag. The dynamic string does NOT need to contain all of the 1 characters
that the known string does, just that the ones that it contains align.
Examples:
Known:
10100010
Dynamic:
00100000 Throws flag because both strings contain a 1 in position 3
01100000 Doesn't throw flag because there is a 1 in position 2
10100000 Throws a flag because the 1s in position 1 and 3 align
10110000 Doesn't throw a flag because of the 1 in position 4
I was able to create a function that matches the entire string but I lost
it when trying to deal with partial matches. Does anyone have a potential
solution for such a beast? I appreciate any input you might be able to
offer...
Thanks,
Ron

Hi Ron,
Also in PHP a string is actually an array of characters. Maybe you can pick
out each character and compared it to the character in the same position of
the known string!
Example:
// Get the first character of a string
$str = 'This is a test.';
$first = $str{0};
// Get the third character of a string
$third = $str{2};
Cheers, RICO

For an exhaustiv brute force partial match, between string 1 and
string 2. Take the first string and break it up in segment of
lenght 1,2,3,...,n-1, where n is the lenght of string 1.
Then for each of these segment do a "string-find-in-string"
in the second string - if you get a hit, then you have a
partial match.

will be either a zero or a 1. What I need to do is to compare the

strings with the known and if each of the 1 characters in the dynamic
string aligns with the 1 characters in the known string it will throw a
flag. The dynamic string does NOT need to contain all of the 1
characters
that the known string does, just that the ones that it contains align.

Known:
10100010
Dynamic:
00100000 Throws flag because both strings contain a 1 in position 3

Umm..
$static=bindec('10100000');
$dynamic=bindec('10110000');
# Can't think right now, but it seems like
# you can just do this instead: $dynamic & ~$static
if(($static|$dynamic)& ~$static)
{
# Don't throw flag
}
else
{
# Throw flag
}
It throws a flag, if all 1's in the dynamic string has a match in the static
one, but not if the static one has a 1 that the other doesn't have..
Correct?

You use the meta-tag-style in PHP as well, or a javascript..

Hi!
People who do not check anything that comes in by internet should see a
doctor concerning suicidal tendences. Over here - every day I get at least
one virus (probably 2-3). But ... who cares ... Norton, F-Secure and co.
should care - but I ... got better things to do
Regards
Daniel
