<?php

### [ip proxied] ###
$posn=0;
do {
$posn++; # increment $POSN.
if ($a{$posn} == ',') { # if inside the $A string, at the $POSN character
-- there is a "," character
break; # .. exit the do/while loop.
}
} while ($posn < strlen($a)); # do until the end of the $A string has been reached.
$login_ip = substr($a,0,$posn); # $LOGIN_IP = from 0 to $POSN characters of $A string
# $A = "nigger", [0=>4] === {nigg}
} else {
### [ip standard] ###
$login_ip = $b;

$login_host = gethostbyaddr($login_ip);
