Couple of functions that convert an IP address into its color code and not-color-code

<? 

/*this function converts $ipaddr into a color string*/ 
function IP2Color($ipaddr) { 

$pieces=explode(".",$ipaddr); 
$color=""; 

for($i=0;$i<3;$i++) { 
    if(($pieces[$i]>=0) && ($pieces[$i]<=255)) { 
        $color.=dechex($pieces[$i]); 
    } 
} 
$color=substr($color."000000",0,6); 
return("#".strtoupper($color)); 
} 


/*this function converts $ipaddr 
to anti color string*/ 

function IP2NotColor($ipaddr) { 

$pieces=explode(".",$ipaddr); 
$color=""; 

for($i=0;$i<3;$i++) { 
    if(($pieces[$i]>=0) && ($pieces[$i]<=255)) { 
        $color.=dechex((128+$pieces[$i]) % 255); 
    } 
} 
$color=substr($color."000000",0,6); 
return("#".strtoupper($color)); 
} 


Example: 

$IP=getenv("REMOTE_ADDR"); 
print "<table><tr>\n"; 
print "    <td bgcolor='".IP2Color($IP)."'><font face='Arial,Courier' 
color='".IP2NotColor($IP)."'>$IP</font></td>\n"; 
print "</tr></table>\n"; 
?>
