PHP - Roman Numerals To Decimal Conversion Question

I just downloaded and installed IP2Location database and everything is smooth for IPv4 addresses. (If you want to get location from peoples IP the free version is he http://lite.ip2locat...ipcode-timezone) You convert the IPv4 address to an IP number and then do a database query. See he

$ip_split = split ("\.", "$ip");
$ip_num = $ip_split[3] + ($ip_split[2] * 256) + ($ip_split[1] * 256 * 256) + ($ip_split[0] * 256 * 256 * 256);

$result = mysql_query("SELECT * FROM ip2location_db11 WHERE '$ip_num' BETWEEN ip_from AND ip_to");

However I now need to do this for an IPv6 address but there is no documentation or anything I can find Googleing about how to do this for IPv6. Obviously the same method will not work as it has letters in the address as well as more numbers. There is obviously some difference to it. Anyone know what to do?   Thanks!

Hi, I'm trying to force 2 decimal places with the following function but it 's not working.  Any suggestions? 

Code: [Select]
function ShippingCost() {
$shippingCost = 4.00;
    number_format($shippingCost,2);
return $shippingCost;
}

Hi I need to convert hex or Decimal to Binary but can't find any function. Any one have one or ideas please.

I'm making a connection to Active Directory using ADODB connection. I can read almost everything from this but some outputs are in an Octet format.
For example objectSID is giving me only a ?.
Is there somebody that knows how to read or convert this?

I've found a converter function in ASP maybe someone can translate this to PHP?

Code: [Select]
TXT_ObjectGUID = HexStrToDecStr(OctetToHexStr(objRecordSet.fields("objectSID")))

Function OctetToHexStr(arrbytOctet)
' Function to convert OctetString (byte array) to Hex string.
Dim k
OctetToHexStr = ""
For k = 1 To Lenb(arrbytOctet)
OctetToHexStr = OctetToHexStr _
& Right("0" & Hex(Ascb(Midb(arrbytOctet, k, 1))), 2)
Next
End Function

Function HexStrToDecStr(strSid)
' Function to convert hex Sid to decimal (SDDL) Sid.
Dim arrbytSid, lngTemp, j

ReDim arrbytSid(Len(strSid)/2 - 1)
For j = 0 To UBound(arrbytSid)
arrbytSid(j) = CInt("&H" & Mid(strSid, 2*j + 1, 2))
Next

HexStrToDecStr = "S-" & arrbytSid(0) & "-" _
& arrbytSid(1) & "-" & arrbytSid(8)

lngTemp = arrbytSid(15)
lngTemp = lngTemp * 256 + arrbytSid(14)
lngTemp = lngTemp * 256 + arrbytSid(13)
lngTemp = lngTemp * 256 + arrbytSid(12)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(19)
lngTemp = lngTemp * 256 + arrbytSid(18)
lngTemp = lngTemp * 256 + arrbytSid(17)
lngTemp = lngTemp * 256 + arrbytSid(16)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(23)
lngTemp = lngTemp * 256 + arrbytSid(22)
lngTemp = lngTemp * 256 + arrbytSid(21)
lngTemp = lngTemp * 256 + arrbytSid(20)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(25)
lngTemp = lngTemp * 256 + arrbytSid(24)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

End Function

Hi there,

I have a database with table column called EXPAMOUNT

if EXPAMOUNT value was £5.50
it only displays £5.5. when i echo it. How do i get it to display 2 decimal places. So £5.50

My code at moment

echo “Total Expenses &nbsp &pound” . $row[‘SUM(EXPAMOUNT)’]. “
