Convert php script to use BCMath instead of GMP

[Bouncer222]

Hey all, I need this script to use BCMath instead of GMP. My webserver is on a shared hosting and they don't support GMP. So the part of this code where there is GMP, I need to have it us BCMath instead, therefore it needs to be edited.

Please PM me with the price and how long this would take.
Thanks.


<?
define("ACC_NAME", "bouncer222");

define("GROUP_ID", "103582791430981168"); // open steam group page and see "Enter chat room" link, which contains ID
define("MY_STEAM_ID", "STEAM_0:0:35005283"); // steam ID which can invite to join group

$invite_steam_id = $_GET['i'];

$ids = file('invited_ids.txt');
foreach($ids as $id) {
$id = trim($id);
if ( $id == $invite_steam_id )
die($id .": Already invited!\n");
}

function GetFriendID( $steam_id ) {
if ( !$steam_id )
return 0;
$auth = explode(':', $steam_id);
if ( !$auth[2] )
return 0;
$fid = gmp_init($auth[2]);
$fid = gmp_mul($fid, "2");
$fid = gmp_add($fid, "76561197960265728");
$fid = gmp_add($fid, $auth[1]);
return gmp_strval($fid);
}

You can also use this php snippet to replace the GMP one maybe (I have almost zero knowledge in php, I found this on a site, it's suposed to also do the same function that the GMP does.


__int64 GetFriendID( const char *pszAuthID )
{
if(!pszAuthID)
return 0;

int iServer = 0;
int iAuthID = 0;

char szAuthID[64];
strcpy_s(szAuthID, 63, pszAuthID);

char *szTmp = strtok(szAuthID, ":");
while(szTmp = strtok(NULL, ":"))
{
char *szTmp2 = strtok(NULL, ":");
if(szTmp2)
{
iServer = atoi(szTmp);
iAuthID = atoi(szTmp2);
}
}

if(iAuthID == 0)
return 0;

__int64 i64friendID = (__int64)iAuthID * 2;

//Friend ID's with even numbers are the 0 auth server.
//Friend ID's with odd numbers are the 1 auth server.
i64friendID += 76561197960265728 + iServer;

return i64friendID;
}
