Thank you, I hadn't noticed this category at first. I've figured out how to do it, in case someone need this:
PHP Code:
char serverip[32];
int ip = g_pCvar->FindVar("hostip")->GetInt();
int port = g_pCvar->FindVar("hostport")->GetInt();
int iips[4];
iips[0] = (ip >> 24) & 0x000000FF;
iips[1] = (ip >> 16) & 0x000000FF;
iips[2] = (ip >> 8) & 0x000000FF;
iips[3] = ip & 0x000000FF;
snprintf(serverip, sizeof(serverip), "%d.%d.%d.%d:%d", iips[0], iips[1], iips[2], iips[3], port);
