PHP subnet calculator

The original code was written by Raymond Ferguson , so all credits goes to him .
I made a few modifications on the code , now it is also compatible with  PHP >= 5.3 .

Note :
Although this script isn't perfect , it can help out to quickly calculate subnet-shemas ( number of hosts , broadcast domain , network id ) .
Bugs :  Even if  you try to resolve a Class C with an CIDR  lower than 24  , let say 18 , it will calculate output .
