Would this code work ?

PHP код:

stock IsIP(ip[], size=sizeof(ip))
{
    new dots = 0, nums = 0, other = 0;
    for(i = 0; i < size, i++)
    {
        switch(ip[i])
        {
            case '.':
            {
                dots++;
            }
            case '0'..'9':
            {
                 nums++;
            }
            default:
            {
                other++;
            }
        }
    }
    if(dots < 3 || nums > 12 || other != 0) return 0;
    else return 1;
}

You could try it, although what would be the purpose of you using this?

Work for what precisely?

It would detect something like 999.999.999.999, which is not a valid IP. The following is a bit more precise:

PHP код:

bool:IsIP(string[])
{
    new parts[4];
    
    if(sscanf(string, "p<.>a<i>[4]", parts))
        return false;
        
    for(new i; i < sizeof(parts); i++)
    {
        if(!(0 <= part[i] <= 255))
            return false;
    }
    
    return true;
} 


Although a regular expression is better still since it can locate them within other text.
