How to obtain age from date of birth? - Jose_grana - 11.08.2018

In my gm I save the date in a string with the format Day / Month / Year.

Example:

02/21/1990

How could I get the age by getting the current server date?

Example.

21/02/1990.- 12/08/2018 = 28 years.

PHP код:
numdays(year, month) {
    switch (month) {
        case 4, 6, 9, 11: {
            return 30;
          }
        case 2: {
            if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)) {
                return 29;
            }
            return 28;
          }
    }
    
    return 31;
}
getage(birth_year, birth_month, birth_day) {
    new current_year, current_month, current_day;
    getdate(current_year, current_month, current_day);
    new sum;
    new cumulative_days[12];
    for (new i = 0; i < 12; ++i){
        sum += numdays(current_year, i);
        cumulative_days[i] = sum;
    }
    
    new age = (current_year - birth_year - 1);
    
    new days_this_year = (current_day + cumulative_days[current_month - 1]);
    new days_birth_year = (cumulative_days[11] - (birth_day + cumulative_days[birth_month - 1]));
    
    new total_days = (days_this_year + days_birth_year);
    
    age += total_days/365;
       return age;
}
// how to use
printf("Age: %i", getage(1995, 6, 30));

Why not

pawn Код:
new Age = current_year - birth_year;
? xd

cause it will be inaccurate once it comes to specific days (everyone from 1998 would be the same age in 201.

Re: How to obtain age from date of birth? - CaptainBoi - 12.08.2018

you can do it by taking the birth year and taking todays year
and make a format in which its going to take subtracted
then send client message
this is your age

Your code works perfect but only when defining the day, month and year.

My code:

pawn Код:
enum pInfo
{
    pBirthDate[24]
};
new PlayerInfo[MAX_PLAYERS][pInfo];
//Load variable

pawn Код:
cache_get_value_name(0, "Birthdate", PlayerInfo[extraid][pBirthDate],24);
//To modify the variable

pawn Код:
format(PlayerInfo[playerid][pBirthDate], 24, inputtext);
How can I use your function like this?

Thanks for you time!.

You'll have to split your string.
If your birthdate has this type of format: "21/02/1990"

You can do something like this:
PHP код:
test_function() {
    new string[] = "21/02/1990";

    new year, month, day;
    new pos, tmp[5];

    strmid(tmp, string, 0, (pos = strfind(string, "/", true, 0)));
    day = strval(tmp);
    
    strmid(tmp, string, pos + 1, (pos = strfind(string, "/", true, pos + 1)));
    month = strval(tmp);
    
    strmid(tmp, string, pos + 1, strlen(string));
    year = strval(tmp);

    printf("%i/%i/%i", day, month, year);
}
