PHP Code:


			
stock ConvertDate(String:date1[], String:date2[])
{
    ReplaceString(date1, strlen(date1)+1, "-", ""); // replace 2011-12-22 to 20111222
    ReplaceString(date2, strlen(date2)+1, "-", "");

    decl String:strYear[2][5], String:strMonth[2][3];
    strcopy(strYear[0], sizeof(strYear[]), date1); // strYear[0] = "2011"
    strcopy(strYear[1], sizeof(strYear[]), date2); 

    ReplaceString(date1, strlen(date1)+1, strYear[0], ""); // date1 = "1222"
    ReplaceString(date2, strlen(date2)+1, strYear[1], ""); 

    strcopy(strMonth[0], sizeof(strMonth[]), date1); // strMonth[0] = "12"
    strcopy(strMonth[1], sizeof(strMonth[]), date2); 

    ReplaceString(date1, strlen(date1)+1, strMonth[0], ""); // date1 = "22" 
    ReplaceString(date2, strlen(date2)+1, strMonth[1], "");

    if (!strlen(date1)) strcopy(date1, sizeof(strMonth[]), strMonth[0]); // if month == day, exampel "20110808"
    if (!strlen(date2)) strcopy(date2, sizeof(strMonth[]), strMonth[1]);

    // (year1 - year2)*365 + (month1 - month2)*30 + (day1 - day2)  
    return (StringToInt(strYear[0]) - StringToInt(strYear[1])) * 365 + (StringToInt(strMonth[0]) - StringToInt(strMonth[1])) * 30 + (StringToInt(date1) - StringToInt(date2));
}

OK. example:

PHP Code:


			
public OnPluginStart()

{

    decl String:date1[]="2011-12-24";

    decl String:date2[]="2011-12-22";

    

    LogMessage("ConverDate: %s to %s is %d", date1, date2, ConvertDate(date1, date2));

}



stock ConvertDate(String:date1[], String:date2[])

{

    ReplaceString(date1, strlen(date1)+1, "-", ""); // replace 2011-12-22 to 20111222

    ReplaceString(date2, strlen(date2)+1, "-", "");



    decl String:strYear[2][5], String:strMonth[2][3];

    strcopy(strYear[0], sizeof(strYear[]), date1); // strYear[0] = "2011"

    strcopy(strYear[1], sizeof(strYear[]), date2);



    ReplaceString(date1, strlen(date1)+1, strYear[0], ""); // date1 = "1222"

    ReplaceString(date2, strlen(date2)+1, strYear[1], "");



    strcopy(strMonth[0], sizeof(strMonth[]), date1); // strMonth[0] = "12"

    strcopy(strMonth[1], sizeof(strMonth[]), date2);



    ReplaceString(date1, strlen(date1)+1, strMonth[0], ""); // date1 = "22" 

    ReplaceString(date2, strlen(date2)+1, strMonth[1], "");



    if (!strlen(date1)) strcopy(date1, sizeof(strMonth[]), strMonth[0]); // if month == day, exampel "20110808"

    if (!strlen(date2)) strcopy(date2, sizeof(strMonth[]), strMonth[1]);



    // (year1 - year2)*365 + (month1 - month2)*30 + (day1 - day2) 

    return (StringToInt(strYear[0]) - StringToInt(strYear[1])) * 365 + (StringToInt(strMonth[0]) - StringToInt(strMonth[1])) * 30 + (StringToInt(date1) - StringToInt(date2));

}

result:

PHP Code:


			
L 12/23/2011 - 09:43:13: [new.smx] ConverDate: 24 to 22 is 2
