Hello everybody, so iam going to show you how to calculate your Age with full detailes (Y/M/H/m/s/ms/ns/ms) in PHP by Date of Birth.

If you Wanna Calculate your real Age in numeric format:
You Have to subtract date('year') from date('Y') and insert on the last date function's timestamp argument strtotime('Year-Month-Day')

PHP Code: (Select All)

To Be: date("Y") - date("Y", strtotime('Year-Month-Day'))
For Example: date("Y") - date("Y", strtotime('2002-09-16'))) 


Output:

Code: (Select All)

16

If you Wanna Calculate your real age with full details (Y/M/H/m/s/ms/ns/ms):
1- We initializate the $datebirth var with the DateTime Class and set the timestamp argument of the DateTime Class to your Date of Birth with the following Syntax Year-Month-Day

PHP Code: (Select All)

To Be: $datebirth = new DateTime('Year-Month-Day');
For Example: $datebirth = new DateTime('2002-09-16'); 


2- We initializate the $today var with the DateTime Class without setting any arguments to get Today's Timestamp

PHP Code: (Select All)

To Be: $today = new DateTime; 


3- We do the algorithm to calculate the requested Person's Age with DateTime::diff and then to get the result we must use DateInterval::Format

PHP Code: (Select All)

For Example: echo $today->diff($dabi)->format('%y Years, %m Months, %d Days, %h Hours, %I Minutes, %s Seconds, ' . ($today->diff($dabi)->format('%s')*1000) . ' Milliseconds, ' . ($today->diff($dabi)->format('%s')*1000*1000000) . ' Nanoseconds, ' . ($today->diff($dabi)->format('%s')*1000*1000000*1000) . ' Microseconds'); 


Let's Discuss somethings in our small algorithm...

• We multiply the seconds in one thousand to get the Milliseconds.(Second = 1000 Milliseconds)
  
• We multiply the milliseconds in one thousand ms and the result get multiplied in one million ms to get the Nanosecond.(Nanosecond = 1000000 Millisecond)
  
• We multiply the Microseconds in one thousand ms and the result get multiplied in one million ms and the second result get multiplied in one thousand, to get the Microsecond.(Microsecond = 1000 Nanosecond)
  

Output:

Code: (Select All)

15 Years, 8 Months, 3 Days, 19 Hours, 25 Minutes, 45 Seconds, 45000 Milliseconds, 45000000000 Nanoseconds, 45000000000000 Microseconds

Nice one zorono..
i remember old times , when i used Pascal :p

Simply use android app " age calculator.apk " for exact years, months, days, hours, etc ... also calculate difference between two ages

Wow awesome! Keep it up bro
Any tutorials for SAMP UCP & ACP?

i don't need this script or any app to calculate my age because i became 20th this 9th May.

Can it be accurate to seconds without we giving the time in second? I do not think it can be unless we input time in seconds, between a simple code.

you might do it by using the following:

PHP Code: (Select All)

echo $today->diff($dabi)->format('%y Years, %m Months, %d Days, %h Hours, %I Minutes, '  . ($today->diff($dabi)->format('%I')*60) . 'Seconds, ' . ($today->diff($dabi)->format('%s')*1000) . ' Milliseconds, ' . ($today->diff($dabi)->format('%s')*1000*1000000) . ' Nanoseconds, ' . ($today->diff($dabi)->format('%s')*1000*1000000*1000) . ' Microseconds'); 


you can get the seconds by multiplying the Minutes in 60.

Ohhhh... it's mean the sweet teen is gone. now you are going to mature sector of age.
