The date diff   function returns the difference between two DateTime objects   If the first date is before the second date a positive number of days will be returned  otherwise a negative number of days    lt  php  date1 date create  2013-03-15     date2 date create  2013-12-12     diff date diff  date1  date2   echo  diff- gt format   R a days      gt    output will be    272 days     changing   date1    2014-03-15     lt  php      date1 date create  2014-03-15         date2 date create  2013-12-12         diff date diff  date1  date2       echo  diff- gt format   R a days          gt    Output will be   -93 days

If both dates are in the same format then use a comparison operator    date1    2018-05-05     date2    2019-08-19       comparison operator to    if   date1  gt   date2        echo   date1 is latest than  date2          else      echo   date1 is older than  date2            Output  2018-05-05 is older than 2019-08-19

You will have to make sure that your dates are valid date objects   Try this    date1 date  d m y     tempArr explode       31 12 11     date2   date  d m y   mktime 0  0  0   tempArr 1    tempArr 0    tempArr 2       You can then perform the strtotime   method to get the difference

I know this is late  but for future reference  put the date format into a recognised format by using str replace then your function will work   replace the underscore with a dash     change the format to dashes instead of underscores  then get the timestamp  date1   strtotime str replace       -   date1     date2   strtotime str replace       -   date2       compare the dates if  date1  lt   date2        convert the date back to underscore format if needed when printing it out     echo  1 is small    date1     date  d m y   date1    else     echo  2 is small    date2     date  d m y   date2
