<? Php/** + ------------------------------------------------------------ * function: calculate the difference between the two dates: year, month, and day + period * @ param date $ date1 start date * @ param date $ date2 end date + period * @ return array + period */function DiffDate ($ date1, $ date2) {if (strtotime ($ date1)> s Trtotime ($ date2) {$ ymd = $ date2; $ date2 = $ date1; $ date1 = $ ymd;} list ($ y1, $ m1, $ d1) = explode ('-', $ date1); list ($ y2, $ m2, $ d2) = explode ('-', $ date2 ); $ y = $ m = $ d =$ _ m = 0; $ math = ($ y2-$ y1) * 12 + $ m2-$ m1; $ y = round ($ math/12); $ m = intval ($ math % 12); $ d = (mktime (0, 0, 0, $ m2, $ d2, $ y2)-mktime (0, 0, 0, $ m2, $ d1, $ y2)/86400; if ($ d <0) {$ m-= 1; $ d + = date ('J', mktime (0, 0, 0, $ m2, 0, $ y2);} $ m <0 & $ y-= 1; return array ($ y, $ m, $ d) ;}?>
