Several steps for obtaining time in php (collection)

Several methods for getting time in php (collection) 1. jddayofweek (cal_to_jd (CAL_GREGORIAN, date ('M'), date ('D '), date ('Y'); this function returns the day of the Week 2, array ('mon' = & gt; 'Monday ',......); then you can directly subscripts to query 3. several methods for getting time in the root php (collection)
1. jddayofweek (cal_to_jd (CAL_GREGORIAN, date ('M'), date ('D'), date ('Y'); this function returns the number of days in the week
2. array ('mon '=> 'Monday',...); then directly subscript query
3. get the week-based custom functions

 '; Echo' today is: '. getWeekName (time (), 'week'); echo'
'; Echo '2017-12-12 is:'. getWeekName (strtotime ('2017-12-12 '), 'week');?>

4. get the user-defined functions for the effects such as a few hours ago posted in a similar article

 'Year', 'month' => 'month', 'week' => 'week', 'day' => 'day ', 'hour '=> 'hour', 'mine' => 'Minute ', 'second' => 'second'); foreach ($ unitArr as $ cn => $ u) {if ($ u> 0) {$ elapse = $ u. $ cn; break ;}}return $ elapse ;}$ past = 2052345678; // release date $ now = time (); // Current date $ diff = $ now-$ past; // difference echo 'published on '. time2Units ($ diff ). 'pre';?>

In other words, I think it is better:

Function time_tran ($ the_time) {$ now_time = date ("Y-m-d H: I: s", time () + 8*60*60 ); $ now_time = strtotime ($ now_time); $ show_time = strtotime ($ the_time); $ dur = $ now_time-$ show_time; if ($ dur <0) {return $ the_time ;} else {if ($ dur <60) {return $ dur. 'seconds ago ';} else {if ($ dur <3600) {return floor ($ dur/60 ). 'minute ago ';} else {if ($ dur <86400) {return floor ($ dur/3600 ). 'hour before ';} else {if ($ dur <259200) {// return floor ($ dur/86400) within 3 days ). 'Day' ;}else {return $ the_time ;}}}}}}

5. calculate the time difference based on the difference

Function getTime ($ val) {if ($ val> 0) {$ nTime ['nday'] = (int) ($ val/(3600*24 )); $ nTime ['nhour'] = (int) ($ val % (3600*24)/3600); $ nTime ['nmin'] = (int) ($ val % (3600*24) % 3600/60); $ nTime ['nss'] = (int) ($ val % (3600*24) % 3600% 60 );} return $ nTime;} function getStrTime ($ val) {$ aTime = getTime ($ val); $ dtoc = array ('nday' => 'day ', 'nhour' => 'hour ', 'nmin' => 'Minute', 'nss' => 'second '); if ($ aTime) {foreach ($ aTime as $ k => $ v) {if ($ v) {$ cTime. = $ v. $ dtoc [$ k] ;}}else {$ cTime = 'stopped;} return $ cTime ;}
