Php timestamp format display friendly time function sharing

In some Weibo systems, the time is usually displayed before the current time, such as: just five seconds ago, five hours ago, five days ago .. this display is very friendly, so how can we use php to implement it? this is the content discussed in this article, for more information, see <g id = "1"> Project </g>. Websites such as Weibo and QQ space are usually displayed in a friendly time format that is a few seconds ago, a few minutes ago, or a few hours ago. So how can we implement it using php?

The general idea is as follows:

If it is a new year and more than 3 days, it is displayed as a specific time

If it is today's

If it is within one minute, it is displayed a few seconds ago.

If it is within one hour, it will be displayed several minutes ago

If it is the same day and more than one hour, it is displayed as a few hours ago

If it was yesterday, it is displayed as the time of yesterday

If it is the day before yesterday, it is displayed as the day before yesterday

If it is more than three days (not cross-year), it is displayed as the number of months

Based on the above ideas, it is not difficult to write the implementation code:

The implementation code is as follows:

The code is as follows:

// Format the friendly display time
Function formatTime ($ time ){
$ Now = time ();
$ Day = date ('Y-m-D', $ time );
$ Today = date ('Y-m-D ');

$ DayArr = explode ('-', $ day );
$ TodayArr = explode ('-', $ today );

// The number of days in the distance. this method is not necessarily accurate if it is more than 30 days, but it is accurate within 30 days, because a month may be 30 days or 31 days.
$ Days = ($ todayArr [0]-$ dayArr [0]) * 365 + ($ todayArr [1]-$ dayArr [1]) * 30) + ($ todayArr [2]-$ dayArr [2]);
// Number of seconds
$ Secs = $ now-$ time;

If ($ todayArr [0]-$ dayArr [0]> 0 & $ days> 3) {// cross-year period and more than 3 days
Return date ('Y-m-D', $ time );
} Else {

If ($ days <1) {// today
If ($ secs <60) return $ secs. 'seconds ago ';
Elseif ($ secs <3600) return floor ($ secs/60). "minutes ago ";
Else return floor ($ secs/3600). "hours ago ";
} Else if ($ days <2) {// yesterday
$ Hour = date ('H', $ time );
Return "yesterday". $ hour. 'point ';
} Elseif ($ days <3) {// The day before yesterday
$ Hour = date ('H', $ time );
Return "the day before yesterday". $ hour. 'point ';
} Else {// three days ago
Return date ('M-d ', $ time );
}
}
}
