PHP format timestamp display friendly time implementation ideas and code, PHP ideas

All the time in the project was shown as 2014-10-20 10:22 and it looked stiff. In the microblogging, QQ space and other sites are usually displayed for a few seconds ago, a few minutes ago, a few hours ago, such as easy to read time, we call it a friendly time format. So how do you do it with PHP?

The general idea is as follows:

If it is cross-year and is greater than 3 days, it is displayed for a specific time

If it's Today's

If it's a minute, it's a few seconds ago.

If it's within an hour, it shows a few minutes ago.

If it is the same day and is greater than one hour, it will be displayed a few hours ago

If it was yesterday, what time did it show yesterday?

If it was the day before yesterday, what time did you see

If it is greater than three days (no cross-year), the number of months is displayed

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

The implementation code is as follows:

Format 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);//distance of days, this method more than 30 days is not necessarily accurate, but 30 days is accurate, because one months may be 30 days also may be 31 days $days= ($TODAYARR [0]-$dayArr [0]) *365+ (($todayArr [1]-$DAYARR [1]) *30) + ($TODAYARR [2]-$DAYARR [2]);//number of seconds in distance $secs= $now-$time; if ($ todayarr[0]-$DAYARR [0]>0 && $days >3) {//cross-year 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 $hour=date (' H ', $time); return "The day before yesterday" $hour. ' Point '; else{//three days ago return date (' m-month d ', $time);}}

Kneeling PHP time converted to timestamp code

There is a case of Chinese. You need to replace the Chinese characters with the regular one. Because that's not the standard format.

Can be handled with the following code.

$date = "November 01, 2009 15:12"; Must be a standard double-digit date
$date = Ereg_replace ("[^0-9]", "", $date); Filter non-digital
$time = Strtotime ($date); The variable $time is the time stamp.

But. If you are using the current time. Just write it a bit faster like this.
$time = time ();

The PHP date function can format the timestamp as 2012-5-3

Date (' Y-n-j ', Time ()); The time () function generates a timestamp of the current time, which can be replaced by your own timestamp
