Convert timestamp to date

The code is as follows:
Date ("Y-m-d H: I", $ unixtime)

2. obtain the timestamp of today's in php.

To obtain the unix timestamp at zero point, you can use $ todaytime = strtotime ("today "),

Then use date ("Y-m-d H: I", $ todaytime) to convert to date.

3. in php, the timestamp is converted to a date and different content is displayed according to the time, such as just, minutes ago, hours ago, today, yesterday, etc.

/* Time conversion function */

The code is as follows:

Function transTime ($ ustime ){ $ Ytime = date ("Y-m-d H: I", $ ustime ); $ Rtime = date ("n month j day H: I", $ ustime ); $ Htime = date ("H: I", $ ustime ); $ Time = time ()-$ ustime; $ Todaytime = strtotime ("today "); $ Time1 = time ()-$ todaytime; If ($ time <60 ){ $ Str = 'gang '; } Else if ($ time <60*60 ){ $ Min = floor ($ time/60 ); $ Str = $ min. 'minute ago '; } Else if ($ time <$ time1 ){ $ Str = 'Today '. $ htime; } Else { $ Str = $ rtime; } Return $ str; }

In this function, you can add more comparisons to make the displayed date more specific. for example, you can add more specific dates before the second or the day before yesterday.
