Convert timestamp to date

Time stamp conversion function:

date("Y-m-d H:i:s",time()),"Y-m-d H:i: s" is the converted date format, time() is the timestamp to obtain the current time. If it is date("Y-m-d H:i:s", time()), the hours, minutes and seconds will be displayed together; if it is

date("Y-m-d ", time( )), only the year, month and day are displayed. For example:

date("Y-m-d H:i:s",time())

after conversion is:

2010-07-18 18:42:48

date("Y-m-d",time())

After conversion:

2010-07-18 Date conversion It is a timestamp.

class SaonekController extends Controller { 
 public function index
Action
(){ 
/*

It goes without saying that the timestamp is converted into a date

But if the date is to be converted into a timestamp, it must be used

strtotime() 
*/ 
         $time = time();//

Timestamp

   $nowtime = date('Y-m-d H:i:s',$time);//

Generate formatted date

  $oldtime = '2010-11-10 22:19:21'; 
         $catime = strtotime($oldtime);//

Convert date to timestamp

   $nowtimes = date('Y-m-d H:i:s',$catime);//

Time stamp is converted back to date

   echo  $nowtimes; 
 } 
} 
?>

$rtime = date("n月j日 H:i",$ustime); 
             
$htime = date("H:i",$ustime);  
           
$time = time() - $ustime;   
          
$todaytime = strtotime("today"); 
            
$time1 = time() - $todaytime;  
                           
if($time < 60){    
                  
$str = &#39;刚刚&#39;;   
           
}else if($time < 60 * 60){  
                             
$min = floor($time/60);                      
$str = $min.&#39;分钟前&#39;;
