2. Conversion between time stamp and time string

Timestamp function strtotime ()

    Get a timestamp of 0 points today to get a Unix timestamp of 0 points, you can use

$todaytime =strtotime ("Today"),

and then use

Date ("Y-m-d h:i", $todaytime) is converted to a day.

If the date is to be converted into a timestamp, it will be used Strtotime ()

$oldtime = ' 2010-11-10 22:19:21 ';

$catime = Strtotime ($oldtime);

3.php timestamps are converted to dates and display different content by time, such as just, minutes ago, hours ago, today, yesterday, etc.

function Transtime ($ustime) {

$ytime = Date ("y-m-d h:i", $ustime);

$rtime = Date ("M-D-Day h:i", $ustime);

$htime = Date ("H:i", $ustime);

$time = Time ()-$ustime;

$todaytime = Strtotime ("Today");

$time 1 = time ()-$todaytime;

if ($time < 60) {

$str = ' just ';

}else if ($time < 60 * 60) {

$min = Floor ($time/60);

$str = $min. ' Minutes ago ';

}else if ($time < $time 1) {

$str = ' Today '. $htime;

}else{

$str = $rtime;

}

return $str;
