PHP erhält Zeitunterschied

PHP ermittelt die Zeitdifferenz. Dies ist eine Funktion, die wir häufig während des Entwicklungsprozesses verwenden. Wenn wir beispielsweise die Daten eines bestimmten Zeitraums überprüfen möchten, verwenden wir diese Funktion.

Beispiel eins:

/**
 * 功能：获取时间差
 * @param int $time
 * @return string 时间差值
 */
function tranTime($time) {
    $rtime = date("m-d H:i",$time);
    $htime = date("H:i",$time);
 
    $time = time() - $time;
 
    if ($time < 60) {
        $str = &#39;刚刚&#39;;
    }
    elseif ($time < 60 * 60) {
        $min = floor($time/60);
        $str = $min.&#39;分钟前&#39;;
    }
    elseif ($time < 60 * 60 * 24) {
        $h = floor($time/(60*60));
        $str = $h.&#39;小时前 &#39;.$htime;
    }
    elseif ($time < 60 * 60 * 24 * 3) {
        $d = floor($time/(60*60*24));
        if($d==1)
           $str = &#39;昨天 &#39;.$rtime;
        else
           $str = &#39;前天 &#39;.$rtime;
    }
    else {
        $str = $rtime;
    }
    return $str;
}

Beispiel zwei:

function time_tran($the_time){
   $now_time = date("Y-m-d H:i:s",time()+8*60*60);
   $now_time = strtotime($now_time);
   $show_time = strtotime($the_time);
   $dur = $now_time - $show_time;
   if($dur < 0){
    return $the_time;
   }else{
    if($dur < 60){
     return $dur.&#39;秒前&#39;;
    }else{
     if($dur < 3600){
      return floor($dur/60).&#39;分钟前&#39;;
     }else{
      if($dur < 86400){
       return floor($dur/3600).&#39;小时前&#39;;
      }else{
       if($dur < 259200){//3天内
        return floor($dur/86400).&#39;天前&#39;;
       }else{
        return $the_time;
       }
      }
 }

Beispiel drei:

function format_date($time){
    $t=time()-$time;
    $f=array(
        '31536000'=>'年',
        '2592000'=>'个月',
        '604800'=>'星期',
        '86400'=>'天',
        '3600'=>'小时',
        '60'=>'分钟',
        '1'=>'秒'
    );
    foreach ($f as $k=>$v)    {
        if (0 !=$c=floor($t/(int)$k)) {
            return $c.$v.'前';
        }
    }
}

Beispiel vier:

function formatTime($date) {
$str = '';
$timer = strtotime($date);
$diff = $_SERVER['REQUEST_TIME'] - $timer;
$day = floor($diff / 86400);
$free = $diff % 86400;
if($day > 0) {
return $day."天前";
}else{
if($free>0){
$hour = floor($free / 3600);
$free = $free % 3600;
if($hour>0){
return $hour."小时前";
}else{
if($free>0){
$min = floor($free / 60);
$free = $free % 60;
if($min>0){
return $min."分钟前";
}else{
if($free>0){
return $free."秒前";
}else{
return '刚刚';
}
}
}else{
return '刚刚';
}
}
}else{
return '刚刚';
}
}
}

Beispiel fünf:

function time_tran($the_time){
$now_time = date("Y-m-d H:i:s",time()+8*60*60); 
$now_time = strtotime($now_time);
$show_time = strtotime($the_time);
$dur = $now_time - $show_time;
if($dur < 0){
return $the_time; 
}else{
if($dur < 60){
    return $dur.&#39;秒前&#39;; 
}else{
    if($dur < 3600){
   return floor($dur/60).&#39;分钟前&#39;; 
    }else{
   if($dur < 86400){
   return floor($dur/3600).&#39;小时前&#39;; 
   }else{
   if($dur < 259200){//3天内
       return floor($dur/86400).&#39;天前&#39;;
   }else{
       return $the_time; 
   }
   }
    }
}
}
}
