PHP获取时间差

PHP获取时间差,我们在开发过程中，这是一个经常使用到的函数，比如说我们想查某个时间段的数据，那就要用到这个函数了。

实例一：

/** * 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) {        $str = '刚刚';    }    elseif ($time < 60 * 60) {        $min = floor($time/60);        $str = $min.'分钟前';    }    elseif ($time < 60 * 60 * 24) {        $h = floor($time/(60*60));        $str = $h.'小时前 '.$htime;    }    elseif ($time < 60 * 60 * 24 * 3) {        $d = floor($time/(60*60*24));        if($d==1)           $str = '昨天 '.$rtime;        else           $str = '前天 '.$rtime;    }    else {        $str = $rtime;    }    return $str;}

实例二：

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 $dur.'秒前';    }else{     if($dur < 3600){      return floor($dur/60).'分钟前';     }else{      if($dur < 86400){       return floor($dur/3600).'小时前';      }else{       if($dur < 259200){//3天内        return floor($dur/86400).'天前';       }else{        return $the_time;       }      } }

实例三：

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';        }    }}

实例四：

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';}}}

实例五：

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 $dur.'秒前'; }else{    if($dur < 3600){   return floor($dur/60).'分钟前';     }else{   if($dur < 86400){   return floor($dur/3600).'小时前';    }else{   if($dur < 259200){//3天内       return floor($dur/86400).'天前';   }else{       return $the_time;    }   }    }}}}

实例六：
