php timestamp date Convert

1.php中时间转换函数

strtotime(“today”)

date("Y-m-d H:i",$unixtime)

2.php中获得今天零点的时间戳

要获得零点的unix时间戳,可以使用$todaytime=strtotime(“today”),

然后再使用date("Y-m-d H:i",$todaytime)转换为日期。

3.php中时间戳转换为日期,并按照时间显示不同的内容,如刚刚,分钟前,小时前,今天,昨天等

/*时间转换函数*/

function transTime($ustime) {           

  $ytime = date("Y-m-d H:i",$ustime);             

  $rtime = date("n月j日 H:i",$ustime);           

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

  $time = time() - $ustime;           

  $todaytime = strtotime("today");           

  $time1 = time() - $todaytime;                           

  if($time

    $str = '刚刚';           

  }else if($time

    $min = floor($time/60);                   

    $str = $min.'分钟前';           

  }else if($time

    $str = '今天 '.$htime;           

  }else{                   

    $str = $rtime;           

  }             

  return $str;

}

在这个函数中你可以添加更多的比较使显示的日期更加具体,比如添加 秒钟前,前天等更具体的日期。

4.php日期中补0与不补0

echo date('Y-m-d'); 显示2012-08-08

echo date('Y-n-j'); 显示2012-8-8
