在php中时间日期的表达方式有很多种,最常用的是就是时间戳与普通的日期格式,下面我来介绍时间戳与日期之间的转换。
1.php中时间转换函数
strtotime
strtotime() 函数将任何英文文本的日期时间描述解析为 Unix 时间戳。
语法
strtotime(time,now)
例
代码如下 | 复制代码 |
strtotime(“today”) |
date
PHP Date() 函数可把时间戳格式化为可读性更好的日期和时间。
语法
date(format,timestamp)
例
代码如下 | 复制代码 |
echo date("Y/m/d"); |
把时间戳转换日期
代码如下 | 复制代码 |
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",$todaytime)转换为日期。
3.php中时间戳转换为日期,并按照时间显示不同的内容,如刚刚,分钟前,小时前,今天,昨天等
/*时间转换函数*/
代码如下 | 复制代码 |
function transTime($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
