PHP输出时间差函数

<?php  <BR>date_default_timezone_set('PRC'); //默认时区  <BR>echo "今天:",date("Y-m-d",time()),"<br>";  <BR>echo "今天:",date("Y-m-d",strtotime("18 june 2008")),"<br>";  <BR>echo "昨天:",date("Y-m-d",strtotime("-1 day")), "<br>";  <BR>echo "明天:",date("Y-m-d",strtotime("+1 day")), "<br>";  <BR>echo "一周后:",date("Y-m-d",strtotime("+1 week")), "<br>";  <BR>echo "一周零两天四小时两秒后:",date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds")), "<br>";  <BR>echo "下个星期四:",date("Y-m-d",strtotime("next Thursday")), "<br>";  <BR>echo "上个周一:".date("Y-m-d",strtotime("last Monday"))."<br>";  <BR>echo "一个月前:".date("Y-m-d",strtotime("last month"))."<br>";  <BR>echo "一个月后:".date("Y-m-d",strtotime("+1 month"))."<br>";  <BR>echo "十年后:".date("Y-m-d",strtotime("+10 year"))."<br>";  <BR>?> <BR>

在学习PHP 的时候，经常会用到获取现在之前或之后，某个时间段的日期。现在已经进行收集，大家同时也可以进行扩展丰富

//获取当天的星期（1-7）<BR>function GetWeek($times)<BR>{<BR>    $res = date('w', strtotime($times));<BR>    if($res==0)<BR>       $res=7;<BR>    return $res;<BR>}<BR>//获取当天时间<BR>function GetTime($times)<BR>{<BR>    $res = date('H:i', strtotime($times));<BR>    return $res;<BR>}<BR>//获取现在过几月的的时间<BR>function GetMonth($Month,$type='l')<BR>{<BR>    if(!strcmp($type,'b'))<BR>      $res=date("Y-m-d H:i:s",strtotime("-$Month months"));<BR>    if(!strcmp($type,'l'))<BR>      $res=date("Y-m-d H:i:s",strtotime("+$Month months"));<BR>    return $res;<BR>}<BR>//获取当前时间<BR>function GetCurrentDateTime()<BR>{<BR>    $res=date("Y-m-d H:i:s",time());<BR>    return $res;<BR>}<BR>//获取当前时间隔几小时之前或之后的时间<BR>function GetDiffHours($hours,$type='l')<BR>{<BR>  if(!strcmp($type,'b'))<BR>     $res=date("Y-m-d H:i:s",strtotime("-$hours hour"));<BR>  if(!strcmp($type,'l'))<BR>     $res=date("Y-m-d H:i:s",strtotime("+$hours hour"));<BR>  return $res;     <BR>}<BR>//间隔几分钟之前或之后的时间<BR>function GetDiffMinute($Minute,$type='l')<BR>{<BR>  if(!strcmp($type,'b'))<BR>     $res=date("Y-m-d H:i:s",strtotime("-$Minute minute"));<BR>  if(!strcmp($type,'l'))<b>/本文来源gao@!dai!ma.com搞$$代^@码5网@</b><strong>搞代gaodaima码</strong><BR>     $res=date("Y-m-d H:i:s",strtotime("+$Minute minute"));<BR>  return $res;     <BR>}<BR>//间隔几秒之前或之后的时间<BR>function GetDiffSec($sec,$type='l')<BR>{<BR>  if(!strcmp($type,'b'))<BR>     $res=date("Y-m-d H:i:s",strtotime("-$sec second"));<BR>  if(!strcmp($type,'l'))<BR>     $res=date("Y-m-d H:i:s",strtotime("+$sec second"));<BR>  return $res;     <BR>}</P><P>//间隔几个星期之前或之后的时间<BR>function GetDiffWeek($Week,$type='l')<BR>{<BR>  if(!strcmp($type,'b'))<BR>     $res=date("Y-m-d H:i:s",strtotime("-$Week week"));<BR>  if(!strcmp($type,'l'))<BR>     $res=date("Y-m-d H:i:s",strtotime("+$Week week"));<BR>  return $res;     <BR>}<BR>// 间隔几天之间的时间<BR>function GetDiffDays($days,$type='l')<BR>{<BR>  if(!strcmp($type,'b'))<BR>     $res=date("Y-m-d H:i:s",strtotime("-$days day"));<BR>  if(!strcmp($type,'l'))<BR>     $res=date("Y-m-d H:i:s",strtotime("+$days day"));<BR>  return $res;     <BR>}<BR>//间隔几年之前或之后的时间<BR>function GetDiffYears($year,$type='l')<BR>{<BR>  if(!strcmp($type,'b'))<BR>     $res=date("Y-m-d H:i:s",strtotime("-$year year"));<BR>  if(!strcmp($type,'l'))<BR>     $res=date("Y-m-d H:i:s",strtotime("+$year year"));<BR>  return $res;     <BR>}<BR>
