【PHP】时间差计算时间比较时间计算

作者:烨磊 / 发布于2016/7/18/ 767

比较两个绝对时间的大小
<?php   
$zero1=date(“y-m-d h:i:s”);   
$zero2=”2010-11-29 21:07:00′;   
echo “zero1的时间为：”.$zero1.””;   
echo “zero2的时间为：”.$zero2.””;   
if(strtotime($zero1)<strtotime($zero2)){   
echo “zero1早于zero2′;   
}else{   
echo “zero2早于zero1′;   
}   
?>  


 
倒计时小程序
<?php   
$zero1=strtotime (date("y-m-d h:i:s")); //当前时间  ,注意H 是24小时 h是12小时 
$zero2=strtotime ("2014-1-21 00:00:00");  //过年时间，不能写2014-1-21 24:00:00  这样不对 
$guonian=ceil(($zero2-$zero1)/86400); //60s*60min*24h   
echo "离过年还有<strong>$guonian</strong>天！";   
?>  

 
  
 

<?php
//PHP计算两个时间差的方法 
$startdate="2010-12-11 11:40:00";
$enddate="2012-12-12 11:45:09";
$date=floor((strtotime($enddate)-strtotime($startdate))/86400);
$hour=floor((strtotime($enddate)-strtotime($startdate))%86400/3600);
$minute=floor((strtotime($enddate)-strtotime($startdate))%86400/60);
$second=floor((strtotime($enddate)-strtotime($startdate))%86400%60);
echo $date."天";
echo $hour."小时";
echo $minute."分钟";
echo $second."秒";
 
?>
