数据库的时间 mydate与系统时间比较
如何判断是否大于24小时了?


回复讨论(解决方案)

用时间戳比较
24x3600 

time()+60*60*24

 mydate是什么格式,日期格式吗?用strtotime转换为unix时间轴,然后就参照楼上的方法做就好了,当前时间轴为:time()

$mydate="2013-10-14 09:29:48"; //$mydate="2013-10-10 09:29:48"
$mydate=strtotime($mydate);
echo $mydate."==";
$nowdate=time()+60*60*24;
echo $nowdate;
if($mydate>$nowdate){
echo ">";
}else{
echo " }
?>

为什么两种取值显示出来全是“

$mydate="2013-10-14 09:29:48";
$mydate=strtotime($mydate)+60*60*24;
echo $mydate."==";
$nowdate=time();
echo $nowdate;
if($mydate>$nowdate){
echo ">";
}else{
echo " }
?>
以上的应该是正确的吧

打酱油!
