PHP: Date larger than current date
提问by Cameron
I have this code:
我有这个代码：
$curdate = '22-02-2011';
$mydate = '10-10-2011';
if($curdate > $mydate)
{
echo '<span class="status expired">Expired</span>';
}
This would echo expired BUT shouldn't because $mydate is in the future and therefore smaller than the $curdate but PHP is looking at JUST the first two numbers 22 and 10 instead of the whole string. How can I fix this?
这会回显过期但不应该，因为 $mydate 是未来，因此小于 $curdate 但 PHP 只查看前两个数字 22 和 10 而不是整个字符串。我怎样才能解决这个问题？
Thanks
谢谢

Try converting them both to timestamps first, and then compare two converted value:
尝试先将它们都转换为时间戳，然后比较两个转换后的值：
$curdate=strtotime('22-02-2011');
$mydate=strtotime('10-10-2011');
if($curdate > $mydate)
{
echo '<span class="status expired">Expired</span>';
}
This converts them to the number of seconds since January 1, 1970, so your comparison should work.
这会将它们转换为自 1970 年 1 月 1 日以来的秒数，因此您的比较应该有效。

The problem is that your current variables are strings, and not time variables.
问题是您当前的变量是字符串，而不是时间变量。
Try this out:
试试这个：
$curdate = strtotime('22-02-2011');
$mydate = strtotime('10-10-2011');

$row_date = strtotime($the_date);
$today = strtotime(date('Y-m-d'));
if($row_date >= $today){

Use the PHP date/time classes to convert these string representations into something you can directly compare using getTimestamp() to compare the UNIX times.
使用 PHP 日期/时间类将这些字符串表示形式转换为您可以使用 getTimestamp() 直接比较的内容，以比较 UNIX 时间。
If you're sure all your dates are in this format, you can string slice them into YYYY-MM-DD, and a string comparison will function correctly then.
如果您确定所有日期都采用这种格式，则可以将它们字符串切片为 YYYY-MM-DD，然后字符串比较将正常运行。

$currentDate = date('Y-m-d');
$currentDate = date('Y-m-d', strtotime($currentDate));
$startDate = date('Y-m-d', strtotime("01/09/2019"));
$endDate = date('Y-m-d', strtotime("01/10/2022"));
if (($currentDate >= $startDate) && ($currentDate <= $endDate)) {
echo "Current date is between two dates";
} else {
echo "Current date is not between two dates";
}

it's VERY simple
这很简单
$curdate = '2011-02-22';
$mydate = '2011-10-10';
if($curdate > $mydate)
{
echo '<span class="status expired">Expired</span>';
}
