PHP获取日期一周前 - php get date a week ago

php get date a week ago

本文关键字：一周取日期获取 PHP | 更新日期: 2023-09-27

我试图为一周内的元素创建一个选择器。我得到一个时间戳像这样的Sun, 02 Jun 2013 22:05:00 GMT，但选择器不应该受到时间

的影响

如

<?
$curdate = date( 'D, d M Y H:I:s' );
$olddate = "Sun, 02 Jun 2013 22:05:00 GMT";
if($curdate < $olddate){
    // Date is with in a week
} else {
    // Date is older then a week
}

但是在这种情况下，它不应该受到每天在线时间的影响。

PHP的strtotime()函数就是你要找的。

例如:

echo date('jS F Y H:i.s', strtotime('-1 week'));

您可以在strtotime()函数中输入许多不同的字符串，例如:

strtotime('yesterday');
strtotime('-2 days ago');
strtotime('+5 days');

您应该只在比较日期之外创建日期。之后，您应该创建给定日期Sun, 02 Jun 2013 22:05:00 GMT的时间戳，并且应该将其转换为仅包含日期的日期字符串。然后从这个....创建另一个时间戳

如果你明白我的意思…这应该可以工作:

<?php
    // First create the date
    $date = 'Sun, 02 Jun 2013 22:05:00 GMT';
    // To a timestamp
    $t_date = strtotime($date);
    // Noew remove the seconds: First create a new date, with a timestamp of the give date.
    // After that create a datestring with only the date
    $date = date("jS F Y", $t_date);
    // And create a new timestamp
    $t_date = strtotime($date);
    // One week back: time - 60 seconds * 60 minutes * 24 hours * 7 days * -1 to get backwards
    // And we only create a date of this
    $weekback = date('jS F Y', time() + (60 * 60 * 24 * -7) );
    // Create a timestamp
    $t_weekback = strtotime($weekback);
    // Debug
    echo "Date: $date<br/>Date (UTC): $t_date<br/>";
    echo "Last week: $weekback<br/>Last week (UTC): $t_weekback<br/>";
    if ($t_date <= $t_weekback) {
        //Date is older then a week
        echo "Outside a week: last week($t_date) <= The date($t_weekback)";
    }else{
         //Date is within a week
         echo "Within a week: $t_date > $t_weekback";
    }
?>

当您使用PHP>= 5.3时，您可以使用以下命令:

<?php
$date     = new DateTime('Sun, 02 Jun 2013 22:05:00 GMT');
$interval = new DateInterval('P1W');
if(new DateTime() < $date->add($interval)){
    //date is with in a week
}{
    //date is older then a week
}
