Question

PostQopen和PostQClose是日期时间列。我需要一个php if语句来检查当前日期时间是否在PostQopen和PostQClose列之间。

$now = date('Y-m-d H:i:s');

if($rows['PostQopen'] >= '$now' && $rows['PostQClose'] < '$now' ){

echo "TRUE";

} else { 

echo "FALSE";

};

Answer 1

使用DateTime。

$date = new DateTime("now");
$PostQopen = new DateTime($rows['PostQopen']);
$PostQClose = new DateTime($rows['PostQClose']);

if($PostQopen >= $date && $PostQClose <=$now){
 // do ur stuff
}

Answer 2

从$ now中删除单引号并使用strtotime()。如果仍然没有strtotime()，则代码可以正常运行，因为如果它位于compare time中，您可以datetime format。

if(strtotime($rows['PostQopen']) >= strtotime($now) && strtotime($rows['PostQClose']) < strtotime($now) )
{
   echo "TRUE";
} 
else
{ 
   echo "FALSE";
}

Answer 3

找出使用DateTime之间的函数在这里：

function dateIsBetween($from, $to, $date="now") {
    $date = new \DateTime($date);
    $from= new \DateTime($from);
    $to = new \DateTime($to);
    if ($date >= $from && $date <= $to) {
        return true;
    }
    return false;
}

使用功能

dateIsBetween('2016-02-24', '2016-02-26', '2016-02-25'); //would return true
dateIsBetween('2016-02-24', '2016-02-26', 'now'); //would return true if the current date would be between specified to, from
dateIsBetween('2016-02-24', '2016-02-26'); //would return true if the current date would be between specified to, from

Answer 4

$now = date('Y-m-d H:i:s');

if(strtotime($rows['PostQopen']) >= strtotime('$now') && strtotime($rows['PostQClose']) < strtotime('$now') ){

echo "TRUE";

} else { 

echo "FALSE";

};

检查这是否有效，strtotime将给定时间转换为毫秒格式，它应该工作

Answer 5

代替原生date（）函数，最好使用DateTime对象，这是您的情况示例

现在（）在PostQopen和PostQclose之间

$now = new DateTime(date('Y-m-d H:i:s'));
$DateRange = array(
    'PostQopen'     => new DateTime($rows['PostQopen']),
    'PostQClose'    => new DateTime($rows['PostQClose']),
);
if (($DateRange['PostQopen'] <= $now) && ($DateRange['PostQClose'] > $now)) {
    echo "TRUE";
} else {
    echo "FALSE";
}

php if语句检查当前日期时间是否在2个日期时间列之间
