到达截止日期时显示错误的罚款

Question

当达到到期日时，而不是将罚款显示为25，它将显示0.当我在截止日期之后移动日期时，它将显示25。

这是我的代码。

$Borrow_Query = mysql_query("SELECT a.*, b.*, c.*, d.*, e.* FROM tblUser a, tblBorrowed b, tblResources c, tblCategory d, tblResourcesType e WHERE a.User_ID = '".$_GET['User_ID']."' AND b.User_ID = a.User_ID AND b.Accession_No = c.Accession_No AND c.Category_ID = d.Category_ID AND c.Type_ID = e.Type_ID ");
    while ($Show = mysql_fetch_array($Borrow_Query)){

    $DueDate = $Show['Due_Date'];

    $timezone = "Asia/Manila";
    if(function_exists('date_default_timezone_set')){
        date_default_timezone_set($timezone);   

        $CURTIME2 = date('h:i a');
        $CURDATE2 = date('F d,Y');
    }

    $AllowedTime_Query = mysql_query("SELECT * FROM tblAllowed_Days");
    $AllowedTime_Row = mysql_fetch_array($AllowedTime_Query);
    $Time = $AllowedTime_Row['Time'];

    $Penalty_Query = mysql_query("SELECT * FROM tblPenalty");
    $Penalty_Row = mysql_fetch_array($Penalty_Query);
    $Fine = $Penalty_Row['Penalty'];

    $Date_Time = $CURDATE2.' '.$Time;

    if($Date_Time >= $DueDate){
        $Fines = round((float)(strtotime($Date_Time) - strtotime($DueDate)) / (60 * 60 * 24) * ($Fine));
    }else{
        $Fines = 'No Penalty';  
    }
?>

Answer 1

使用strtotime功能在PHP中进行日期比较。

ex，if(strtotime($Date_Time) > strtotime($DueDate)){ ...

Answer 2

好的，所以这个有效，但我不确定你试图从$Fines获得什么，因为你把时间差乘以我认为的int然后四舍五入呢？

无论如何，你去，玩的东西。

<?php
$CURDATE2  = '2016-10-10';
$Time      = '12:12:12';
$DueDate   = '2016-09-09 12:12:12';
$Date_Time = $CURDATE2.' '.$Time;
$Fine      = 20;

if( strtotime( $Date_Time ) > strtotime( $DueDate ) )
{
  $Fines = round( (float) (strtotime( $Date_Time ) - ( strtotime( $DueDate ) ) / ( 60 * 60 * 24 ) * ( $Fine ) ), 2 );
}
else
{
  $Fines = 'No Penalty';  
}
echo $Fines;
