Date Calculation in PHP

Question

I need to create a code in c# to check either the date picked is tomorrow onwards or has passed by today.

My idea is $checkDateInPass will get the current date minus with 1 day. Thus when a user enter a date either it was on THAT date or afterwards, $checkPass will fly a green flag to say that it passed the first validation. If it was otherwise, it will turned into an error.

Here's the code for date validation:

$checkDateInPass = date('d/m/Y',strtotime("-1 days"));
if($checkInDate > $checkDateInPass)
{
    $checkPass += 1;
}
else
{
    $message = "Please pick a proper date to check in.";
    echo "<script type='text/javascript'>alert('$message');</script>";
}

Based on the above written code it work just fine IF I picked the check in date in the same month, but if I picked the check in date on the next month other than the current month, it doesn't work as expected.

Here's an example, lets say that $checkDateInPass is 27/12/2016:

A: I picked 29/12/2016 for first date, and 04/01/2017 for second date. It worked just fine.

B: I picked 04/01/2017 for first date, and 07/01/2017 for second date. It turns out to be wrong.

Is there any other IF statement to be considered for this statement?

It looks like you're comparing strings containing formatted time, not actual times. You can compare the time this way:

$checkDateInPass = date('d/m/Y',strtotime("-1 days"));
if(strtotime($checkInDate) > strtotime($checkDateInPass))
{
    $checkPass += 1;
}
else
{
    $message = "Please pick a proper date to check in.";
    echo "<script type='text/javascript'>alert('$message');</script>";
}
