PHP日期与MySQL日期字段的比较

Question

I'm trying to compare the current date with a date field returned by a MySQL query called "expiry_date". This field is a date field formatted as YYYY-MM-DD I'm using If Else, to initialize a variable with the result as follows:

$today = $expiry_date = date("d-M-Y", strtotime("now"));
if ($row['expiry_date'] > $today)
{
    $msg="Not Expired";
}
else
{
    $msg="Expired";
}

This doesn't appear to work and I would appreciate any suggestions on how to fix this.

Answer 1

$today = $expiry_date = new \Datetime();
$row_expiry_date = date_create_from_format('Y-m-d', $row['expiry_date']);
if ($row_expiry_date > $today)
{
     $msg="Not Expired";
} else {
     $msg="Expired";
}

Answer 2

You have two options, you can either format the dates the same and compare as strings

$today = $expiry_date = date("Y-m-d", strtotime("now"));
if ($row['expiry_date'] < $today)

or you can convert the row data to a unix timestamp for the comparison.

$today = $expiry_date = time();
if (strtotime($row['expiry_date']) < $today)

Answer 3

you have $today = $expiry_date = which should be $today = or $expiry_date =

$today = date("Y-m-d");

if (strtotime($row['expiry_date']) > $strtotime($today))
{
     echo "not expired";
} else {
    echo "expired";
}
