How can I check if the current date/time is past a set date/time?
PhpDateDatetimePhp Problem Overview
I'm trying to write a script that will check if the current date/time is past the 05/15/2010 at 4PM
How can I use PHP's date() function to perform this check?

Solution 1 - Php
Since PHP >= 5.2.2 you can use the DateTime class as such:
if (new DateTime() > new DateTime("2010-05-15 16:00:00")) {
# current time is greater than 2010-05-15 16:00:00
# in other words, 2010-05-15 16:00:00 has passed
}
The string passed to the DateTime constructor is parsed according to these rules.
Note that it is also possible to use time and strtotime functions. See original answer.
Solution 2 - Php
There's also the http://de.php.net/DateTime">DateTime</a> class which implements a function for comparison operators.
// $now = new DateTime();
$dtA = new DateTime('05/14/2010 3:00PM');
$dtB = new DateTime('05/14/2010 4:00PM');
if ( $dtA > $dtB ) {
echo 'dtA > dtB';
}
else {
echo 'dtA <= dtB';
}
Solution 3 - Php
Check PHP's strtotime-function to convert your set date/time to a timestamp: http://php.net/manual/en/function.strtotime.php
If strtotime can't handle your date/time format correctly ("4:00PM" will probably work but not "at 4PM"), you'll need to use string-functions, e.g. substr to parse/correct your format and retrieve your timestamp through another function, e.g. mktime.
Then compare the resulting timestamp with the current date/time (if ($calulated_timestamp > time()) { /* date in the future */ }) to see whether the set date/time is in the past or the future.
I suggest to read the PHP-doc on date/time-functions and get back here with some of your source-code once you get stuck.
Solution 4 - Php
date_default_timezone_set('Asia/Kolkata');
$curDateTime = date("Y-m-d H:i:s");
$myDate = date("Y-m-d H:i:s", strtotime("2018-06-26 16:15:33"));
if($myDate < $curDateTime){
echo "active";exit;
}else{
echo "inactive";exit;
}
