PHP detect if between specified date and now() matched specified condition - php

Question

I want to know how to detect if a date range matched specified condition:
Expected results:
<?php
$start_date1 = '2016-05-06 00:00:00';
$start_date2 = '2016-01-06 00:00:00';
$result1 = is_date_range_exceeds_3_months($start_date1);
$result2 = is_date_range_exceeds_3_months($start_date2);
//lets say 'now' is '2016-06-06 00:00:00'
//Expected result of $result1 = false
//Expected result of $result2 = true
?>
(Please make correction to my question as I think this question is not in correct format/words)
Thanks!

Answer 1

You could use DateTime for this.
function is_date_range_exceeds_3_months($strDate)
{
$userDate = new \DateTime($strDate); // #todo: Check if is valid
$checkDate = new \DateTime(); // By default date seed is now
$checkDate->modify('+3 months'); // Set period
if($userDate > $checkDate) {
return true;
} else {
return false;
}
}
This is just a tip, sorry if it contains some typos.
Edit by OP:
function is_date_range_exceeds_x_months($month_limiter, $start_date) {
$userDate = new DateTime($start_date); // #todo: Check if is valid
$userDate = $userDate->format('Y-m-d H:i:s');
$checkDate = new DateTime(); // By default date seed is now
$checkDate->modify('-' . $month_limiter . ' months'); // Set period
$checkDate = $checkDate->format('Y-m-d H:i:s');
if ($userDate < $checkDate) {
return true;
} else {
return false;
}
}

<?php
$start_date1 = '2016-05-06 00:00:00';
$start_date2 = '2016-01-06 00:00:00';
$result1 = is_date_range_exceeds_3_months($start_date1);
$result2 = is_date_range_exceeds_3_months($start_date2);
//lets say 'now' is '2016-06-06 00:00:00'
function is_date_range_exceeds_3_months($start_date)
{
$lastdates=date('Y-m-d H:i:s', strtotime('-3 month'));
$current_dates=date("Y-m-d H:i:s");
echo 'currentdate'.$current_dates.'<br/>';
echo 'Lasytdate'.$lastdates.'<br/>';
if (($start_date > $lastdates) && ($start_date < $current_dates))
{
return true;
}
else
{
return false;
}
}
//Expected result of $result1 = false
//Expected result of $result2 = true
?>
