Check if any date is older than 5 years - laravel

Question

I am trying to figure out the best way to achieve something. I am looping through some data that involves a group of dates
foreach ($fields['dates'] as $key => $dates) {
$fields['dates'][$key]['datestring'] = Carbon::createFromFormat(
'dmY',
$dates['datestring']
);
var_dump($fields['dates'][$key]['datestring']);
}
The var_dump above produces something like the following
object(Carbon\Carbon)#330 (3) { ["date"]=> string(26) "2019-08-08 12:41:00.000000" ["timezone_type"]=> int(3) ["timezone"]=> string(3) "UTC" } object(Carbon\Carbon)#328 (3) { ["date"]=> string(26) "1987-08-08 12:41:00.000000" ["timezone_type"]=> int(3) ["timezone"]=> string(3) "UTC" }
So above this, I have created a variable to identify whether at least one of the dates is more than 5 years ago. I have also created a date object for today.
$moreThanFiveYears = false;
$now = Carbon::now();
Now what I am trying to figure out is how I perform the actual check? When I try the above, it complains because $now is not the same format as my other dates. I have tried adding a format to it, but it produces only something like 20190219 and not the additional data the original dates produce.
So how can I loop all my dates to ensure at least one is greater than 5 years?
Thanks

Answer 1

get five years ago by subYears() and compare them by greaterThan().
$fiveYearsAgo = Carbon::now()->subYears(5);
foreach ($fields['dates'] as $key => $dates) {
$fields['dates'][$key]['datestring'] = Carbon::createFromFormat(
'dmY',
$dates['datestring']
);
if ($fields['dates'][$key]['datestring']->greaterThan($fiveYearsAgo)) {
$moreThanFiveYears = false;
}
}

Try out this.
<?
$check_date = '2019-12-18 18:20:40';
if(strtotime($check_date) < strtotime('-5 year')){
echo "YES";
}else{
echo "NO";
}
?>

Since you are using Carbon, you can make use of the difference methods, which allow you to easily calculate the difference between two dates, in any unit:
diffInSeconds()
diffInMinutes()
diffInHours()
diffInDays()
diffInYears()
# existing date
$old = Carbon::parse("2010-01-20 12:00:00");
# current date
$now = Carbon::now();
# find the difference
$diff = $old->diffInYears($now);
# test your difference
if($diff > 5) {
echo "date is older than 5 years";
}
Note: since you are calculating difference, the order of the comparables does not matter - the answer would be the same in both cases:
$diff = $old->diffInYears($now);
$diff = $new->diffInYears($old);
