$event['date']
and this display's in this format:
并且此显示器采用以下格式：
2013-07-31for example.
2013-07-31例如。
Now, what I need to do is to check if this date is a past date to the current date.
现在，我需要做的是检查这个日期是否是当前日期的过去日期。
How can I do this?
我怎样才能做到这一点？

You can compare the dates with PHP's DateTimeclass:
您可以将日期与 PHP 的DateTime类进行比较：
$date = new DateTime($event['date']);
$now = new DateTime();
if($date < $now) {
echo 'date is in the past';
}
Note: Using DateTimeclass is preferred over strtotime()since the latter will only work for dates before 2038. Read more about the Year_2038_problem.
注意：使用DateTimeclass 是首选，strtotime()因为后者仅适用于 2038 年之前的日期。阅读有关Year_2038_problem 的更多信息。

You can use strtotime()and time():
您可以使用strtotime()和time()：
if (strtotime($event['date']) < time()) {
// past date
}

$date = new DateTime("09/14/2017");
$now = new DateTime();
print_r($date);
print_r($now);
if($date < $now) {
echo 'date is in the past';
}

输出将是
DateTime Object

[timezone_type] => 3
[timezone] => UTC
)
DateTime Object
(
[date] => 2017-09-14 07:12:52.000000

解决方案
$Date1 = strtotime(date('Y-m-d', strtotime('2017-09-15') ) ).' ';
$Date2 = strtotime(date('Y-m-d'));
if($Date1 < $Date2) {
echo 'date is in the past';
}

if (time() > strtotime($event['date']))
{
// current date is greater than 2013-07-31
}
strtotimeparses the date sting using these rules.
