You are notcomparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015> 01/02/2016because 09> 01. You need to either put your date in a comparable string format or compare DateTimeobjects which are comparable.
你不是在比较日期。您正在比较字符串。在字符串比较的世界中，09/17/2015>01/02/2016因为09> 01。您需要将日期放在可比较的字符串格式中，或者比较DateTime可比较的对象。
<?php
$date_now = date("Y-m-d"); // this format is string comparable
if ($date_now > '2016-01-02') {
echo 'greater than';
}else{
echo 'Less than';
}
Or
或者
<?php
$date_now = new DateTime();
$date2 = new DateTime("01/02/2016");
if ($date_now > $date2) {
echo 'greater than';
}else{
echo 'Less than';
}
