You do not compare dates. You are comparing strings. In the world of string comparisons, '09 / 17/2015 '> '01 / 02/2016' because '09'> '01'. You need to either set the date in a comparable string format or compare DateTime objects that are comparable.
<?php $date_now = date("Ymd"); // this format is string comparable if ($date_now > '2016-01-02') { echo 'greater than'; }else{ echo 'Less than'; }
Demo
or
<?php $date_now = new DateTime(); $date2 = new DateTime("01/02/2016"); if ($date_now > $date2) { echo 'greater than'; }else{ echo 'Less than'; }
