Others have already pointed out that strtotime() is a function and not a
method. I suggest that you learn the basics of object oriented
programming in PHP[2], even if you don't plan to write your own classes.
Furthermore it seems to be noteworthy that strtotime() parses strings in
the format 01/02/2015 as American dates, i.e. as Jan. 2, 2015.[1] If
you have to deal with European dates (d/m/Y), you would have to prepare
the date string before passing it to strtotime().
Regarding the sorting: you don't want to to strcmp() the results of
strtotime(), because the results are numbers. The simplest and most
efficient solution is to subtract these numbers:
$result = strtotime($a->getField('Test_Date'))
- strtotime($b->getField('Test_Date'));
