I unfortunately can't use DateTime() as the server this project is on is running PHP v.5.2.
the line in question:
$aptnDate2 = date('Y-m-d', $_POST['nextAppointmentDate']);
throws the following error:
Notice: A non well formed numeric value encountered
so I var dump to make sure it's well formatted..
var_dump($_POST['nextAppointmentDate']);
string(10) "12-16-2013"
The php docs state that it takes a timestamp not a string. but when I do:
date('Y-m-d', strtotime($_POST['nextAppointmentDate']));
and then var_dump the result, I get this:
string(10) "1969-12-31"
why can I not format a date with this date value and strtotime()?
thanks!
From the documentation for strtotime():
Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.
In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.
Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:
$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16
