strtotime返回虚假日期

Question

I have a problem with strtotime function in php, i'm trying to convert mm-dd-yyyy to yyyy-mm-dd. The date is entered on the text box and on submit it should save the date to the database. the problem is it returns a wrong date(1970-01-01) each time,which means my code isn't taking the variable i use to store the date, My code is:

//dateconvert
$submitdate = date($_POST['date']);
$date   = date("Y-m-d", strtotime($submitdate));

//storeindb
$query ="INSERT INTO ticket SET date = '$date'";
$result = mysql_query($query);

I'm a newbie,please help.

Answer 1

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.

You need to use the forward slash separator for mm/dd/yyyy formats.
