在PHP上转换为日期它不起作用

Question

I have the following code:

$date1 = (string)$_POST['convocatory_open_start_date']; // "30/04/2015"
$date2 = (string)$_POST['convocatory_open_end_date'];  // "31/05/2015"
$startDate = date('Y-m-d', strtotime($date1));
$endDate   = date('Y-m-d', strtotime($date2));

but I always get $startDate and $endDate 1970-01-01 Why???

Please Help I have like 3 hours in the same problem.

Thanks

Answer 1

The problem is that if you use / as a separator, strtotime will assume the format is m/d/Y. So it will not be able to convert it, and it defaults to 1970-01-01.

The easiest solution would be

$startDate = DateTime::createFromFormat('d/m/Y', $date1)->format('Y-m-d');
$endDate   = DateTime::createFromFormat('d/m/Y', $date2)->format('Y-m-d');
