Why does DateTime::createFromFormat() fails and returns a boolean in my second example?

Question

When I run this the first one is correctly created into a date. The second one fails, returning a boolean and so I cannot format. Is the time out of range?

Answer 1

In addition to the other answers, for standard formats understood by DateTime you don't need to create from a format:

$startDate = "2015-05-12 15:49:06.821289";
$start = new DateTime($startDate);
echo $start->format('m/d/y');
