I am using the following code:
$input = new DateTime(filter_input(INPUT_GET, 'date'));
$input->modify('midnight');
echo $input->format(DateTime::RFC3339) . "
";
$end = $input;
$end->modify('+3 hours');
echo $input->format(DateTime::RFC3339) . "
";
echo $end->format(DateTime::RFC3339) . "
";
Which is giving the following output:
2016-02-01T00:00:00-5:00
2016-02-01T03:00:00-5:00
2016-02-01T03:00:00-5:00
Shouldn't the output on line two be the same as the first?
From what I understand to assign a variable by reference you need to use $a = &$b
, so what I am using ($a = $b
) should be by value. So an function called on $end
should not modify $input
as well, correct? What am I missing?
