Stile orientato agli oggetti

<?php
$date 
= new DateTimeImmutable();
echo 
$date->format('U = Y-m-d H:i:s') . "\n";

$newDate $date->setTimestamp(1171502725);
echo 
$newDate->format('U = Y-m-d H:i:s') . "\n";
?>

The above examples will output something similar to:

1272508903 = 2010-04-28 22:41:43
1171502725 = 2007-02-14 20:25:25

Note that this is not the right way to initiate a \DateTimeImmutable object with a numeric Unix timestamp. 

<?php
// Wrong, despite the documention *kind of* alluding to it
$obj = \DateTimeImmutable::setTimestamp(time() - 1);

// Also won't work
$obj = new \DateTimeImmutable(time() - 1)

// Correct, works, clean single line
$obj = (new \DateTimeImmutable())->setTimestamp(time() - 1);
?>

... In fact, this is a non-static method and thus should not be called statically.

This function will not change the value of the DateTimeImmutable object as the method name might suggest. The object, after all, immutable.

<?php
   $dti
= new DateTimeImmutable();
   echo
$dti->getTimestamp(); // e.g. 123456789
  
$dti->setTimestamp(987654321);
   echo
$dti->getTimestamp(); // 123456789

  
$x = $dti->setTimestamp (987654321);
   echo
$x->getTimestamp(); // 987654321
?>
