DateTime[Immutable]::createFromTimestamp(float) misses support for 64bit integers or 32bit environments

Description

The following code:

<?php

$dt = DateTime::createFromFormat('U', '2147483647');
var_dump($dt);

$dt = $dt->modify('+1 second');
var_dump($dt);

$ts = $dt->format('U');
$tsf = (float)$ts;
var_dump($ts, $tsf);

$dt2 = DateTime::createFromTimestamp($tsf);

Resulted in this output:

object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2038-01-19 03:14:07.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "+00:00"
}
object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2038-01-19 03:14:08.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "+00:00"
}
string(10) "2147483648"
float(2147483648)

Fatal error: Uncaught DateRangeError: DateTime::createFromTimestamp(): Argument #1 ($timestamp) must be a finite number between -2147483648 and 2147483647.999999, 2.14748e+9 given 

But I expected this output instead:

object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2038-01-19 03:14:07.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "+00:00"
}
object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2038-01-19 03:14:08.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "+00:00"
}
string(10) "2147483648"
float(2147483648)
object(DateTime)#2 (3) {
  ["date"]=>
  string(26) "2038-01-19 03:14:08.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "+00:00"
}

Operating System

32bit environment

Commencez par le point d’entrée DateTime::createFromTimestamp() et reproduisez l’exemple dans un environnement 32 bits, en vous concentrant sur la valeur float 2147483648. C’est terminé lorsque cette valeur est acceptée et produit le DateTime attendu 2038-01-19 03:14:08 au lieu d’un DateRangeError.
