DateTime::setTimestamp - Sets the date and time based on an Unix timestamp

       Object oriented style

SYNOPSIS

       public DateTime DateTime::setTimestamp (int  $unixtimestamp)

DESCRIPTION

       Procedural style
       DateTime date_timestamp_set (DateTime  $object, int  $unixtimestamp)

	Sets the date and time based on an Unix timestamp.

PARAMETERS

	      o $object
		-Procedural style only: A DateTime object returned by date_create(3). The function modifies this object.

	      o $unixtimestamp
		- Unix timestamp representing the date.

RETURN VALUES

	Returns the DateTime object for method chaining or FALSE on failure.

EXAMPLES

       Example #1

	      DateTime.setTimestamp(3) example

	      Object oriented style

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

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

	      Procedural style

	      <?php
	      $date = date_create();
	      echo date_format($date, 'U = Y-m-d H:i:s') . "
";

	      date_timestamp_set($date, 1171502725);
	      echo date_format($date, 'U = Y-m-d H:i:s') . "
";
	      ?>

	      The above examples will output something similar to:

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

NOTES

	Using the Unix timestamp format to construct a new DateTime object is an alternative when using PHP 5.2, as shown in the example below.

       Example #2

	      DateTime.setTimestamp(3) alternative in PHP 5.2

	      <?php
	      $ts = 1171502725;
	      $date = new DateTime("@$ts");
	      echo $date->format('U = Y-m-d H:i:s') . "
";
	      ?>

	      The above example will output something similar to:

	      1171502725 = 2007-02-14 20:25:25

DateTime::diff - Returns the difference between two DateTime objects

       Object oriented style

SYNOPSIS

       public DateInterval DateTime::diff (DateTimeInterface  $datetime2, [bool  $absolute = false])

DESCRIPTION

       DateInterval DateTimeImmutable::diff (DateTimeInterface	$datetime2, [bool  $absolute = false]) DateInterval DateTimeInterface::diff (Date-
       TimeInterface  $datetime2, [bool  $absolute = false])

       Procedural style
       DateInterval date_diff (DateTimeInterface  $datetime1, DateTimeInterface  $datetime2, [bool  $absolute = false])

	Returns the difference between two DateTimeInterface objects.

PARAMETERS

	      o $datetime
		- The date to compare to.

	      o $absolute
		- Should the interval be forced to be positive?

RETURN VALUES

	The DateInterval object representing the difference between the two dates or FALSE on failure.

EXAMPLES

       Example #1

	      DateTime.diff(3) example

	      Object oriented style

	      <?php
	      $datetime1 = new DateTime('2009-10-11');
	      $datetime2 = new DateTime('2009-10-13');
	      $interval = $datetime1->diff($datetime2);
	      echo $interval->format('%R%a days');
	      ?>

	      Procedural style

	      <?php
	      $datetime1 = date_create('2009-10-11');
	      $datetime2 = date_create('2009-10-13');
	      $interval = date_diff($datetime1, $datetime2);
	      echo $interval->format('%R%a days');
	      ?>

	      The above examples will output:

	      +2 days

       Example #2

	      DateTime object comparison

	      Note

		      As of PHP 5.2.2, DateTime objects can be compared using comparison operators.

	      <?php
	      $date1 = new DateTime("now");
	      $date2 = new DateTime("tomorrow");

	      var_dump($date1 == $date2);
	      var_dump($date1 < $date2);
	      var_dump($date1 > $date2);
	      ?>

	      The above example will output:

	      bool(false)
	      bool(true)
	      bool(false)
