Przykład #1 DateTime::setTimestamp() example

Styl obiektowy


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

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

Styl proceduralny


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

date_timestamp_set($date, 1171502725);

If your PHP version is lower than 5.3 then you can use this class to be able to use the functions "setTimestamp" and "getTimestamp":



<?php



class MyDateTime extends DateTime

{

    public function setTimestamp( $timestamp )

    {

        $date = getdate( ( int ) $timestamp );

        $this->setDate( $date['year'] , $date['mon'] , $date['mday'] );

        $this->setTime( $date['hours'] , $date['minutes'] , $date['seconds'] );

    }

    

    public function getTimestamp()

    {

        return $this->format( 'U' );

    }

}



$date = new MyDateTime();

$date->setTimestamp( $someTimestamp );



echo $date->format( 'd/m/Y H:i:s' );



?>

When the exact time is important then it is important to note the difference between this and the UnixTimeStamp. The function will change the timestamp if necessary to take into account the daylight savings time.

e.g. Working with the 'Europe/London' timezone and setting the DateTime object to a timestamp of 1288486753 will result in the function automatically altering it to 1288490353.

This is because it is taking the fall time instead of the summer time (they will both be Sun, 31-Oct-2010 01:X:Y (I didn't check the hour and minute)).

Sincerely,

Aouie
