copied!<p>You could create your own <code>DateTime</code> class that extends the default <code>DateTime</code> and hence change the behaviour:</p> <pre><code><?php class CustomDateTimeVariables { public static $date = 'now'; } class CustomDateTime extends DateTime { public function __construct($time = null, DateTimeZone $timezone = null) { if ($time === null) { $time = CustomDateTimeVariables::$date; } if ($timezone !== null) { parent::__construct($time, $timezone); } else { parent::__construct($time); } } } CustomDateTimeVariables::$date = '2010-01-01'; $datetime1 = new CustomDateTime(); CustomDateTimeVariables::$date = '2010-01-02'; $datetime2 = new CustomDateTime(); var_dump($datetime1->Format('Y-m-d H:i:s')); //"2010-01-01 00:00:00" var_dump($datetime2->Format('Y-m-d H:i:s')); //"2010-01-02 00:00:00" ?> </code></pre> <p><a href="http://codepad.org/jyPW0lJP" rel="nofollow"><strong>DEMO</strong></a></p> <p>This way you can also set the default time very easily (check <code>CustomDateTimeVariables</code>):</p> <pre><code><?php class CustomDateTimeVariables { public static $date = 'now +120 hours'; } class CustomDateTime extends DateTime { public function __construct($time = null, DateTimeZone $timezone = null) { if ($time === null) { $time = CustomDateTimeVariables::$date; } if ($timezone !== null) { parent::__construct($time, $timezone); } else { parent::__construct($time); } } } $datetime = new CustomDateTime(); var_dump($datetime->Format('Y-m-d H:i:s')); //"2013-10-29 13:37:39" ?> </code></pre> <p><em>..and when it goes live, you can simply change the default back to <code>now</code>.</em></p>
