PHP 7.0.6 Released

    The MongoDate class

    (PECL mongo >=0.8.1)

    Warning

    This extension that defines this class is deprecated. Instead, the MongoDB extension should be used. Alternatives to this class include:

    Introduction

    Represent date objects for the database. This class should be used to save dates to the database and to query for dates. For example:

    Example #1 Storing dates with MongoDate

    <?php

    // save a date to the database
    $collection->save(array("ts" => new MongoDate()));

    $start = new MongoDate(strtotime("2010-01-15 00:00:00"));
    $end = new MongoDate(strtotime("2010-01-30 00:00:00"));

    // find dates between 1/15/2010 and 1/30/2010
    $collection->find(array("ts" => array('$gt' => $start, '$lte' => $end)));

    ?>

    MongoDB stores dates as milliseconds past the epoch. This means that dates do not contain timezone information. Timezones must be stored in a separate field if needed. Second, this means that any precision beyond milliseconds will be lost when the document is sent to/from the database.

    For showing a human readable MongoDate, you can use something like this:

    <?php
    date    ('Y-M-d h:i:s', $yourDate->sec);
    ?>

    I wanted a way to check the age of a record.  This code will calculate the time between the creation date of the record, and return the seconds.  I use it for caching pages similar to the max-age header in a browser.  If the record is older, than my limit it deletes itself.

    <?php
    function microtime_diff( $start, $end=NULL ) {
            if( !    $end ) {
                    $end= microtime();
            }
            list(    $start_usec, $start_sec) = explode(" ", $start);
            list(    $end_usec, $end_sec) = explode(" ", $end);
                $diff_sec= intval($end_sec) - intval($start_sec);
                $diff_usec= floatval($end_usec) - floatval($start_usec);
            return     floatval( $diff_sec ) + $diff_usec;
    }

    microtime_diff($cache['stamp']->sec);
    ?>
