I want to store the current date generated from PHP into MongoDB collection as an ISO date formate.
ISODate("2012-11-02T08:40:12.569Z")
However I am not able to generate such Kind of date in php which will be stored in MongoDB as an ISODate format.
This is what I ve done.
$d = new MongoDate(time());
echo $d;
and it is outputting something like,
0.00000000 1353305590
which is not the format I need. How to do this?
You can specify a particular date by passing an ISO-8601 date string with a year within the inclusive range 0 through 9999 to the new Date() constructor or the ISODate() function. These functions accept the following formats: new Date("<YYYY-mm-dd>") returns the ISODate with the specified date.
The recommended way to store dates in MongoDB is to use the BSON Date data type. The BSON Specification refers to the Date type as the UTC datetime and is a 64-bit integer. It represents the number of milliseconds since the Unix epoch, which was 00:00:00 UTC on 1 January 1970.
MongoDB will store date and time information using UTC internally, but can easily convert to other timezones at time of retrieval as needed.
You could run the __toString
function, or use the sec
field
__toString
will return a timestamp in usecs, which you can pass to date()
after separating the seconds from milliseconds - read here: http://us1.php.net/manual/en/mongodate.tostring.php
OR, I personally prefer to have mongodb return just the seconds, which can be plugged directly into date()
- read here: http://php.net/manual/en/class.mongodate.php
Also, if you're generating a MongoDate() for right now, you don't need to specify time();
In order to return an isodate, you need to do this:
echo date(DATE_ISO8601, (new MongoDate())->sec);
...
$exampleDate = new MongoDate();
echo date(DATE_ISO8601, $exampleDate->sec);
EDIT: To save your ISO date, you need to do the following:
$mongoDateObject = new MongoDate(strtotime("2012-11-02T08:40:12.569Z"));
