PHP - Php Datetime Ago Function?

Hello!! i want to save datetimes into a mysql database. Their format is dd-mm-yy  hh:mm. I think mysql format for datetime is yy-mm-dd hh:mm..How can i convert them??

Hi Everyone,

Please have a look at this, and tell me if its right?
I am generating a sitemap for my website dynamically.

The date I am providing: 2012-02-24 11:56:09 and this is the output I am getting: 2012-02-24T11:56:09Z
now I am not sure of the Z at the end of the returned value.

I think I am looking for something similar to this: 2012-03-12T12:00:02+02:00

not to sure what I am doing wrong and where it gets the timezone from, I am guessing from the php config file.

any help would be much appreciated. thanks

My code:

Code: [Select]
<lastmod><?php echo $time->toAtom($post['Post']['modified']); ?></lastmod>

Hi, I'm a newbie here, and with PHP, and need some help with the datetime display.
I am wanting to utilize old Naval comms DTG (datetimegroup) format which is DDHHMM 3-digit Month 2-digit year.
The DDHHMM = Day (01 - 31) HH (hour 01 - 24) MM (minute 00 - 59)
What I need to do is to add the letter Z (meaning GMT, ZULU) like thus  DDHHMMZ FEB 11
How can I go about inserting that Z into this?

Tks in advance for any assist

Code: [Select]
OFXAdapter: Failed to parse request: Unable to parse an atomic field "OFXRequest.OFXRequest.SignOnMsgsRqUn.SignOnMsgsRqV1.SonRq.DtClient": field value "20101005091544.000[-4:EDT]" is not a valid (YYYYMMDDHHMMSS.XXX[gmt offset:tz name]) date.
I am trying to put together some PHP code to use the OFX standard to communicate with my bank in order to download my recent transactions. The standard details that in the sign-on request, the date and time must be included in the format listed above.

As you can see, I have the value in the exact same format as specified. So my question is this: is there something about GMT offset or TZ names that I am missing here?

I'm given something like this:
Sun Nov 06 2011 09:30:00 GMT-0500 (EST)

And i'm trying to turn that into
2011-11-06 09:30:00

I started by using explode and trying to loop through the day and month to figure it out, but that seems inefficient and overly complicated. Am i missing something?

Thanks

I have a function that receives two datetime values attached to the variables $start and $end.  These will be in the format 'Y-m-d H:i:s'.

For each of these values, I create a DateTime object to make the handling of them easier:
Code: [Select]
$startDT = DateTime::createFromFormat('Y-m-d H:i:s', $start);
$endDT = DateTime::createFromFormat('Y-m-d H:i:s', $end);

What I need to do now is ensure that the seconds of the $startDT value are always set to '00' and the seconds of the $endDT value are always set to '59'.

Is there an easy way to do this without having to extract the individual values for hours, minutes and seconds before reapplying them using the setTime function, adjusting the values accordingly?

Hello,

I am preparing $begin and $end for DatePeriod() but I can't get passed this error "getting the error Recoverable fatal error: Object of class DateTime could not be converted to string".

$today = date("Y-m-d");
$datestop=$_POST['datestop'];
//echo "$today<br /><br />$datestop<br /><br />";
$begin = new DateTime("$today");
$end = new DateTime("$datestop");

 

Hi all,
I have a loop that is modifying a DateTime object. It goes through X number of times and adds 1 day to the date time object and stores the modified object in an array. I use ->add(new DateInterval('P1D')); For some reason it is losing an hour each time that I add a day. I start out at 19:00 and each iteration through the loop adds a day, but loses an hour.
2010-09-19 19:00:00
2010-09-20 18:00:00
2010-09-21 17:00:00

I can correct for this by doing ->add(new DateInterval('P1DT1H'));, but adding 25 hours instead of 24 hours doesn't make any sense to me. I am using PHP Version 5.3.1.

Any ideas?

Thanks,

Hi all,
I am currently storing dates and times for certain events in the following format:

$now= date('Y-m-d H:i:s');

This variable is then stored in a MySQL field of type DATETIME. I am looking for a way to query the database to return all results in a certain month, or within a certain time range, or a certain year etc.

How would this be achieved?

e.g. If I wanted to select everything for the year 2009, would it be:
SELECT * FROM table WHERE date BETWEEN '2009-01-01 00:00:00' AND '2009-12-31 11:59:59' ?

Thanks!

Hi, basically i am parsing some rtf/word files and generating excel csv's for upload into mysql database....my issue is in one of the fields i want to store the value in the mysql datetime / date  format but excel keeps reformating it. Any help on how to overcome this will be highly appreciated.

I am trying to import into a csv file and filter the results to a particular user and only results based on the time the data was uploaded within one hour.  In other words anything not uploaded within the last hour of the start_time will not appear in the csv file.  Everything works fine except for the time part.  I get no results at all with the 'and unix_timestamp........   For all I know possibly I am way off with my effort.  The field name is start_time.  Here is code below.  Appreciate any help.

<code>  header('Content-type: application/csv');
header('Content-Disposition: attachment; filename='.$filename);
$then = time() + 3601;
$query = "SELECT * FROM ppb_listings where user_id = '4' and unix_timestamp(start_date) < $then";
$result = mysqli_query($conn, $query);
while($row = mysqli_fetch_row($result)) {
    fputcsv($fp, $row);
}
echo $result;
exit;

</code>

It is my belief that when storing time in the DB, it should always be at UTC.  Agree?  My question is whether one should work with DateTimes with a specific time zone or only do so when displaying the time to the user?

For example, if I have multiple users which have a timezone string property based on their physical location as well as a datatime property when some event occurred for the given user, and need to implement some logic if the event occurred more than a given duration from the current time, which of the following approaches should be used?

$currentTime = new DateTimeImmutable();
$userEventTime = new DateTime($queryResults['theEventField']);
if($currentTime->sub(new DateInterval('P10D')) < $userEventTime) {
    //Display time to the user
    $displayEventTime = new DateTime('@'.$userEventTime->getTimestamp(), new DateTimeZone($queryResults['userTimeZone']))->format('Y-m-d H:i:sP');
}

 

$currentTime = new DateTimeImmutable('now', new DateTimeZone($queryResults['userTimeZone']));
$userEventTime = new DateTime($queryResults['theEventField'], new DateTimeZone($queryResults['userTimeZone']));
if($currentTime->sub(new DateInterval('P10D')) < $userEventTime) {
    //Display time to the user
    $displayEventTime = $userEventTime->format('Y-m-d H:i:sP');
}
