I'm working with Laravel 5.8 and I wanted to show a popup message if the UNIX timestamp of the current date is equal to the defined Unix timestamp of the popup.
So in order to do that, I added this at the Controller:
$date1= $popup->datep; // returns 1636403400
$date1 = Carbon::createFromFormat('Y-m-d H:i:s', $date1);
dd($date1);
But instead of getting the result of $date1, I get this error:
The separation symbol could not be found Data missing
So what's going wrong here? How can I solve this issue?
You are specifying a format that is clearly not an unix timestamp. Use method for the timestamp.
$date = Carbon::createFromTimestamp($popup->datep);
If you want to compare it to be the same date, you should do the following. I don't assume you want to compare it by the hour or second, that those will almost never match.
$date->startOfDay()->eq(now()->startOfDay());
Regarding Carbon Docs:
createFromFormat() is mostly a wrapper for the base php function DateTime::createFromFormat.
which is means that your second parameter must be a valid date/time format, not a timestamp.
The DateTime::create docs:
$datetime
String representing the time.
Instead, you need to use the createFromTimestamp instantiator.
$date1 = Carbon::createFromTimestamp($date1);

In my controller, when I create an event, it saves perfectly fine. The user enters a date in dd-mm-yyyy and it gets saved in MySQL DATETIME format. Then the details view renders it completely fine, just like the edit view via model binding.
As soon as I try to save from the edit form, the date somehow fails and returns 1970-01-01 00:00:00.
I am not really sure why this only happens on my update method, as my store method is in essence the same.
$input = Input::all();
$input['plannedTime'] = date('Y-m-d H:i:s', strtotime(Input::get('plannedTime')));
How comes the update method returns no error, validation is alright, but it still won't save it correctly?
The value of 'plannedTime' is a string of date format d-m-Y H:i:s.
There's your problem. PHP's strtotime does its best, but 04-05-2015 00:00:00 could be either April 5 or May 4, depending where you live.
As an example, on my install, strtotime('04-13-2014 00:00:00') fails (which'll get converted to 0, which'll get converted to 1970-01-01).
Laravel's date validation expects a value that strtotime can handle. If you're using an ambiguous date format, use createFromFormat to parse it, then format to spit it out in a more standard format.
$date = DateTime::createFromFormat('d-m-Y H:i:s', Input::get('plannedTime'));
$usableDate = $date->format('Y-m-d H:i:s');
MySQL never returns any error for invalid dates as far as i can remember, it just sets it to EPOCH and thats it!
You should enforce your dates to be always converted to a "Y-m-d H:i:s" format when communicating with your site and display the date in "d-m-Y" only on the output side.
You should try and use
public static DateTime DateTime::createFromFormat ( string $format , string $time [, DateTimeZone $timezone ] )
To create a datetime object from a format. If you know your format such as in this case, then provide the format and get a date object back which will be persisted correctly!
In my PHP script I've got a function handling birthdays like so:
$dateTime = \DateTime::createFromFormat('U', $time);
The problem is that this returns false with negative $time numbers (i.e. dates before 1-1-1970). In the PHP docs there's a comment saying that indeed
Note that the U option does not support negative timestamps (before
1970). You have to use date for that.
I'm unsure of how to use Date to get the same result as DateTime::createFromFormat() gives though. Does anybody have a tip on how to do this?
If you just need to format a UNIX timestamp as a readable date, date is simple to use:
// make sure to date_default_timezome_set() the timezone you want to format it in
echo date('Y-m-d H:i:s', -12345);
If you want to create a DateTime instance from a negative UNIX timestamp, you can use this form of the regular constructor:
$datetime = new DateTime('#-12345');
I am new to PHP and I am trying to learn more of php date and time but I seem to get stuck with this.
I have this date format:
ddMMyyHHmmss
And an example is 120813125055 but I am trying to manipulate the string such that it will give me the format of:
yyyy-MM-dd HH:mm:ss (in the example above, 2013-08-12 12:50:55)
I tried to do something like:
date('Y-m-d H:i:s', strtotime('120813125055'));
But it always gives me a result of 1969-12-31 18:00:00.
I assume that I need to do some string manipulation in PHP for this but I was wondering if there is an easier and more efficient way to do it?
I think what you're looking for is in the second response answered here: how to re-format datetime string in php?
To summarize (and apply to your example), you could modify the code like this.
$datetime = "120813125055";
$d = DateTime::createFromFormat("dmyHis", $datetime);
echo $d->format("Y-m-d H:i:s");
Use date_create_from_format:
$ts = date_create_from_format('dmyHis', '120813125055');
$str = date('Y-m-d H:i:s', $ts);
strtotime() only works on EASILY recognizable formats. Your is a ugly mix of garbage, so no surprise that strtotime bails with a boolean FALSE for failure, which then gets typecast to an int 0 when you tried feed it back into date().
And of course, note that your time string is NOT y2k compliant. two digit years should never ever be used anymore, except for display purposes.
You're using your function call and the argument the wrong way around.
In your example, php will try to return you the date for which the time is 'strtotime('120813125055')', and this function returns false (interpreted as 0). So you get returned the date formatted in 'Y-m-d H:i:s' for the Unix epoch.
You will need to get the actual timestamp of your string, so use http://www.php.net/manual/en/datetime.createfromformat.php.
You are mistaken here..
I tried to do something like:
date('Y-m-d H:i:s', strtotime('120813125055'));
You shouldn't use only numbers ( doesnt matter its an integer or a string ), than it will always give you the same thing.
You can use any other valid date and time ( E.G. 6 Jun 2013, 5 may 12...) . Because what strtotime() do is detect a valid date and convert it into timestamp.
The values that I received from my device are: 090211 = ddmmyy and 062123 = hhmmss in UTC.
But I found that the time is always 8 hours later if compared to the time that I need. It is because the time for Malaysia is +8:00. First I would like to add 8 hour, and finally I would like to store this kind of date format into my MySQL database as "2011-02-09 06:21:23". How would I convert these values?
To convert in PHP to a datetime, you will need the function DateTime::createFromFormat(); This function will return a DateTime.
Using this function you can also pass the timezone as a parameter.
Example:
$date = DateTime::createFromFormat( 'dmy Gms', '090211 062123', new DateTimeZone("Europe/Amsterdam") );
You can create a output a following:
echo $date->format('Y-m-d H:i:s');
or UNIX timestamp for the MySQL:
echo $date->format('U');
Hope this helps!
PHP has both localtime and gettimeofday functions, are you by chance using the wrong one (or misinterpreting its results)?
To change 2009-12-09 13:32:15 to 09/12/2009
here:
echo date("d/m/Y", strtotime('2009-12-09 13:32:15'))
You can use strtotime to get the timestamp of the first date, and date to convert it to a string using the format you want.
$timestamp = strtotime('2009-12-09 13:32:15');
echo date('d/m/Y', $timestamp);
And you'll get :
09/12/2009
[edit 2012-05-19] Note that strtotime() suffers a couple of possibly important limitations:
The format of the date must be YYYY-MM-DD; it might work in some other cases, but not always !
Also, working with UNIX Timestamps, as done with date() and strtotime() means you'll only be able to work with dates between 1970 and 2038 (possibly a wider range, depending on your system -- but not and illimited one anyway)
Working with the DateTime class is often a far better alternative:
You can use either DateTime::__construct() or DateTime::createFromFormat() to create a DateTime object -- the second one is only available with PHP >= 5.3, but allows you to specify the date's format, which can prove useful,
And you can use the DateTime::format() method to convert that object to any date format you might want to work with.
Using the date() method.
print date("d/m/Y", strtotime("2009-12-09 13:32:15"));
$long_date = '2009-12-09 13:32:15';
$epoch_date = strtotime($long_date);
$short_date = date('m/d/Y', $epoch_date);
The above is not the shortest way of doing it, but having the long date as an epoch timestamp ensures that you can reuse the original long date to get other date format outputs, like if you wanted to go back and have just the time somewhere else.
