Romain - you were so right.  A little less calculating to be done and I 
got the result I wished.  For anyone interested here's the function I'm 
using to determine how much time there is until a cookie expires.  The 
cookie in question contains the expiration datetime that was used to 
create a paired cookie.


function GetTimeLeft($applid)
{
   if (isset($_COOKIE[$applid]))
   {
  if (isset($_COOKIE[$applid."expire"]))
  {
 $curr_time = new datetime();
 $cookietime = $_COOKIE[$applid."expire"];
 $exp_time = new datetime();
 $exp_time->setTimeStamp($cookietime);
 $diff = $curr_time->diff($exp_time);
 $days = $diff->format("%d");
 $days = ($days > 1) ? "$days days": ($days == 1) ?
   "$days day" : '';
 $hms = $diff->format("%h:%i:%s");
 return "Time left: $days $hms";
  }
  else
 return '?';
   }
   else
  return '0';
}

Good Point!  I never looked at it that way.  I guess the Date function 
can't be relied on in that case.  So now I'll have to calculate my time 
in a mathematical way instead of letting Date translate it for me.

Aziz, please try not to top post :)

It's true that the date() function takes in a timestamp as its argument,
but a timestamp is a number representing the number of seconds since
00:00:00 1st January 1970, so passing in a very small number of seconds
is perfectly valid.

The only thing that would account for the 7 hours difference is the time
zone, which would also be part of the timestamp.
http://en.wikipedia.org/wiki/Unix_time gives more details.

The resulting subtraction is not a valid timestamp, but rather the
difference between the two timestamps in seconds . The resulting diff can
be 1 if the timestamps are 1 seconds apart. The

Look at my code. The inputs are all timestamps so date should work, no?
My question why am i getting an hour value in this case?

Re: [PHP] date time problem

[Aziz Saleh]

Jim,

The date method takes in a timestamp (not seconds away).

You have the seconds, you will need to manually convert those seconds to
what you desire (minutes = seconds / 60), (hours = minutes / 60), etc..

I have this:

Currently the results are:

curr_time is 06:12:03
the diff is 2584
All of these are correct.

BUT time_left is 07:43:04 when it should be only "00:43:04".

Thanks for the quick response, but why do I want to show the time in GMT?  However, I did 
try it, changing the 'time_left' calc to use "gmdate".  Now instead of a 7 for 
hours I have a 12.

I've upgraded to 5.3.3, got rid of the external Date extension and
implement your solution. It's working perfectly. Thanks much!

The extension is this:
http://pear.php.net/package/Date/docs/latest/Date/Date.html - but that
is also a very old version. I am working on getting the upgrade done.

I found this function a while back when I was converting UTC to EST... simple 
task I know, but still...

( I am sorry to whomever wrote this, I didn't keep the source where I found it )

function convert_time_zone($date_time, $from_tz = 'UTC', $to_tz = 
'America/Toronto')
{
 $time_object = new DateTime($date_time, new DateTimeZone($from_tz));
 $time_object->setTimezone(new DateTimeZone($to_tz));
 return $time_object->format('Y-m-d H:i:s');
}


I don't seem to have the DateTime object. We are running 5.1.6 and
that was added in 5.2.0. We are getting the Date module from an
external extension. I'll have to see about upgrading.

Well, if you're getting the Date class from a custom extension, then we 
can't help you. Simply because we have no clue what the extension's code 
is.


Also, please ask your host to upgrade, 5.1.6 is hopelessly outdated (and 
unsupported!). The current version is 5.4 with 5.5 coming out very very 
soon.

I found this function a while back when I was converting UTC to EST... simple 
task I know, but still...

( I am sorry to whomever wrote this, I didn't keep the source where I found it )

function convert_time_zone($date_time, $from_tz = 'UTC', $to_tz = 
'America/Toronto')
{
$time_object = new DateTime($date_time, new DateTimeZone($from_tz));
$time_object->setTimezone(new DateTimeZone($to_tz));
return $time_object->format('Y-m-d H:i:s');
}

Maybe this can help you?

You might want to put quotes around that value so it is actually a 
string and does not get evaluated.

Marc,

When you take a date and do a strtotime you are converting it to an int which 
you can compare to each other much easier. So for your above example you would 
be best doing.


define('WSOFFBEGIN','09/16/2012');
$jes = 01/03/2012;

if ( strtotime($jes) < strtotime(WSOFFBEGIN) )
{
 $error = " MUST begin after " . WSOFFBEGIN . "\n";

I cannot figure out why the $error is being assigned inside the if statement,

And hopefully put quotes around 01/03/2012.

You shouldn't be comparing the date strings, but the UNIX timestamp values:

define('WSOFFBEGIN','09/16/2012');
$jes = 01/03/2012;

if ( strtotime($jes) < strtotime(WSOFFBEGIN) )
{
$error = " MUST begin after " . WSOFFBEGIN . "\n";
}

Won't this give you the same results without the extra conversion steps?

$todaydate = date("U");
$showenddate = strtotime($showsRecord['end_date']);



if ($todaydate<  $showenddate):

The problem that I am encountering is that PHP is rendering the reverse of

If today's date is *11 Nov 2012* and the show's end date is *18 Nov 2012*,
the message that I am getting is *the show has ended* which is wrong. A

Try this:

$todaydate = strtotime(date("D, M jS, Y g:i:s a"));
$showenddate = strtotime(date("D, M jS, Y g:i:s a",
strtotime($showsRecord['end_date'])));

if ($todaydate < $showenddate):
echo "The date of the show has not yet arrived";
else:
echo "The show has ended";
endif;

In that case the code you're showing us is not the code you're running, because 
that's the obvious error in test.php.

Stuart,

I reversed it as you suggested and every future show is displaying as
having ended.

This is what you have:

if ($todaydate > $showenddate): 
echo "The date of the show has not yet arrived"; 
else:  
echo "The show has ended"; 
endif; 

That says: if the current time is later than the end date of the show, tell 
them the date of the show hasn't arrived yet.

What you mean is: if the current time is later than the end of the show, tell 
them the show has ended.

if ($todaydate < $showenddate): 
echo "The date of the show has not yet arrived"; 
else:  
echo "The show has ended"; 
endif; 

It's a simple logic error.

Your comparison is backwards:

if ($todaydate > $showenddate):

should be

if ($todaydate < $showenddate):

Hi Shiplu and Stuart,

Comparing timestamps was my first option. I've reinstated it. Have a look
at http://www.lakesidesurrey.co.uk/test.php (show_source included) and you
will see that PHP is still outputting the wrong thing.

I just can't figure out what's wrong.

The date function returns a string.

So here you are comparing two strings; PHP has no idea they are dates.

Compare timestamps instead, i.e. time() for the current time, and what you get 
back from strtotime for the end date.

[shiplu]

You can always use timestamp which is integer.

$todaydate = time();
$showenddate = strtotime($showsRecord['end_date']);

Haluk,

After you retrieve the date from the database you still have to convert it
from a string to time and then to a date. Try:

I think you need to double check your variable names.  In one place you 
are using $row['PDate'] in another you are referring to $row['date']

Have you enabled all warnings in PHP, and checked the Apache error log
after that? It probably contains a hint on why it doesn't work...

This definitly looks like a timezone offset!
Try the following code in your environments.

$date  = new  DateTime ( );
$tz  =  $date -> getTimezone ();
echo  $tz -> getName ();


PHP for CLI mode has a different php.ini than the one for apache2. Maybe
that is a problem?

Check also


php -i | grep "date.timezone"

Simon,

I was dumping out the value from ini_get('date.timezone'); seems it must be
getting set at runtime.

A call to date_default_timezone_set() during execution can change the timezone. 
If you add echo date_default_timezone_get(); just before this, does it give the 
same output as your date.timezone setting?

Did you set the timezone? If not, PHP raises a notice, which causes
terrible performance (see the comment at the bottom):

Re: [PHP] date problem

[Dan Dan]

It seems different php versions have different outputs for this code:

Fedora Core 14 (x86):

first: 01-03-2011 00:00:00
second: 08-03-2011 00:00:00
third: 22-03-2011 00:00:00
fourth: 22-03-2011 00:00:00
fifth: 29-03-2011 00:00:00

Fedora Core11 (x86_64):

first: 31-12-1969 16:00:00
second: 31-12-1969 16:00:00
third: 22-03-2011 00:00:00
fourth: 31-12-1969 16:00:00
fifth: 31-12-1969 16:00:00

However it works if reorder Year and Month like:

echo "first: ".date("d-m-Y H:i:s",strtotime('2011 March first
wednesday'))."\n";
echo "second: ".date("d-m-Y H:i:s",strtotime('2011 March second
wednesday'))."\n";
echo "third: ".date("d-m-Y H:i:s",strtotime('2011 March third
wednesday'))."\n";
echo "fourth: ".date("d-m-Y H:i:s",strtotime('2011 March fourth
wednesday'))."\n";
echo "fifth: ".date("d-m-Y H:i:s",strtotime('2011 March fifth
wednesday'))."\n";

first: 02-03-2011 00:00:00
second: 09-03-2011 00:00:00
third: 16-03-2011 00:00:00
fourth: 23-03-2011 00:00:00

Just try "of March". Worked for me.


print "first: ".date("d-m-Y H:i:s",strtotime('first Tuesday of March
2011'))."\n";
print "second: ".date("d-m-Y H:i:s",strtotime('second Tuesday of March
2011'))."\n";
print "third: ".date("d-m-Y H:i:s",strtotime('third Tuesday of March
2011'))."\n";
print "fourth: ".date("d-m-Y H:i:s",strtotime('fourth Tuesday of March
2011'))."\n";
print "fifth: ".date("d-m-Y H:i:s",strtotime('fifth Tuesday of March
2011'))."\n";

Re: [PHP] date problem

I removed the day (1 before the March), but its still giving the same
result, i.e. different days of month with and without the 'first'. Any
further help ?

print "first Tuesday :".date("d-m-Y H:i:s",strtotime('March 2011
Tuesday'))."\n";
print "first: ".date("d-m-Y H:i:s",strtotime('March 2011 first
Tuesday'))."\n";
print "second: ".date("d-m-Y H:i:s",strtotime('March 2011 second
Tuesday'))."\n";
print "third: ".date("d-m-Y H:i:s",strtotime('March 2011 third
Tuesday'))."\n";
print "fourth: ".date("d-m-Y H:i:s",strtotime('March 2011 fourth
Tuesday'))."\n";

first Tuesday :01-03-2011 00:00:00
first: 08-03-2011 00:00:00
second: 15-03-2011 00:00:00

Because you're combining the date with the day of the week.  It so
happens that 1 March was a Tuesday, but today - 1 April - is a Friday.
 Pick one or the other, not both.

Have you tried echo'ing out the queries to see if they actually look  
well-formed? One place it could fall over is if the values you're  
using in it aren't well formed.


Lastly, you're using a $_POST field directly in your query if the  
first tertiary if/else fails. You should at the very least validate  
it to make sure it's in the form you expect, which has to at least  
be something that can be parsed and processed by strtotime() which  
you're using in your example.

RE: [PHP] Date Conversion Problem

[David Stoltz]

No Problem Shreyas,

 

My original PHP code was writing the date like this:

echo date('l jS \of F Y h:i:s A'); //  - Thursday 17th of June 2010
08:58:02 AM

 

I changed it to this:

echo date('n\/j\/Y h:i:s A');//   - 6/17/2010 08:58:02 AM

 

Now that it was writing to the database correctly, I ran the following
script below to update all the rows that were improperly formatted.
After the below script ran, I didn't even have to convert the column to
datetime, since the SQL convert statement would now easily convert the
string to date - although the proper thing to do would be to convert the
column to date/time type. 

 

The below script was written in classic ASP- I've added a commented out
string below each step so you can see the changes being made to the
string:

 

<%

'This script was used to convert invalid php dates into true date
formats in the DB

 

set conn = Server.CreateObject("ADODB.Connection")

conn.open = "My DB Conncetion String"

 

set rs = conn.execute("SELECT id, employee_signed_on FROM TABLE1 WHERE
employee_signed_on is not null")

 

do while not rs.eof

 

id = rs("id")

temp = rs("employee_signed_on")

oldDate = rs("employee_signed_on")

'''''''''''''''''''''''''''''''''''''Thursday 17th of
June 2010 08:58:02 AM

 

oldDate = replace(oldDate,"Monday ","")

oldDate = replace(oldDate,"Tuesday ","")

oldDate = replace(oldDate,"Wednesday ","")

oldDate = replace(oldDate,"Thursday ","")

oldDate = replace(oldDate,"Friday ","")

oldDate = replace(oldDate,"Saturday ","")

oldDate = replace(oldDate,"Sunday ","")

oldDate = replace(oldDate,"rd of ","/")

oldDate = replace(oldDate,"January ","1/")

oldDate = replace(oldDate,"February ","2/")

oldDate = replace(oldDate,"December ","12/")

datetemp = split(oldDate,"/")

newMonth = datetemp(1)

newDay = datetemp(0)

theNewDate = newMonth & "/" & newDay & "/" & stuff

Re: [PHP] Date Conversion Problem

[Shreyas Agasthya]

David,

I think it would help people like me (newbie) to know the exact statements.
Though I could envisage what you would have done with my current learning,
it would be good if I double check the statements that went there to fix
it.

Shreyas

RE: [PHP] Date Conversion Problem

[David Stoltz]

Thanks all - I've fixed the problem.

I fixed it by updating the php statement to write the date in a true SQL 
date-ready format. Then I updated the invalid rows.

Thanks all!

The "fix" is most likely to be ...

1 - Convert the string date using PHP's strtotime() function to
populate a new column on the DB.
2 - Find the code that inserts/updates the date string and add the new
column to the insert/update statement.

That will preserve the current app and allow you to have the new
column for new work.

Just remember, if _YOU_ update the new column, you must also update
the original date string also.

RE: [PHP] Date Conversion Problem

[David Stoltz]

Here's my approach to this problem, and how I am planning on fixing this - tell 
me what you think if this will work...

I need the format in the database to be "1/14/2010 3:25:58 PM"

There's not a ton of records that need to be updated, so I was going to:

1) Change the PHP function that is writing the date format incorrectly to the 
above format
2) Then manually go through the records and update the incorrect dates
3) Then change the datatype in the DB for that column from varchar to datetime

Far as I can see, this should work. 

This is why I hate inheriting other people's stuff...not to mention I'm a 
newbie, so that doesn't help ;-)

Thanks!

Having said that, you will have some serious issues is your dates are
generated from around the world and not purely in your local timezone.

A lack of timezone (Europe/London, Europe/Berlin) rather than the
timezone offset (+1:00, etc.) is the issue here.

Due to DST changes not being consistent worldwide, with the timezones
changing over time, etc. All quite complicated.

Under normal conditions, you would store the date in a datetime
column. That allows you to do all the date range work in the DB.

When you display the date, you would use PHP's date() function for
format it appropriately.


date('l jS \of F Y h:i:s A', $row['fieldname']);

sort of thing.

I would agree with you, but I have no control on inherited web apps.

 

I now need to concentrate on trying to fix this.

It's best to store the date as a date rather than a string, as it avoids the 
sorts of problems you're seeing now.

Something like select timestampdiff(month, '2010-01-01', '2010-05-22');
should work.

$from = getdate($udate1);
$from_year = $from['year'];
$from_month = $from['month'];

$to = getdate($udate2);
$to_year = $to['year'];
$to_month = $to['month'];

$months = $base_months + $add_months;
}
else { // $to_month < $from_month
$num_years = $to_year - $from_year;
$base_months = $num_years * 12;
$sub_months = $from_month - $to_month;
$months = $base_months - $sub_months;
}

This will give the months between two dates, ignoring the actual day of
the month for each date (may not be exactly what you want, and code is
untested).

My code above is submitted because I don't like doing calculations with
seconds. Tedd's right, the OP's questions can't be answered precisely
because months vary in number of days.

And not taking the time to research your question before posting is 
what, thoughtful and kind?


The phrase RTFM is something I don't like to tell people, and from 
what I remember, I have never said that to anyone. However I can 
understand where one could read a person's question and deduce that 
they did NO research for themselves. Instead, they posted their 
question for others to do their research for them because they were 
too lazy to do it themselves. No matter how you cut that, that's 
lame. So, I certainly don't blame anyone for telling such a person to 
RTFM.



 I would suggest
that when a question asked here causes you to respond with RTFM, don't
respond at all. Save yourself the time and trouble and save the person
asking the question the grief of being insulted.


Well that's your prerogative to do as you want. But it's a bit 
arrogant of you to tell others how to conduct themselves on this 
list, don't you think? Who made you list monitor?




And Tedd your condescending
response caused me to lose respect for you.


No offense, but let me make this perfectly clear -- I don't give a 
rat's ass what you think about me. From my perspective, you could win 
the lottery or die tomorrow, it makes no difference to me either way.


I'm not here to win/lose your respect. I'm here to help those who ask 
honest questions. I, like many others, simply donate our time freely 
without any benefit whatsoever. If you have problems with that, then 
you probably have bigger problems elsewhere.




I'm sure the OP would have been
more than thankful to receive the same response without the RTFM. I'll read
any response to this, but I won't have anything more to say. This list has
been polluted enough lately with nonsense. Incredible.


What's Incredible is how people can post to this list thinking that 
they have some right to post whatever they want and expect others to 
comment as they want. And, if they don't get what they want, then 
they whine about the list being rude and mean. That's Incredible.


My advice, if you have problems with this list, get over it! There's 
much more in this world to get upset about rather than what happens 
on this list.

I can't argue with this approach. If you're going to point the poster to
the manual and *then* explain, that's the ideal way to do this. Now it
could be argued that you could say, "Please refer to
http://php.net/manual/en/whatever.php for more info." Or you could say,
"RTFM". The former is more polite, but the latter will suffice. Both
mean the same thing; one is simply more terse.

Also stipulated that one should research a question as much as possible
before posting to this list. We're not tutors; more like professional
side-checkers.

(Please don't take this the wrong way, newbies. You're welcome to ask
questions here. Just do whatever research you can first, and follow our
advice afterward, to RTFM.)

You're entitled to your opinion as much as I am, and my opinion is
that not making it clear to people that the answer to their question
is plainly obvious in the manual is just as rude if not more so than
suggesting they RTFM.

I make a point to never just say RTFM but to also answer the question
at the same time, but IMHO not telling people how fundamental their
question was does not help them in the long run. At the end of the day
it just encourages them to continue to rely on this list rather than

I make no apology for my attitude towards this type of question, and

 Arrggg.

 But good to know.


And if you absolutely insist on doing it this way, make sure you 
start in the middle of the day -- if your base time is 12:00 noon 
(which is what I always use in this situation), the furthest it can 
go because of DST is 11:00 or 13:00, which won't screw you up if all 
you're interested in is the date. ;)

This and the "2038" bug are reasons to do this type of calculation with
Julian days, as opposed to seconds.

No. Due to Daylight Saving Time, many time zones have two days each

You got it.

Just transform any date to seconds and then compare those seconds to 
other seconds (taken from other dates) and evaluate. Dead simple.


Also note that the strtotime() and date() combination provides some 
very nice features like keeping track of the resultant date. You 
don't have to worry about leap years, or months having 28-31 days, or 
anything like that -- it's all taken care of for you, pretty neat huh?

PHP (like all languages I know) treats dates as numbers; and PHP
specifically uses seconds since January 1st 1970 (other languages
sometimes have different start points and can measure in milliseconds
instead). With this in mind, you can compare dates directly as you would
an integer, and the later date will be the higher value.

To add 30 days to a given date, you could use the date_add function
(http://uk2.php.net/manual/en/datetime.add.php ) which has various
formats you can use to add different time units.

Lastly, to turn a date like 8/26/2009, I would probably try to break it
down into it's component parts (maybe using explode('/', $string_date) )
and then using those values as arguments in a mktime() function. PHP
should automatically treat the values as integers if they are strings,
because like ASP, it uses loose typing on variables.

David :

First get the date to seconds, like so:

$today_date = '8/26/2009';

$next_date = strtotime($today_date) + (86400 * 30);

OR

$next_date  = strtotime('+30 days', strtotime($today_date));

Then take the seconds back to a date, like so:

$the_date = date('m/d/Y', $next_date);

Here's the example:

[kranthi]

i prefer http://in3.php.net/strtotime it supports loads of other
formats as well (including +30 days and 8/26/2009)
above all it returns unix time stamp which can be used directly with date().

David,

Look up date() and mktime() in the manual.

To get today's date is easy: date('m/d/Y');

But when wanting to add days/months/years to a date, you need to use
mktime()

mktime() breaks apart a date into hours/minutes/seconds/months/days/years.

Therefore I always break up my date into these types fo sections.

$month = date('m');
$day = date('d');
$year = date('Y');

Now that I have them seperated I create a variable $future_date and assign
it the value I want. In your case, 30 days in the future.

$future_date = mktime(0,0,0,date($month),date($day)+30,date($year));

Now I put it back into a date format.

$future_date = date('m/d/Y',$future_date);

echo $future_date;

Today is September 1st and the value of $future_date is October 1st because
there are 30 days in Spetember.

Now you can compare your dates.

if ($nexteval > $future_date) {
  echo "This date has already passed";
} else {
  *do some processing*
}

Hope that helps.

Dan

RTFM.

The strtotime function will give you a timestamp, getdate will give
you an array, so your comparison is non-sensical. Use the time
function to get the current date/time as a timestamp.

David:

Try to understand what strtotime() does and you'll get your answer.

Function returns the number of seconds from January 1, 1970 to the 
date you enter. If the number of seconds are less than the current 
date, then the entry is past.


Understand?

You need to read the strtotime page in the manual.

http://php.net/strtotime

It says that the second argument of the strtotime function is suppose to be a 
unix time stamp.

Is the value that you gave us for $date_reference a unix time stamp?  No

Your code should be like this.

// This converts 2009-04-19 00:00:00 into 1240099200
$date_reference_unix = strtotime($date_reference);
$previous_date = strtotime("-1 days", $date_reference_unix);
$previous_date = date('Y-m-d', $previous_date);

echo $previous_date;   outputs 1969-12-30

That's what I'm talking about. Those functions like javascript's
getMonth() return an int that is one less than the month number. My
assumption is that people who defined the language made it this way so
that you can write code that uses non-associative, zero-based arrays
to decode the month number to a string:

var month_names['en'] = new Array('January', 'February', 'March',
'April', 'May', 'June', 'July', 'August', 'September', 'October',
'November', 'December');
var myDate = new Date();
var x = month_names['en'][myDate.getMonth()];


If getMonth() wasn't zero-based, you'd either have to include an empty
element in the 0th position of at the beginning of the array, use an
associative array, or that last line would have to be changed:

var x = month_name['en'][myDate.getMonth() - 1]'

It just flew in the face of all I knew at the time to have a

I suspect it was done because it allows people to work with arrays for
month names (including the options array that is part of the
Javascript objects that represent SELECT tags) without having to
subtract one from the index each time it gets used. In that sense, I
can see the reasoning of why months and days of the week work that way
(even though I think it's counter-intuitive and subtraction is a
pretty simple operation).

I don't understand why the day of the month or of the year would be
zero-based, though. It's almost like the function just takes the
number of seconds elapsed since the beginning of the year, divides by
86400 and truncates the result to a integer.

I dunno. Threw me for a hell of a loop (no pun intended) when I first started 
playing with Javascript dates, though. Year = starts at 1 (not literally, but 
for all intents and purposes). Day = starts at 1. Month = starts at 0? What?! :)

Hmm, though I know us programmers love to start counting at zero, why 
would something as static as a date start counting at zero? I would have 
imagined something like that would start at 1.


Guess it's just me.

$smont = 10;
$sday = 13;
$syear = 2008;
$timestamp = mktime(0,0,0,$smont,$sday,$syear);
$thismonth = getdate($timestamp);

Here is where the problem comes into play.

echo $thismonth['yday'];

This displays 286 when in fact its 287.
Is there a problem in my ini file or what is the deal.


Are you sure this isn't like Javascript's "getMonth" function? Its index may begin at 0, making 
"day 0" the "first day" of the year.

(it is a leap year)
