Re: [PHP] Date question
I have a datetime column in MySQL DB. How can I match to that column from
php code if I only have the date information available.
2006-02-24 12:00:00 against2006-02-24
This might be more SQL question sorry about that.
use date_format(%Y-%m-%d,'date_column') in the sql
http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html
The above is likely one of the more elegant solutions. But if you wanted to
do this
completely in PHP, you could do something like:
pseudocode
$phpDate = '2006-02-24';
$rowData = mysql_fetch_assoc( $yourQuery );
if( date( 'Y-m-d', strtotime( $rowData['MySQLDate'] )) == $phpDate )) {
echo 'Dates match!';
}
/pseudocode
thnx,
Chris

[PHP] date(H, $datevalue) always adds an hour?
Hi All, Wondering if anyone can help me work out why date(H) always adds an hour? I'm *assuming* it thinks it should be compensating for Daylight Saving Time (though I'd be just as willing to believe that it's caused by something else), however we don't observe DST in Queensland, Australia. Making matters a little more complex, while my local machine shouldn't be compensating for DST (if that's what's happening), my remote machine (based in Florida somewhere, I think) should, when applicable. So, just to explain a little better. Let's say the clock on my computer reads 7:00pm. If I do echo date(H); it will output 20, instead of 19. The same thing happens if I take a date value from my mysql database. $sql = SELECT UNIX_TIMESTAMP(datecreated) AS unx_date FROM mytable; $rs = mysql_query($sql); $row = mysql_fetch_object($rs); echo date(H, $row-unx_date); If the above record contained the value '2006-01-10 19:00', the code would output 20 instead of 19. Can anyone help me figure out how to accommodate for this? Much warmth, Murray -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Not only does it depend on the machine's location, and where the machine thinks it's located (you could lie to your computer, you know) but also the 'locale' settings and the BIOS UTC setting, and the server's settings in the OS and/or NTP client and... Oh, plus with MySQL, there are settings that can convince MySQL to not pay attention to the OS about its locale/zone settings and to do someting else instead. Tracking down where the fault lies is generally not fun But at least now you know where to look :-) I usually throw my hands up in despair and just add/subtract whatever, and then check it again when daylight savings changes over and see if it still works -- Because I have zero control over any of the settings on a shared server anyway.

Not sure if this will help, but:
# Set time zone:
putenv('TZ=US/Pacific'); // I am on west-coast, my servers are on east,
if not for this code the timestamp used in my script will reley upon
the server time. This line of code will over-ride server time.
Maybe look-up putenv on php.net and read-up in the comments section, I
usually find good info that way.

[PHP] date processing needed in form
Hello - I need to create a form that allows the user to select a Month, Day and Year. I am also new to PHP and am wondering if there is a way for me to display the contents of the Select list box (for the Day) based on the Month that is selected (and Year), so that the valid number of days for the month ( year?) displays. For all of our other forms, we use CGI to handle our standard forms validation, and was hoping to handle more complex validation within PHP prior to sending the entire contents of my form to our standard CGI validation routine. I know that I could use the Checkdate function once the entire date is selected, but thought there might be an easier/more efficient way of handling this and also not sure how to reference Checkdate prior to Submitting my form to the CGI routine. I also was not sure if this was something that is handled easier using Javascript? Any help/examples, etc. would be greatly appreciated! Thanks!!

Since PHP is server-side, a more elegant solution could be achieved using javascript. In order to do this with PHP, your script would have to make the trip back to the server after the month was entered to calculate the valid day.

[PHP] date comparisions...
I am confused... probably because of lack of sleep.
Anyway... I have code that looks like this:
if ($discountResult[dateexpired] date(U))
{
//dosomething
}
else
{
//do something else
}
Using Epoch obviously
Anyway... it's supposed to read: IF the expired date is past the current
date... disallow dosomething otherwise... let it go.
I set the expire date to be Sept 30, 2005 and obviously today is the
current date but for some reason the dosomething is being allowed.
Do I have the operators mixed up here? Works is I reverse the operator but
shouldn't it work as I have it?
Thanks all. Appreciate the clarrification.

Start with the obvious - what actually IS the value of
$discountResult[dateexpired]? var_dump it out and have a look. Check
you are comparing like with like. You're also not performing a strict
comparison, so string conversion could be going on here.
The other obvious fact is that if dateexpired is less than *right

Re: [PHP] date comparisions...
Hi Rich, Thanks for your reply. dateexpired is: 1128052800 which translates into: 2005-09-30 00:00:00 Basically, I'm just trying to figure out when the dateexpired is. IF it is past the current date then I am erroring out and if it's under the current date... I'm allowing the transaction. I would assume the following: if (2005-09-30 00:00:00 2005-10-07 00:00:00) it should error out, no? Thanks!

For instance, if you want to increment a date in a MySQL table, you would likely do it with a MySQL statement, because to do it in PHP, you need to do a read, then add the day, then a write, (two DB calls). With MySQL, you would just do something like: update `mytable` set 'columnname` date_add(columnname, interval 1 day); One call to the DB instead of two, much more efficient. There are many instances where you would want to use PHP to manipulate dates too, depending on their circumstances.

Re: [PHP] mysql/php date functions..
Read up on mysql date types and functions. You can convert a unix timestamp to a mysql date with the FROM_UNIXTIME() function. If you want to store as unix timestamp, store it in an int field. To use mysql date functions on it, use the FROM_UNIXTIME() function. If you want to store dates in mysql timestamp fields, use in a select statement a) UNIX_TIMESTAMP() or b) DATE_FORMAT() to a) convert to unix timestamp and process with PHP or b) format date for output. http://dev.mysql.com/doc/mysql/en/date-and-time-types.html http://dev.mysql.com/doc/mysql/en/date-and-time-functions.html kgt bruce wrote: or.. better yet. if i do a php - time(), i get a unix_timestamp var. how do you guys store this in mysql. you can't simply do an insert into a mysql/timestamp var. so how do you convert it? also, once you have the mysql tbl, how do you go from the mysql timestamp var - the php var? thanks bruce -Original Message- From: bruce [mailto:[EMAIL PROTECTED] Sent: Monday, September 26, 2005 12:38 PM To: 'John Nichel'; php-general@lists.php.net Subject: RE: [PHP] mysql/php date functions.. so you play with the time/date vars on the php side, and then simply store them in the mysql tbl as a int(10)... or do you actually store the vars in the mysql timestamp... and then use the mysql date/time functions... ie. how would you do the following... get a date (date1) get a date (date2) store the date1/time in mysql add the date1 + date2 and store the result in mysql read the result from mysql, with the result being in the year/month/date format -- or, would you just get the unix_timestamp representation of the dates, and store the 10 int formats in the mysql tbl. you could then extract/select the date information from the tbls, and do all the date calculations in php... the downside to this is that you'd have to convert all the date information from mysql to a human readable format... thoughts/comments/etc... -bruce -Original Message- From: John Nichel [mailto:[EMAIL PROTECTED] Sent: Monday, September 26, 2005 11:48 AM To: php-general@lists.php.net Subject: Re: [PHP] mysql/php date functions.. bruce wrote: john... that appears to be it!! although i would have assumes it would have done a most significant bit fill with 0's... so my question also comes down to .. do i use the php date functions for date/time manipulation.. or do i use the mysql functions any thoughts/suggestions... -bruce Personal preference I guess.

[PHP] mysql/php date functions..
Hello Bruce, While the date functions are well documented - http://php.net/date - here is a little example to manipulate the date with php, rather than mysql: // set the new expiry date // DATE FUNCTIONS FOR THE EXPIRY MODULE // first perform date arithmetic $listingExpiry = mktime (0,0,0,date(m)+$monthsGoodFor,date(d)+1,date(Y)); // secondly, format the results for use in the database $expires = date (Y-m-d, $listingExpiry); // the actual update of the database with expires='$expires' ... should be below here The date format to be used in $expires depends on your database column structure.

Well, the truth is, computers are stupid, and you need to explain this kind of date format to him by rewriting such date in a way that a computer can understand... From where do you get such string? Can you ask the sender to send more uniform/standard date? I tried strtotime(%Y/%m/%d, 2005124) and this is the result: 1970/01/23. Look again at the function definition http://www.php.net/strtotime The second argument is timestamp (number of seconds since the unix epoch). So if you count 2005124 seconds from January 1 1970 00:00:00 GMT you would get to January 23 1970. hope this will help you a little, N:: smime.p7s Description: S/MIME Cryptographic Signature

Much appreciated all, I was kindda hopping that I missed something, some mysterious function... My solution to this is: if a value like 2005416 to ignore it and only look for 2005/4/16 or 20050416.

[PHP] date of file?
In addition to reading the names of the files in a directory, I also need to
read the date the file was modified.
Right now I've got this:
if ($handle = opendir($path))
{
$b=0;
while (false !== ($file[$b] = readdir($handle)))
{
$b++;
}
closedir($handle);
}
What function do I need to use to do this? I'm working in php4.

Burhan,
Thank you for replying, it is very much appreciated.
Perhaps I did not state what I needed as well as I should have. I'm
looking for the code which displays the date of the second Thursday of each
month on a web page. I have to insert this code at 5 different locations on
that webpage for different meetings. The scenario below describes how it
needs to work.
This month for example, September, the second Thursday is September
8, 2005. Up until midnight of September 8th the date on the webpage should
read September 8, 2005. When midnight arrives on September 8th, the date
displayed should change to October 13, 2005. If you can still help me I
would be grateful.
Oh, so you want to display the next available Thursday.
?php
$current_month_thursday = strtotime(2nd
Thursday,mktime(0,0,0,date(m)-1,0,2005));
if (strtotime(now) $current_month_thursday)
{
//First thursday has passed, show the first thursday
//of the next month
echo 'Next Meeting Date : ';
$next_month = mktime(0,0,0,date(m)+1,0,date(Y));
echo date(r,strtotime(2nd Thursday,$next_month));
} else {
// This month's second thursday hasn't passed yet
echo date(r,$current_month_thursday);
}
?
This prints :
[EMAIL PROTECTED] ~ $ php -q date2.php

Hope this helps, and please, reply to the list and not directly to me so

Having a heck of time getting anything to work, can anyone make a suggestion to the following. I need a webpage that displays 5 recurring meeting dates, i.e. the second Wednesday, Thursday, and Friday of each month in five different locations. Is there an easy (meaning code only, without using a database connection) way to get dates to display and automatically roll-over to the next months date when the actual date changes?

If it's MySQL, then just do an SQL query with a WHERE clause like this: WHERE updated DATE_SUB(NOW(), INTERVAL 1 YEAR) Jasper -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you have it in MySQL, there are a bunch of native MySQL functions to
format it on the select itself. See http://mysql.com/datetime
Or, if you want to manipulate it using PHP's functions, get MySQL to
return it to you as a UNIX timestamp.

I guess this is my day to be dense, but I don't really understand the question. One part I think I understand is that you don't see the benefit to using the DATE datatype to store your dates. The DATE datatype allows you to do many things with dates that would be difficult storing them as integers. For instance, what would you have to do to get the day of the week for a day 66 days prior to the stored date? If your date was stored in a DATE field, all you would have to do is: $result=mysql_query(SELECT DATE_FORMAT(DATE_SUB(`stored_date`, interval 66 days) ,%W) from tablename where...); $row=mysql_fetch_row($result); echo The day if the week is .$row[0]; ...if your dates are stored in integer fields, how would you easily come about a similar result?

Thanks, Ryan Subtracting the timestamps gives you 536457600 seconds, which is correct, but ( $dif_s / 60 / 60 / 24 ) gives you the actual number of days between these two dates. We say on *average* there are 365.25 days in a year, so 17 years (the correct age in years between these two dates) has about 17 * 365.25 = 6209.25 days. In actuality, there are 6209 days between these two dates. This seems close, but note that 6209.25 / 365.25 = 17 but 6209 / 365.25 = 16.9993155 And of course floor on 16.9993155 is still just 16. I don't think you can accurately calculate dates in this way without calculating the actual number of leap years between the two dates. Leap years occur every 4 years, and 17 / 4 = 4.25, so there were 4 leap years between 7/6/88 and 7/6/05 and therefore 365 * 17 + 4 = 6209 days, the actual number of days between these two dates. But note that ( 6209 - 4 ) / 365 = 17, which is correct. If you subtract the number of extra days due to leap years, then there are precisely 365 days in each year. It boils down to the fact that though there are on *average* 365.25 days in a calendar year, there are never *actually* 365.25 days in a calendar year. There are only either 365 or 366. kgt -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Actually, I was thinking it could be done inside a simple formula since
his original formula works on the leap years, ie. years divisible
by four. I guess the trick would be figuring out the actual seconds in
a year and doing most of the calculations on the unix timestamp.
Something is tickling the back of my brain on this but I can't see it
just yet. Eh...

[PHP] date problem
Hi all I have a database that holds car rental info DB: carrental_from (datetime field) carrental_to (datetime field) carrental_price (datetime field) [rates are per hour] The values I have are like: -00-00 00:00:00,-00-00 07:00:00,10 (all year around 00:00-07:00) -00-00 07:00:00,-00-00 00:00:00,20 (all year around 07:00-00:00) 2005-12-22 07:00:00,2006-01-02 00:00:00,15 (christmas period 00:00-07:00) 2005-12-22 00:00:00,2006-01-02 07:00:00,25 (christmas period 07:00-00:00) The user selects dates ($from - $to) to rent a car and he gets the price accordingly. I can do a (($to-$from)/60/60) and get the total number of hours but depending on the date and time you get a different result. Can anyone help with the SQL?

Re: [PHP] $date(l-m);
is it possible for $mydata-lastinsalled to have -MM-DD format? ie:
2004-05-31
you can use strtotime to convert it to unix timestamp to
compare...something like this:
$stamp = strtotime('2004-06-31'); // $mydata-lastinsalled
if($stamp = strtotime('1 year ago'))
{
echo 'less than 1 year';
}
else
{
echo 'over 1 year';
}
otherwise its impossible to tell if it is over one year without knowing
the day as well.. unless you guess and figure on the first of the month..

[PHP] Date() reporting wrong on OS X server intermittently
Hi There, I have an app which is installed across a dozen odd organisations, and one this week which is running on an OS X Xserve machine. Intermittently this week the PHP app has been seeing the wrong time. Shifting 12hrs at a time. The IT administrator who runs the box says that it's all okay, and it's synced correctly with a master server. Suspiciously enough some workmen had been in on the weekeend prior and may have cut/spiked the power to the box... (coincidence?) Is it possible that PHP could see a different date to the OSX GUI ? I wouldn't think it would be possible at all. Has anyone out there seen weird problems like this before ?

Re: [PHP] Date() reporting wrong on OS X server intermittently
The 12 hours seems suspicious to me since it's the difference between AM and PM.

Re: [PHP] Date() reporting wrong on OS X server intermittently
It could be flicking between GMT and local time, local time is 13 hrs difference. There's nothing on the server that would be changing an environment variable for the PHP app, so I'm pretty much ruling out interference from that. I still keep coming back to the server clock must be wrong but the IT guy assures me it isn't. Has anyone seen an error in PHP when it's gotten the date wrong. I can't imagine this ever happening.
