[PHP] Date functions differences between php 4 and 5
Dear All, I was wondering if there are any major date function changes between php4 and 5. When I say date function I mean mktime() , date() ,strtotime() etc. Here is my dilemma, I've upgraded from php4 to php5. there is some very old legacy code that is not working correctly. Specifically on our sales calendar. Some task show up but most don't. I have the old site and the new upgraded site on the same db. When entering a new task on the calendar, tasks enter w/ the new system show up on the new system and not on the old. Most old tasks don't show up on the new. The code is a pretty bad hack (why use the echo statement once when you can use it 207 times). www:/srv/www/htdocs/admin # grep -ic echo calendar/calendar.html 207 Any knowledge of this would be greatly appreciated.

RE: [PHP] Date functions differences between php 4 and 5
I just asked this a bit ago. Time and Date seem to be the same, but strtotime is definitly different, as that was what broke in my script in php4, and I was told it worked as expected in php5. -Original Message- From: Chris [mailto:[EMAIL PROTECTED] Sent: Thursday, March 22, 2007 7:18 PM To: Paul Nowosielski Cc: php-general@lists.php.net Subject: Re: [PHP] Date functions differences between php 4 and 5 Paul Nowosielski wrote: Dear All, I was wondering if there are any major date function changes between php4 and 5.

[PHP] mysql/php date functions..
hi... can anybody point me to a good/basic tutorial (tested) for php/mysql date functions... basically, i want to store a date/time in a column, and be able to read it, manipulate it, and update the table. i've seen various articles/sample code, but i'm looking for something that i cna pretty much rewrite and use without having to do a lot of initial testing.. if i create the functions myself, i'm going to need to do initial testing to make sure i haven't screwed something up, and i'm on a time crunch!! thanks -bruce [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi Bruce! MySQL and PHP both have extensive built-in date functions that are clearly documented and extraordinarily easy to use. For the vast majority of situations, there is no need to manually write any custom date-handling code. The decision to use MySQL or PHP to manipulate a date for a given instance depends largely on the particulars of that situation. For instance, if you want to increment a MySQL date column by one day, it would likely be better to use the MySQL date functions to do it, because to use PHP, you have to read the date, manipulate it, then write it back, whereas if you use a SQL statement, you can do it with one DB call.

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.

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.

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.

[PHP] date functions
Hi, You might already be fed up with my posts but I'm a complete PHP newbie and find these groups are the best way to learn! Anyway I have the database date in the format: -mm-dd hh:mm:ss e.g. 2004-02-24 07:57:59 but when in some situations I only want to show the user the date in the format dd-mm- what is the correct / best php function to use for this purpose ? Cheers. Matt

RE: [PHP] date functions
Depending on your database engine (which you didn't mention in your post), some allow you to format the date however you want it as you pull it out of the database in your sql query. I always find this to be the easiest way to do it. That way you don't have to worry about formatting the data after it has been output from your query.

You can either use the date functions or regexps, I would recommend the
date functions, they may be a bit slower but they are more flexible and
easier to read:
$timestamp = strtotime('2004-02-24 07:57:59');
$date = date('d-m-Y', $timestamp);
Also, it would be best to try and get the date in a timestamp instead of
a formatted string, check if your database can do this. If so then you
can skip the strtotime step above. If you are using MySQL and the date
field is one of the date formats (ie. not char/varchar) take a look at
MySQL's date formatting functions[1].

Re: [PHP] date functions
Patrick Off the top of my head... Convert both date1 and date2 to unix timestamps, and subtract one from the other. That will give you the number of seconds between them. Then, convert to hours, minutes, etc as required.

[PHP] Date functions Unic Epoch
Hi! Say, has anybody re-written the date funtions so they work with any date and not be crippled by the unix timestamp range limit? I am looking for a function which will do the equivalent of date(w,mktime(0,0,0,8,30,1934)) but that will actually *work*. Does anybody know a way to return which day of the week (0-7) it is for dates outside the unix timestamp range? I wish this stuff would be build into PHP.

Re: [PHP] date functions
Well you could do two str2time() calls like this: # Two Dates to Compare # $date1 = strtotime(Oct 18, 2002); $date2 = strtotime(Jan 18, 2002); # Assign the earliest date and laterdate to variables # $earlyDate = ($date1 $date2) ? $date1 : $date2; $laterDate = ($earlyDate == $date1) ? $date2 : $date1; # Computes to find how many days are between the two dates # $daysBetween = ceil(($laterDate - $earlyDate)/(60*60*24)); echo $daysBetween; There's probably an easier way of doing this, but hey it works! ;) Rick You will never be happy if you continue to search for what happiness consists of.

Pretty much common sense, right? How about something like this:
// $timestamp1 = starting date (unix timestamp)
// $timestamp2 = ending date (unix timestamp)
// $weekday = day we're counting (0 = Sunday, 1 = Monday, etc.)
function weekdaysBetween ($timestamp1, $timestamp2, $weekday)
{
return floor(intval(($timestamp2 - $timestamp1) / 86400) / 7)
+ ((date('w', $timestamp1) = $weekday) ? 1 : 0);
}
