do you actually have a datetime field or a varchar field?

on a datetime field, use the convert in the query itself:

select convert(varchar(40), yourfield, 106) from yourtable
resp:
select replace(convert(varchar(40), yourfield, 106) , ' ' , '/') from yourtable

You could try working with strtotime, but I doubt it will accept that date format. strptime should when your locale is set on english

Try:

$array = strptime($date, '%b %e %Y %H:%M%r'); //(when using Oct 1 2006)
or
$array = strptime($date, '%b %d %Y %H:%M%r'); //(when using Oct 01 2006)

$stamp = mktime($array['tm_hour'], $array['tm_min'], $array['tm_sec'], $array['tm_mon'], $array['tm_mday'], $array['tm_year']);

echo date('d/M/Y/, $stamp);

I would recommend against changing your timestamp field.  Keep it in your database and update the time by using update tablename set mydatefield = NOW() where myotherfield = y;

When formatting the string, the database has very powerful formatting capabilities.  The sql I would use for the above would look like:

select date_format(mydatefield, '%b %d %Y %h:%i%p') as formatteddate from tablename where myotherfield = 'foo'; and that would give you an output of Oct 24 2006 12:00AM.  There are many other formatting parameters that you can give the date_format function.

I find it is best to use the database whereever possible to do date and time formats, along with date and time calculations.  This then frees up php to actually process the other data.

datetime

>>select convert(varchar(40), yourfield, 106) from yourtable...

will convert(varchar(40), ...) will in a query string for PHP?

>>You could try working with strtotime

I will take a look at this...

%b = Abbreviated month name (Jan..Dec)
%d = Day of the month, numeric (00..31)
%Y = Year, numeric, 4 digits
%h = Hour (01..12)
%i = Minutes, numeric (00..59)
%p = AM or PM

do you want my Senior Programmer to kill me.  Our database is used by a large number of people and other web applications so changing it will cause more problems that good so your answer is no.

when i try using convert() i get this:

Warning: mssql_result() [function.mssql-result]: DateIn field not found in result in c:\Inetpub\wwwroot\prelease\index.php on line 543

My query:

$query = "SELECT CONVERT(varchar(40),DateIn,106) FROM tblBillables, tblItem WHERE tblBillables.BillableID = tblItem.BillableID AND tblBillables.NameID = ".$_SESSION['user_info']['persid']." AND tbl.Item.BillableID = ".$_GET['bid']." ORDER BY tblItem.Day, tblItem.Month";

Ellandrd, by running the convert you are changing your datetime field to a varchar with a length of 40.  If your Senior Programmer is going to kill you, then I suggest you start running immediately because he's after you...Lol.

By running the date_format() code as provided, you will find that your formatting of the information will come out nicely.  I must clearly state though that by running the date_format function, you will not change any data in the database, you are merely changing the way it's outputted at runtime.  For example:

select date_format(mydatefield, '%b %d %Y %h:%i%p') as formatteddate from tablename where myotherfield = 'foo';

and select date_format(mydatefield, '%M %d %Y %H:%i:%s') as formatteddate from tablename where myotherfield = 'foo'

will return two seperate formats of the date, but the data in the data will remain unchanged.

I would never provide code that would change the integrity of your data...just the way it looks when you output it.

Hope this helps.

but the data in the data should read but the data in the database.

Commented:
umm, sorry it should be uppercase.  select DATE_FORMAT(`mydatefield`, '%b %d %Y %h:%i%p') as formatteddate.

If that doesn't work, what version of mysql are you running?

Author

Commented:
its not MYSQL its MSSQL

Ok ive managed to kinda workaround it using explode().  its probably not the best or most efficient way but none of the solution/ functions provided seem to work.

my "workaround" is as follows:

$parts = explode(' ',$datein);
echo $parts[1].'/'.$parts[0].'/'.$parts[2];

Thanks to everyone who took some time to help me...
