So the above is returning the equivalent of the 11th day of the 30th month of 2004! You can use other PHP functions, as has been suggested, but you might also investigate the mySQL date formatting functions, as I believe they work perfectly well on input dates as well as output ones.

Use the string functions to manipulate it into the required format, explode() is one approach. If you're desperate search the archives, hundreds of variations of code to do this have been posted in the past.

Re: [PHP-DB] date conversions
Thank you for all your help.
Among all the variations I found this to be the clearest:
list($d,$m,$y) = explode(/,$testdate);
$mysqldate = date(Y-m-d, mktime(0,0,0,$m,$d,$y));
But I also thought the use of split instead of explode so you could nominate
multiple delimiters was good.
eg.
list($d,$m,$y) = split('[/.-]', $testdate);
Another variation was to hardcode the date results instead of using the date
function which is very simple:
eg.
$mysqldate = $y.'-'.$m.'-'.$d;
Sorry for asking a question that is obviously asked often.
Interesting comment on 'normal'. I suspect that numerically more of the
world uses dmy than mdy. There is a lot more of the world outside the US
than in it.
Thanks again for all your help.

Yeah, this is my problem with relyinig on strtotime(). If you don't give
it a format that it knows, it's going to give you random results (well, not
random, but undesireable). Seems like more of a crutch that leaves too
much chance of error for my taste. I prefer to be a little more explicit:
$testdate=30/11/2004;
list($day,$month,$year) = explode(/,$testdate);
echo date(Y-m-d, mktime(0,0,0,$month,$day,$year));
Try that out. mktime() produces a serial date/time just like strtotime()
but you have a little more control over what it's producing and subsequently
what gets piped into date(). This exact example is what I used once before
when arguing against using strtotime(). Most people are going to use a
'normal' format that strtotime() likes, but the format you're using
(european standard?) and just using the numbers is the one big instance that
strtotime() breaks.
Hope this helps. You should be able to get whatever date format you need
now.

Hi
I am needing to convert a d/m/y date such as 30/11/2004 into the format
that
mysql can use ie. 2004-11-20
If I try the following:
$testdate=30/11/2004;
echo date(Y-m-d, strtotime($testdate));
the result is - 2006-06-11
I can't find any other function apart from strtotime to do this.
Any ideas?
Thanks
Neil
