Is there a way in PHP to do this?
Thank you very much.

I think you should change from using 'rsort' ( a SORT function) to
'array_reverse', a simple reverse function.
Your example of what you desire is wrong.
24-7-2013 will give you the 2013-24-7 that you want.
Here is my sample code. Try it yourself.
<?
$dag = array("24/7/2013");
echo "Began with: ";var_dump( $dag);
echo "<br>**********<br>";
echo "Try using rsort<br>";
$dagparts = explode("/",$dag[0]);
echo "dagparts: ";
var_dump($dagparts);
echo "<br>**********<br>";
rsort($dagparts);
echo "sorted dagparts: ";
var_dump($dagparts);
echo "<br>**********<br>";
$newdag = implode("-",$dagparts);
echo "newdag: ";
var_dump($newdag);
echo "<br>**********<br>";
echo "Now use array_reverse<br>";
$dagparts = explode("/",$dag[0]);
echo "dagparts: ";
var_dump($dagparts);
echo "<br>**********<br>";
$dagparts = array_reverse($dagparts);
echo "REVERSED dagparts: ";
var_dump($dagparts);
echo "<br>**********<br>";
$newdag = implode("-",$dagparts);
echo "newdag: ";
var_dump($newdag);
echo "<br>**********<br>";

Use this:
echo preg_replace('#(\d{2})/(\d{2})/(\d{4})#' , "\\3-\\2-\\1", '24/07/2013'
); RESULT => 2013-07-24

It would be better if you reformatted first since this is ambiguous when
you have the following date:
6/7/2013
Here's a completely unambiguous solution:
<?php
$old = '24/7/2013';
$paddy = function( $bit ){ return str_pad( $bit, 2, '0',
STR_PAD_LEFT ); };
$new = implode( '-', array_map( $paddy, array_reverse( explode(
'/', $old ) ) ) );
echo $new."\n";
?>
Cheers,
Rob.

The original question was about reformatting a European (Day/Month/Year)
date. Your solution does not address this problem. Mine assumes the
European date format explicitly.

date. Your solution does not address this problem. Mine assumes the
European date format explicitly.
Jomali,
Your solution is broken. The original poster requested the following:
>>>> What I want is a way to rewrite contents of a variable like this:
>>>>
>>>> From 24/7/2013 to 2013-07-24
Your solution makes use of the strtodate(). A useful strategy EXCEPT (as
you have already noted) the date follows the European formatting rules
of dd/mm/yyyy since the 24 as the first number makes that obvious.
HOWEVER, you failed to realize the following (from the PHP online manual):
Dates in the m/d/y or d-m-y formats are disambiguated by looking
at the separator between the various components: if the separator
is a slash (/), then the American m/d/y is assumed; whereas if
the separator is a dash (-) or a dot (.), then the European d-m-y
format is assumed.
And so, as soon as an abiguous date arises, the solution will be
incorrect because strtotime() will presume an American format due to the
appearance of the slash instead of the hyphen. It is dangerous to rely
on magical functions like strtotime() unless you completely understand
how ambiguity is resolved.
Another solution that was posted only re-ordered the elements and you
likely noticed that there is a single digit 7 in the source date and in
the response date it has been 0 padded to conform to the standard
yyyy-mm-dd date format. The other solution does not do this and so it is
also incorrect.
And so it follows, that my solution, thus far, is the only solution
posted that actually meets the requirements. Why you think my solution
does not perform is beyond me since a simple run of the code would
output the correct answer (yes I did test)-- mine also presumes the
European ordering for all input with components separated by a slash.
Cheers,
Rob.
