Hi, I have the next problem. I want to sort the array for the key,
using a function. I have been looking for a function to operate with
arrays, but I haven't found anything.

Ej:

Array
(
[43] => 001480-----3-----04/11/2003
[50] => 001000-----3-----04/11/2005
)


I want to convert this array to:

Array
(
[1] => 001480-----3-----04/11/2003
[2] => 001480-----3-----04/11/2003
)

Thaks.

Wow you must have looked really hard!
Did you even put
php array sort key
into Google?

IMO this is not even sorting, but "flushing" some array.
How hard can this be?

function arrayFlush($mixArray){
foreach($mixArray as $obj) $temp[] = $obj;
return $temp;
}

Or am I missing something?

According to your example you want to sort an array discarding keys.
Surprisingly, the function is called "sort()". From manual:


sort - Sort an array available since: PHP 3, PHP 4, PHP 5

usage:
bool sort ( array &array [, int sort_flags] )

Note: This function assigns new keys for the elements in array . It will
remove any existing keys you may have assigned, rather than just reordering
the keys.

Not really, we have 2 different values here, I guess it's just a
preview/part of an array. Array index 50 would come before index 43 BTW,
001000 before 001480 offcourse trumps a later date. Or it's a typo. In
either case, difficult to interpret with 100% certainty. I'd advise the up
to look at the different functions able to sort arrays in
<http://nl2.php.net/manual/en/ref.array.php>

Offcourse, this dubious example could mean the OP wants to sort by the
ending date rather then the string value. Which would be something like:

function __mysort($a,$b){
$a_cmp = preg_match('%\d+/d+/\d+^%',$a,$a_match) ?
strtotime($a_match[0]):0;
$b_cmp = preg_match('%\d+/d+/\d+^%',$b,$b_match) ?
strtotime($b_match[0]):0;
if($a_cmp == $b_cmp) return 0;
return ($a_cmp < $b_cmp) ? -1 : 1;
}
usort($array,'__mysort');
