I looked at that splice function a bit more and at arrays as well. I
still don't get why the position matters. To me the key of an array is
like the autoincrement primary key on a table. You can't just start
messing around with it and expect everything to be fine.
Sometimes it matters because you want things to be in a particular
order. In this case, I have an array with a whole bunch of form values
for a unit test. I want to rename one of the keys, but I want the
values to be in the same order. Of course there are other ways to do
it, which is probably why no one has bothered to code
array_key_replace().
What you could do is split the array into two numerically keyed arrays.
Each array can then be referenced using the same key and you can then
change the value of the desired original key in the array with the
original keys. Once done you glue the two together by specifying the key
for the glued array.
That preserves keys (except for the one you changed, of course) as well
as order and can handle duplicates if there would be any.
True, and without jumping through as many hoops as my hack involving $map.
$keys = array_keys( $set );
$values = array_values( $set );
$replace = array_search( 'bean', $keys );
if ( $replace !== FALSE ) {
$keys[ $replace ] = 'legume';
}
$set = array_combine( $keys, $values );
Thanks, David.
