Hi!
Is there anything available like next() that will work on
multidimensional arrays?
I want to get a flat list of key and value of the current element of a
multidimensional array. I played around with next() now for an excessive
amount of time and it just doesn't seem to think in more than one
dimension. I also cannot make it to without missing some portions of the
multidimensional array.
Here is what I really want to do:
I copied the dirlist function from the php.net man page for scandir. The
function really works well, but returns a multidimensional array with
the folder names being the keys for the subarrays, whereas files have a
numerical key. What I need is a one dimensional array that has this
structure:
path_to_folder_as_key => filename1
path_to_folder_as_key => filename2
path_to_folder_as_key => filename3
path_to_folder_as_key => filename4
....
Since a folder will often contain more than 1 file, using the folder
path as the array key is not a good idea. The key can only be
associated to one value, so in your example the key
path_to_folder_as_key would have the value filename4 only.
A 2 dimensional array such as:
$the_files['path_to_folder_as_key'][0] = filename1
$the_files['path_to_folder_as_key'][1] = filename2
$the_files['path_to_folder_as_key'][2] = filename3
....
Should do it. If you really want to keep a one dimensional array you
could do the following:
$the_files[0] = 'path_to_folder,filename1';
$the_files[1] = 'path_to_folder,filename2';
...
And then when going through the array:
list($path, $file) = explode(',', $the_files[0]);
Good luck,
Che
I also spent quite some time with all the various array flattening
routines, but due to my lack of skill I cannot get those to keep the
keys in place or even combine them to a path. It is nice that something
like scandir is finally available, but PHP is still not very helpful in
that arena. Nah, it's not PHP, it's me being stupid. I also attempted
recursion with a function myself, but that ended up in total chaos and
desaster.
It would be great if one of you smart people could beat me out of this
.... again.
Best regards,
David
