Topic: PHP + Arrays

[Canuck]

Hi,

Ive been trying to modify my php slideshow so that in can handle multiple directories.

I read in the directory names and want to create arrays for them with the same name, but I cant figure out how to do it.

I store the dir names in an array, and loop through the array to store the dir name in a variable.

$array_name = $dir_array[$i];

$array_name = array();

I try to create an array with the name of the array being $array_name, but $array_name has the value Array.

I cant seem to figure out how to accomplish this.

Any help would be greatly appreciated.

Thanks

I'm confused by what you're trying to accomplish (after reading that 3 times).  Maybe I'm just tired.

But if you're running those 2 lines of code after each other, the second one is going to reinitialize the array back to an empty array.  I assume you know this, but obviously I'm missing something here.

$dir_names = array(
  'dir1',
  'dir2',
  'dir3',
  // ...
);

$array_name = array();
foreach($dir_names AS $dir_name)
  $array_name[$dir_name] = array();


I think at least thats what you are talking about.  Then you could do something like

$array_name['dir1'][] = 'ober.xxx';


Or whatever to load the actual files into that directory.  If you then wanted to output all the files:

foreach($array_name AS $dir => $files)
  foreach($files AS $file)
    echo $dir, '/', $file;

Let me try to explain it again.

I want to read the names of the directories in the current directory and stores those names into an array, which I do (in $dir_array[]).  So that array would hold the names of the directories.

I now want to loop through $dir_array[] and create arrays with the names of those directories.

So I would want an array for every directory, the array having the same name of the directory.

Then I think you want to use variable variables:

$array_name = $dir_array[$i];

$$array_name = array();
