"absolute path of the direcory",
"struct" => array());
As you can see the path itself is put into the "name" field of the
array while the "struct" field is an array.
For each file the function finds it adds an entry to the next
"struct" field containing the files' name.
For each directory the function finds it adds an entry to the next
"struct" field containing a new array of the described structure.
There are two exceptions:
unaccessible directories have a scalar struct = -1
empty directories have a scalar struct = -2
After the function has recursed the whole directory it returns the array
-- Example ---------------------------------------------------------------------
When I recurse a part of my apache htdocs directorytree which contains
some images the array looks like this (PHP comments not included).
Each subarray and therefore each subdirectory is indicated by leading
whitespace:
name = /usr/local/apache/htdocs/media // this is where we start
struct
name = /usr/local/apache/htdocs/media/.1 // first entry is a dir
struct
name = /usr/local/apache/htdocs/media/.1/.3 // same here, dir again
struct // this dir has content
0 = 40.jpg // 0 is the arrays key
1 = tn_40.jpg // the *.jpg's are the value
2 = 41.jpg
3 = tn_41.jpg
4 = 42.jpg
5 = tn_42.jpg
6 = 43.jpg
7 = tn_43.jpg
8 = 44.jpg
9 = tn_44.jpg
10 = 45.jpg
11 = tn_45.jpg
name = /usr/local/apache/htdocs/media/.1/.4 // next subdirectory
struct = -1 // access denied!
name = /usr/local/apache/htdocs/media/.1/.5 // next subdirectory
struct // content again
0 = 81.jpg
1 = tn_81.jpg
2 = 82.jpg
3 = tn_82.jpg
4 = 83.jpg
5 = tn_83.jpg
6 = 84.jpg
7 = tn_84.jpg
8 = 85.jpg
9 = tn_85.jpg
10 = 86.jpg
11 = tn_86.jpg
12 = 87.jpg
13 = tn_87.jpg
14 = 88.jpg
15 = tn_88.jpg
name = /usr/local/apache/htdocs/media/.2 // next subdirectory
struct
name = /usr/local/apache/htdocs/media/.2/.6 // another subdir
struct = -2 // this one is empty!
