Parsing Directory Tree

Anon

I have a recursive function that parses and prints out a directory tree starting at a specified 'root', but I changed the function to return the tree as an array, starting at the 'root' and having all subdirectories next in the array, and so on (e.g., '/','/images','/images/project','/html','/html/data',etc) and it does not work. Any help is appreciated!

er.....code please?

Something to the effect of ...

function allDirs($dir)
{
$allDirs = arrayOfDirs($dir);
for($n = 0; $n < count($allDirs); $n++)
{
$dirPath = $dir . "/" . $allDirs[$n];
print("$dirPath<br>\n");
allDirs($dirPath);
}
}

function arrayOfDirs($dir)
{
chdir($dir);
$open = opendir($dir);
while($file = readdir($open))
{
if(is_dir($file) && $file != "." && $file != "..")
$dirs[] = $file;
}
closedir($open);
return $dirs;
}

And you also need to tell us what's not working...

But my guess right now is that you don't need

chdir($dir);

when the function allDirs($dir) is changed to return an array, only the top level directories are returned.

for example, if i had the directory tree:

/images
/photos
/prom
/project
/english
/beloved
/math
/calculus
/profile

the original function as given in earlier posting prints out:

/images
/images/photos
/images/photos/prom
/project
/project/english
/project/english/beloved
/project/math
/project/math/calculus
/profile

if i change the function to return an array, it only returns the array:

$directories[0] = "/images"
$directories[1] = "/project"
$directories[2] = "/profile"

i'm pretty sure the problem has to do with the recursive function call. and chdir($dir) is very necessary -- i accidently removed it once and it didn't work at all.

thanks for all your help guys~~~

!!!!! FORMATTING PROBLEM WITH FIRST !!!!!

when the function allDirs($dir) is changed to return an array, only the top level directories are returned.

for example, if i had the directory tree:

/images
--/photos
----/prom
/project
--/english
----/beloved
--/math
----/calculus
/profile

the original function as given in earlier posting prints out:

/images
/images/photos
/images/photos/prom
/project
/project/english
/project/english/beloved
/project/math
/project/math/calculus
/profile

if i change the function to return an array, it only returns the array:

$directories[0] = "/images"
$directories[1] = "/project"
$directories[2] = "/profile"

In your for loop:

$dirPath = $dir . "/" . $allDirs[$n];
print("$dirPath<br>\n");
allDirs($dirPath);
}

You're not assigning the return value of allDirs($dirPath); to anything...that's why you don't get the children directories.

thanks, lemme redo that and modify a little and see if i get what i want ... good eyes. its a 1200+ line program im writing and sometimes i just miss things 😛

Anon
