As a response to a post by viajy at yoyo dot org on 10-Feb-2007 04:50, he posted the following code:
<?php
function listdirs($dir) {
static $alldirs = array();
$dirs = glob($dir . '/*', GLOB_ONLYDIR);
if (count($dirs) > 0) {
foreach ($dirs as $d) $alldirs[] = $d;
}
foreach ($dirs as $dir) listdirs($dir);
return $alldirs;
}
?>
It is not best practice to use recursive functions like that, so I wrote a safe (non-recursive)
function below:
<?php
function listdirs_safe($start)
{
$dir = $start;
$dirs = array();
$next = 0;
while (true)
{
$_dirs = glob($dir.'/*', GLOB_ONLYDIR);
if (count($_dirs) > 0)
{
foreach ($_dirs as $key => $_dir)
$dirs[] = $_dir;
}
else
break;
$dir = $dirs[$next++];
}
return $dirs;
}
?>
Example:
print_r(listdirs_safe('*'));
Output:
Array
(
[0] => Dummy folder/Dummy folder 2
[1] => Dummy folder/Dummy folder 2/Dummy Folder 3
[2] => Dummy folder/Dummy folder 2/Dummy Folder 3/4
[3] => Dummy folder/Dummy folder 2/Dummy Folder 3/Dummy folder 4
[4] => Dummy folder/Dummy folder 2/Dummy Folder 3/4/5
)
