getting all sub-directories

[laredotornado@zipmail.com]

Hi,

I'm using PHP 4.4.4 with Apache 2 on Fedora Core 6 Linux. Given a
directory, how would I get all sub-directories? I found "scandir" but
that only applies for PHP 5 and I think it returns both files and
folders, whereas I only want the folders.

Thanks for any help, - Dave

Re: getting all sub-directories

This function will do it:

function getFilesByType( $dir, $type = 'dir')
{
if (($dh = opendir($dir)) === false) {
trigger_error(' opendir', E_USER_ERROR);
} else {
if ($dir[strlen($dir) -1] == DIRECTORY_SEPAR ATOR) {
$sep = '';
} else {
$sep = DIRECTORY_SEPAR ATOR;
}
$list = array();
while (($ent = readdir($dh)) !== false) {
if ($ent == '.' || $ent == '..') continue;
if (filetype("$dir $sep$ent") == $type) {
$list[] = "$dir$sep$e nt";
}
}
closedir($dh);
return $list;
}
return false;
}

PHP 4 is dead, PHP 6 on the rise. It's time for an update.

I suggest to update to PHP 5 and use the iterators from the SPL. Then
with a simple 'foreach' loop you can easily loop through arbitrarily
deep nested tree structures and search for whatever you like, e.g.

$result = array();
foreach (new DirectoryIterat or($yourPath) as $item) {
if ($item->isDir() && !$item->isDot()) {
$result[] = $item->getPathname( );
}
}
