list only directories

Copy linkTweet thisAlerts:

I have a script that I am using to list all directories and files.

I am trying to seperate out the files and folders all I want is the names of the folders.

Does anyone know of a way to do this?

@dk_zero-coolJan 27.2010 — Just use the is_dir and is_file to check whether it is the one or the other.

[code=php]if($objDir = opendir(".")) {
while(($item = readdir($objDir)) !== false) {
if(is_dir($item) && $item != "." && $item != "..") {
echo $item." is a directory";

}elseif(is_file($item)) {
echo $item." is a file";
}
}
closedir($objDir);
}[/code]

I agree. It seems glob() has been around since 4.3.0 and is a killer function, but many people continue to use the other methods. I know when I first saw the command in a function listing by name only, I assumed it tied into a wacky database type i.e. blob's and clob's! Funky name until I realized it's like a libc function. It really does save effort using it, plus any time a language construct or function can do it why not use it?

I always appreciate more efficient code.

@MindzaiJan 28.2010 — It's been around as a unix program for a long time as well, so I'm surprised more people aren't aware of it, but as you say most code examples you see use the readdir approach. It's quite rare that I ever use readdir, glob is just so much cleaner.

@dk_zero-coolJan 28.2010 — Well. I would think that the reason people use the readdir instead of glob, is the same reason that people don't use preg_split and preg_replace if it can be done with explode and str_replace.

In my case however, I just didn't know that one ?

@NogDogJan 28.2010 — Just a tip: if you only want the file names (no path info), you can change to the directory before doing the glob().
[code=php]
$cwd = getcwd();
if(chdir('path/to/files'))
{
$dirs = glob(*, GLOB_ONLYDIR);
chdir($cwd);
}
[/code]
While it's no longer a one-liner, it still avoids having to do any looping in the script.

Success!
