[RESOLVED] Getting certain files from folder

[lupus6x9]

Hi, this is rather lengthy and complicated, but I kind of need some help.

I would like to access a subfolder where images reside (something like [font="Lucida Console, Courier New"]./gallery_images/[/font]) and output all of the filenames in that folder that have the extensions of [font="Lucida Console, Courier New"]gif[/font], [font="Lucida Console, Courier New"]jpe[/font], [font="Lucida Console, Courier New"]jpg[/font], [font="Lucida Console, Courier New"]jpeg[/font], and [font="Lucida Console, Courier New"]png[/font], including those with capitalized extensions (like [font="Lucida Console, Courier New"]GIF[/font]).

For example...

DIRECTORY /path/to/script/gallery_images/
./index.php
./something.txt
./image1.png
./apples.gif
./file.JPG
./logo.jpe
./imageHandler.js

and output something like this:

The images in /path/to/script/gallery_images/ are...
<UL>
<LI>image1.png
<LI>apples.gif
<LI>file.JPG
<LI>logo.jpe
</UL>

Also, if it is possible, I would like to sort the files in the order that they were uploaded or last modified, even if they haven't been uploaded through PHP.

The images in /path/to/script/gallery_images/ are...
<UL>
<LI>image1.png - Uploaded 6 July 2008
<LI>apples.gif - Uploaded 4 July 2008
<LI>file.JPG - Uploaded 1 July 2008
<LI>logo.jpe - Uploaded 1 July 2008
</UL>

While I won't bother coding my sample to output exactly what it is you're looking for, I'll give you a nice head start. 😉

Think along these lines using glob():

$dir = $_SERVER['DOCUMENT_ROOT'].'/script/gallery_images/';
foreach (glob($dir."*.gif") as $filename){
	$fileGIF = basename($filename);
	echo $fileGIF;
}

I recently was told about glob in another post of mine.. Haven't looked back since. Nice double whammy function (goes into a directory AND fetches files). Niiiice!
You might be able to add some preg expressions into the glob mix (not sure though). But experiement with the above snippet. Functions like glob() and basename() can make coding so much easier.

Hope that helps..

Cheers,

Thanks!

And I found out how to use GLOB_BRACES to get multiple files. How can I make sure the files aren't case-sensitive?

Try modifying this line:

foreach (glob($dir."*.gif") as $filename){

to this!!

foreach (glob($dir."*.{gif,GIF,Gif,gIf,giF,GIf,gIF,GiF}", GLOB_BRACE) as $filename)

You may have to add any combination of gif, jpg, txt and god knows whatever else into the curly braces.. I know it's messy, but it works 🙂

Hope that helps out!

Cheers,

Alternative could be something like:

$dir = '/path/to/dir';
$ext = array('gif', 'jpg', 'jpeg'); // array of extensions to allow

if ($dh = opendir($dir)) {
		while (($file = readdir($dh)) !== false) {
				if(!in_array(strtolower(substr($file, strrpos($file, '.')+1)), $ext))
					continue;
				else {
					// do something with $file here
				}
		}
		closedir($dh);
}

I figured out how to do this already, but thanks!
