Glob not giving me any results

Question

I'm trying to use PHP's Glob to get a list of files based on a wildcard, namely the extension.

$images = glob('/content/big/'.$item['id'].'.{jpg,jpeg,png,gif}', GLOB_BRACE);

I know there is a file in this directory, namely: 23.png but it doesn't show in array $images. I don't have a clue why not. I've tried making the URL even more absolute (or explicit) like:

$images = glob('http://www.website.com/content/big/'.$item['id'].'.{jpg,jpeg,png,gif}', GLOB_BRACE);

Without result.

Could it be that Glob isn't installed properly inside PHP? Or is there another reason this doesn't give any results?

Answer 1

glob only works with paths on the server's file system, not URLs.

http://www.website.com/content/big/ may really be /var/www/site/content/big on the server, and that's the path you need to use.

Staring a path with a / makes glob look in your root for that folder, and I'm assuming there is no folder called /content/big/ on your server.

Try it like this (using a relative path from the server root):

$images = glob('content/big/'.$item['id'].'.{jpg,jpeg,png,gif}', GLOB_BRACE);

Or use an absolute path:

$images = glob('/var/www/site/content/big/'.$item['id'].'.{jpg,jpeg,png,gif}', GLOB_BRACE);

below is my implementation, single quotes did not work with the echo, but this works for me. Hope it helps!

            <ul>
                    <?php
                            foreach(glob('audio/*.mp3') as $audio){ echo "<li><a>$audio</a></li>";}
                    ?>
            </ul>
