getting certain files from a directory

[rustylewis]

Ok ... I'm pretty new to php and have racked my little brain and searched the forums to no avail.

I want to get a list of file names containing certain text. I have a directory that contains images. xxx.full.jpg and xxx.thumb.jpg.

I want to get an array containing only the files that have thumb in the name.

How do I do that?

I can get a list of all files easy enough, I just don't know how to sort out only the ones that I want.

Thanks,
Rusty

Hope this helps.

$images = array();
$d = dir('directory/');
while (false !== ($entry = $d->read())) {
    if ($entry == '.' || $entry == '..') continue;
    if (stristr($entry, 'thumb')) $images[] = $entry;
}
$d->close();

print_r($images);

That's perfect!!!

Now I can put in a random thumbnail.

Ok ... I got all my code to work and I think I even understand most of it (sort of).

One question ...

if ($entry == '.' || $entry = '..') continue;

Am I right that this looks at the directory listing and just says keep going? And I guess ... what would cause this to fail if this line was not there?

Just trying to understand it all ...

Thanks,

There are two entries in every directory that you don't want to proccess, a single dot representing the current directory and two dots representing lower level directory.

Thanks. I think I have achieved a small level of understanding.
