Counting Images in a Folder

Recommended Posts

I'm using this code to count images in a folder on my website:

 

function countImgs() {
global $imgCount, $folder;
$dir = "./$folder/thumbnails/";
$imgCount = count(glob($dir . '*.jpg'));
}

 

Instead of counting all of the jpg's in the folder I want to count specific image sets in that folder. For example if my images are named: foo-01.jpg, foo-02.jpg, foo-03.jpg - I want to count all images that begin with the string 'foo'. Is this the correct way to check that? ->

 

function countImgs() {
global $imgCount, $folder;
$dir = "./$folder/thumbnails/";
$imgCount = count(glob($dir . 'foo*'));
}

 

Thanks
