PHP Scandir returns extra periods

Question

So I am trying to build a script that scans a directory and returns random images to be used as backgrounds.

The php looks like this:

$dir = \"views         


        

Answer 1

Use glob() so you can filter the files.

$files = glob('views/img/bg/*.jpg');
$random = $files[array_rand($files)];

Since you're specifying *.jpg, $files contains only JPG files and you don't need to remove the . and .. items.
