PHP list of specific files in a directory
use php scandir($dir) and get only images!

So right now I have a directory and I am getting a list of files

$dir_f = "whatever/random/";
$files = scandir($dir_f);

That, however, retrieves every file in a directory. How would I retrive only files with a certain extension such as .ini in most efficient way.

PHP has a great function to help you capture only the files you need. Its called glob()

glob – Find pathnames matching a pattern

Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.

Here is an example usage –

$files = glob("/path/to/folder/*.txt");

This will populate the $files variable with a list of all files matching the *.txt pattern in the given path.
