The function glob() returns a set of file names or directories corresponding to a specific pattern. In the case in question glob("$pasta{*.jpg}", GLOB_BRACE) being $pasta = 'images/gallery/fruteira/';

The number of files inside the folder fruteira is given by count($arquivos)

From then on, it’s the minimum knowledge in PHP to understand the logic of the script :)

I created a small control for PHP paging (optionally can be done in javascript). Basically an offset variable is used that must be passed by the url, and this variable will determine which image should be printed. Adding I created an array to store part of the image url (to facilitate paging), small changes to the for loop, and two links were added to each next and one to previous.
