Open the directory in php and output directory file to achieve the code

The opendir () function opens a directory handle that can be used by closedir (), readdir (), and rewinddir ().

// If you want to sort the directory alphabetically as one

$ files1 = scandir ($ dir); // List the contents into the array in ascending alphabetical order
$ files2 = scandir ($ dir, 1); // Sort the contents into the array in descending alphabetical order
