How Can I List All Files in a Directory Using PHP?

Obtaining File Listings with PHP

Question: How can you effectively list all files within a specified directory using PHP?

Answer:

To retrieve a list of files contained within a directory, PHP provides the scandir() function. This function takes the directory path as its input parameter and returns an array containing the file names.

Implementation Example:

$directory = 'usernames/';
$files = scandir($directory);

The $files array now contains a list of file names within the specified directory.

Additional Note:

If you wish to exclude the special directories '.' and '..' from the list, use the following approach:

$files = array_diff(scandir($directory), array('.', '..'));
