How Can I List All Files in a Directory Using PHP, and Exclude Hidden Files?

Listing All Files within a Directory Using PHP

To retrieve a listing of files within a specific directory, PHP provides a versatile function known as scandir. This function scans the specified directory and returns an array containing the names of all files found within.

Implementation

To list all files in a directory named "usernames/," you can utilize the following code:

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

Displaying File Names as Hyperlinks

To create hyperlinks for each file name in the array, you can iterate over it using a loop:

foreach ($files as $file) {
  echo "<a href='$path/$file'>$file</a><br>";
}

Excluding Hidden Files from Results

By default, scandir also includes hidden files (files starting with a dot) in its results. To exclude these hidden files, you can use the array_diff function to remove "." and ".." from the array:

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