How Do I Get File Names from a Directory in PHP?

Retrieving File Names from a Directory in PHP

In PHP, obtaining the file names within a directory is a common task. Various approaches exist for achieving this.

DirectoryIterator

The recommended method is DirectoryIterator, which offers an object-oriented interface to iterate over the directory's content.

<code class="php">foreach (new DirectoryIterator('.') as $file) {
    if($file->isDot()) continue;
    echo $file->getFilename() . '<br>';
}</code>

scandir

An alternative is scandir, which returns an array of file names.

<code class="php">$files = scandir('.');
foreach($files as $file) {
    if($file == '.' || $file == '..') continue;
    echo $file . '<br>';
}</code>

opendir and readdir

Using opendir and readdir is another option.

<code class="php">if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if($file == '.' || $file == '..') continue;
        echo $file . '<br>';
    }
    closedir($handle);
}</code>

glob

Glob can be employed for more complex file matching.

<code class="php">foreach (glob("*") as $file) {
    if($file == '.' || $file == '..') continue;
    echo $file . '<br>';
}</code>

Glob allows patterns, such as using an asterisk to match any characters or specifying partial file names to filter results.
