How can the file_get_contents function be used to read the contents of a directory in PHP, and what are the limitations or considerations to keep in mind?

To read the contents of a directory in PHP using the file_get_contents function, you can use the opendir function to open the directory, loop through its contents using readdir, and then use file_get_contents to read the contents of each file. Keep in mind that file_get_contents is used to read file contents, so it can only be used to read files within the directory, not subdirectories. 

$dir = 'path/to/directory';
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if ($file != '.' && $file != '..') {
                $content = file_get_contents($dir . '/' . $file);
                echo $content;
            }
        }
        closedir($dh);
    }
}
