How can you effectively filter out "." and ".." files when using scandir in PHP?

When using scandir in PHP to list files in a directory, it will also return "." and ".." which represent the current directory and parent directory. To filter out these entries, you can use a simple if statement to check if the file name is not equal to "." or ".." before processing it. 

$directory = "path/to/directory";
$files = scandir($directory);

foreach($files as $file){
    if($file != "." && $file != ".."){
        // Process the file here
        echo $file . "<br>";
    }
}
