RecursiveDirectoryIterator

$realpath = realpath('/path/to/file');


$fileObjects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($realpath),
                 RecursiveIteratorIterator::SELF_FIRST);

foreach($fileObjects as $key => $object){
    if($object->getFilename() === 'filename.png') {
        echo $object->getPathname();
    }
}

SELF_FIRST

echo shell_exec('find -name *');

scandir

<?php
    $dir    = '/tmp';
    $files = scandir($dir);
    print_r($files); 
?>

Array
(

    [1] => ..
    [2] => bar.php
    [3] => foo.txt
    [4] => somedir
)
