There are many ways of retrieving folder content like glob, scandir, DirectoryIterator and RecursiveDirectoryIterator, personaly I would recommend you to check DirectoryIterator as it has big potential.

Example using scandir method

$dirname = getcwd();

$dir = scandir($dirname);

foreach($dir as $i => $filename)
{
    if($filename == '.' || $filename == '..')
        continue;

    var_dump($filename);
}

Example using DirectoryIterator class

$dirname = getcwd();

$dir = new DirectoryIterator($dirname);

foreach ($dir as $path => $splFileInfo)
{
    if ($splFileInfo->isDir())
        continue;

    // do what you have to do with your files

    //example: get filename
    var_dump($splFileInfo->getFilename());
}

Here is less common example using RecursiveDirectoryIterator class:

//use current working directory, can be changed to directory of your choice
$dirname = getcwd();

$splDirectoryIterator = new RecursiveDirectoryIterator($dirname);

$splIterator = new RecursiveIteratorIterator(
    $splDirectoryIterator, RecursiveIteratorIterator::SELF_FIRST
);

foreach ($splIterator as $path => $splFileInfo)
{
    if ($splFileInfo->isDir())
        continue;

    // do what you have to do with your files

    //example: get filename
    var_dump($splFileInfo->getFilename());
}
