Answer 1

Check out the glob function for directory listing, and use this for removing the extension:

substr($filename, 0,strrpos($filename,'.')

Answer 2

<?php
foreach (new DirectoryIterator('directory') as $fileInfo) {
        if($fileInfo->isDot()) continue;
    $regex = '/\.\w+/';
    echo preg_replace( $regex, '', $fileInfo->getFilename() ) . '<br>';
}

Answer 3

function filename_part($f) {
    return pathinfo($f, PATHINFO_FILENAME);
}

$result = array_map("filename_part", scandir($directory));
