Answer 1

The manual clearly says that:

readdir
Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem.

What you can do is store the files in an array, sort it and then print it's contents as:

$files = array();
$dir = opendir('.'); // open the cwd..also do an err check.
while(false != ($file = readdir($dir))) {
        if(($file != ".") and ($file != "..") and ($file != "index.php")) {
                $files[] = $file; // put in array.
        }   
}

natsort($files); // sort.

// print.
foreach($files as $file) {
        echo("$file 
\n");
}
