How to pick up directories recursively?

Question

How do I recursively grab all files *.php? With the code below caught all that are root, but wanted to get from all directories.

I tried to use RecursiveDirectoryIterator, or use some functions I found on Soen, kind of, but nothing...

function getPageFiles()
{
    $directory = '';
    $pages = glob($directory . "*.php");
    //print each file name
    foreach ($pages as $page){
        $row[$page] = $page;
    }
    return $row;
}

Look, this example shows the files in layered subdirectories within the specified scope.

<?php

$dir_iterator = new RecursiveDirectoryIterator("../");
    $iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST);
    $Regex = new RegexIterator($iterator, '/^.+\.php$/i', RecursiveRegexIterator::GET_MATCH);


    foreach ($Regex as $file) {
        foreach($file as $final){
            echo $final, "<br/>";   
        }
    }

?>   

In this case, all files .php who are in the pastas/subpastas directory pointed, will be displayed.

On the very page of PHP.net There are usually examples at the bottom of the page. Although this is an example from there, I added a specific line to do what you wanted. I hope it’s useful to you.
