包含文件夹中的所有文件 - PHP

Question

I'm trying to include all files from a folder from another folder in php. Here is my current directory structure:

> folder1
  main.php
> folder2
  > folder3
  someFile.php
  someFile2.php
  someFile3.json

I tried doing:

include "../folder2/";

and this(only includes php files):

foreach (glob("classes/*.php") as $filename)
{
    include $filename;
}

From main.php , I want to include all of folder2/ including the sub folder: folder3 as well as the php and json files inside folder2/ . I have looked at other stack overflow questions and know about the for loop method but haven't figured out a way to include different file types(.php, .json, etc...) and sub directories. Any help is appreciated. Thanks!

PHP's include shouldn't be used for other file types, like .json . To extract data from those files you'll want to read them using something like file_get_contents . For example:

$data = json_decode(file_get_contents('someFile3.json'));

To recursively include the PHP files in other directories you can try recursively searching through all directories:

function require_all($dir, $max_scan_depth, $depth=0) {
    if ($depth > $max_scan_depth) {
        return;
    }

    // require all php files
    $scan = glob("$dir/*");
    foreach ($scan as $path) {
        if (preg_match('/\.php$/', $path)) {
            require_once $path;
        }
        elseif (is_dir($path)) {
            require_all($path, $max_scan_depth, $depth+1);
        }
    }
}

$max_depth = 255;
require_all('folder3', $max_depth);
