如何使用PHP递归地将所有具有特定名称的文件包含在文件夹中？

Question

Suppose I have a folder named parent In there, there are many subfolders like child1 , child2 etc. Some of these "child" folders have a file in them called module.php . How can I recursively check all subfolders of the parent folder and include all files named module.php in my application?

I tried the below and can't figure out what's wrong:

if ( !function_exists( 'glob_recursive' ) ) {
  function glob_recursive( $pattern, $flags = 0 ) {
    $files = glob( $pattern, $flags );
    foreach ( glob( dirname( $pattern ) . '/*', GLOB_ONLYDIR|GLOB_NOSORT ) as $dir ) {
      $files = array_merge( $files, glob_recursive( $dir . '/' . basename( $pattern ), $flags ) );
    }
    return $files;
  }
}

foreach ( glob_recursive( locate_template('/lib/modules/*/module.php' ) as $module ) {
  require_once $module;
}

Although it sounds like a bad design to include all files, it is possible:

$directory = new RecursiveDirectoryIterator('path/to/project/');
$recIterator = new RecursiveIteratorIterator($directory);
$regex = new RegexIterator($recIterator, '/\/module.php$/i');

foreach($regex as $item) {
    include $item->getPathname();
}

Btw, this example is derived from a comment in the PHP manual . To make it working, make sure that all sub folders are readable by PHP in that folder. If cannot make this sure you will have to write a custom recursive function for that (but this is unlikely).

Again, what you are doing is not a good design and will lead to problems (earlier than you might think). If you are following the OOP style, a better approach would be to use the autload mechanism of PHP.
