Tips : Easy way to find a file in subdirectory with php

I’ve made a previus post on SPL using RecursiveIterator to parse Array. Today we will use this same RecursiveIterator with a DirectoryRecursiveIterator.

We have a directory with a lot of subdirectory like this and we want to find this file :) :

Directories SPL

So we are just executing a page which must include the file_to_find.php :

include(dirname(__FILE__)."/class.directorysearch.php");
 
directory = dirname(__FILE__)."/directory";
 
$search_directory = new DirectorySearch($directory);
path_file = $search_directory->find("file_to_find.php");
 
if($path_file !== false){
  include_once($path_file);
}

Let’s have a look to the class.directorysearch.php :

class DirectorySearch  {    
 
private
      $iterator,
      $directoryname; 
public function __construct($directoryname){
        $this->iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directoryname,RecursiveDirectoryIterator::KEY_AS_FILENAME));
    }
 
public function find($filename){
        foreach($this->iterator as $entry){
           if($filename == $this->iterator->current()){
            return $this->iterator->getPathName();
          }
        }
        return false;
    }
}

If we don’t use the KEY_AS_FILENAME with the recursiveDirectoryIterator we will have the whole path of the file in $this->iterator->current();

All of this is a basic example of the RecursiveIteratorIterator with the RecursiveDirectoryIterator. SPL is a very powerfull toolkit !
