php scan directories in direcctories - php

Question

Problem it's in sub directories, i have many sub directories and sub sub directories, i need check them all, Maybe someone know how to help .
My code:
$mainFodlers = array_diff(scandir(self::PROJECT_DIRECTORY, 1), array('..', '.','__todo.txt'));
foreach ($mainFodlers as $mainFodler) {
if (is_dir(self::PROJECT_DIRECTORY . '/' . $mainFodler)) {
$subFolders = array_diff(scandir(self::PROJECT_DIRECTORY . '/' . $mainFodler, 1), array('..', '.','__todo.txt', 'share_scripts.phtml'));
} else {
$extension = $this->getExtension($subFolder);
if ($extension == 'phtml') {
$file = $subFolder;
$fileContent = file_get_contents(self::PROJECT_DIRECTORY . '/views/' . $file, true);
}
}
}

Because I cannot really determine the end result of your code it is hard to answer effectively but to solve the problem of nested folders you might wish to consider a recursiveIterator type approach. The following code should give a good starting point for you - it takes a directory $dir and will iterate through it and it's children.
/* Start directory */
$dir='c:/temp2';
/* Files & Folders to exclude */
$exclusions=array(
'oem_no_drivermax.inf',
'smwdm.sys',
'file_x',
'folder_x'
);
$dirItr = new RecursiveDirectoryIterator( $dir );
$filterItr = new DirFileFilter( $dirItr, $exclusions, $dir, 'all' );
$recItr = new RecursiveIteratorIterator( $filterItr, RecursiveIteratorIterator::SELF_FIRST );
foreach( $recItr as $filepath => $info ){
$key = realpath( $info->getPathName() );
$filename = $info->getFileName();
echo 'Key = '.$key . ' ~ Filename = '.$filename.'<br />';
}
$dirItr = $filterItr = $recItr = null;
Supporting class
class DirFileFilter extends RecursiveFilterIterator{
protected $exclude;
protected $root;
protected $mode;
public function __construct( $iterator, $exclude=array(), $root, $mode='all' ){
parent::__construct( $iterator );
$this->exclude = $exclude;
$this->root = $root;
$this->mode = $mode;
}
public function accept(){
$folpath=rtrim( str_replace( $this->root, '', $this->getPathname() ), '\\' );
$ext=strtolower( pathinfo( $this->getFilename(), PATHINFO_EXTENSION ) );
switch( $this->mode ){
case 'all':
return !( in_array( $this->getFilename(), $this->exclude ) or in_array( $folpath, $this->exclude ) or in_array( $ext, $this->exclude ) );
case 'files':
return ( $this->isFile() && ( !in_array( $this->getFilename(), $this->exclude ) or !in_array( $ext, $this->exclude ) ) );
break;
case 'dirs':
case 'folders':
return ( $this->isDir() && !( in_array( $this->getFilename(), $this->exclude ) ) && !in_array( $folpath, $this->exclude ) );
break;
default:
echo 'config error: ' . $this->mode .' is not recognised';
break;
}
return false;
}
public function getChildren(){
return new self( $this->getInnerIterator()->getChildren(), $this->exclude, $this->root, $this->mode );
}
}
