directory tree

[slimboy007]

how can i get a list of filename and filepaths with the extension '.png' in the following directory structure, advanced solution should allow further files and directories to be added at any point in the tree:

/*

- folder

  - test1.png

  - test2.png

  - untitled.txt

  - subfolder

    - test3.png

    - untitled1.txt

*/

Below is the recursive function. Please note it can be memory overhead. 

 

this is only to get the filename you can modify it for the filepath also.

 

function getDirectoryTree( $outerDir ){
    $dirs = array_diff( scandir( $outerDir ), Array( ".", ".." ) );
    $dir_array = Array();
    foreach( $dirs as $d ){
        if( is_dir($outerDir."/".$d) ) $dir_array[ $d ] = getDirectoryTree( $outerDir."/".$d );
        else{
		$path_info = pathinfo($d);
		if($path_info['extension'] == 'png'){
			$dir_array[ $d ] = $d;
		}
	}
    }
    return $dir_array;
} 

$dir = getDirectoryTree("C://wamp/www/answers");
echo "<pre>";
print_r($dir);

$iterator = new RecursiveDirectoryIterator( new DirectoryIterator( 'path/to/directory' ) );
while ($iterator->valid()) {
    if ($iterator->isDot()) continue;
    
    echo $iterator->key(), "<br>\n";
}

 

Play with it and modify (extend) to suit your needs.
