Recursive Directory Listing With PHP

Use the following function to list the contents of one or more nested directories.

function recursive_directory($dirname,$maxdepth=10, $depth=0){


 if ($depth >= $maxdepth) {


  return false;


 }


 $subdirectories = array();


 $files = array();


 if (is_dir($dirname) && is_readable($dirname)) {


  $d = dir($dirname);


  while (false !== ($f = $d->read())) {


   $file = $d->path.'/'.$f;


   // skip . and ..


   if (('.'==$f) || ('..'==$f)) {


    continue;


   };


   if (is_dir($dirname.'/'.$f)) {


    array_push($subdirectories,$dirname.'/'.$f);


   } else {


    array_push($files,$dirname.'/'.$f);


   };


  };


  $d->close();


  foreach ($subdirectories as $subdirectory) {


    $files = array_merge($files, recursive_directory($subdirectory, $maxdepth, $depth+1));


  };


 }


 return $files;


}

Use this in the following way.

$files = recursive_directory('folder');


print_r($files); // print the result...

The maximum depth that the function will travel down is set to 10 as a default. This can be overwritten at runtime.

$files = recursive_directory('folder', 20); // make maximum level 20


print_r($files); // print the result...
