php - How to use ::setMaxDepth for RecursiveIteratorIterator? -

i'm using script specify max depth recursive function. don't know how use it, error. how should use ::setmaxdepth here?

public function countfiles($path) {  global $file_count; $depth=0; $ite=new recursivedirectoryiterator($path);  $file_count=0; foreach (new recursiveiteratoriterator($ite) $filename=>$cur) :     $file_count++;     $files[] = $filename; endforeach;  return $file_count; } 

you need call setmaxdepth() on instance of recursiveiteratoriterator. difficult when construct recursiveiteratoriterator within foreach statement. instead, use variable hold it.

$files = new recursiveiteratoriterator($ite); $files->setmaxdepth($depth); foreach ($files $filename => $cur) {     $file_count++;     $files_list[] = $filename; }

however note use of loop not required here (unless code other things have removed in example above). can count of files iterator_count().

function countfiles($path) {     $depth = 1;     $ite   = new recursivedirectoryiterator($path, recursivedirectoryiterator::skip_dots);     $files = new recursiveiteratoriterator($ite);     $files->setmaxdepth($depth);     return iterator_count($files); }
