php - How to perform a statement inside a query to check existence of a file that has the query id as name with less resources in laravel -


i'm looking away see if query 'id' has folder same id name in file system, did slow down drive in future lots of files

$query = model::all();  if(input::get('field') == 'true'){     $filenames = scandir('img/folders');    $query->wherein('id', $filenames); }

as can see scan , names of folders inside 'folders' directory , create array it, app going have hundreds of thousands of folders in future , resolve before happens, further help

ps: other propositions differently welcome

do have reason believe scandir on directory large number of folders slow down?

you can query this:

if(input::has('field')){     $filenames = scandir('img/folders');     $query = model::wherein('id', $filenames)->get(); }

edit 2

there suggestions in links should able use guidance make own implementation. see it, based on links included first edit made, options use directoryiterator, readdir or chunking scandir.

this basic way of doing guess readdir this:

$ids = model::lists('id');  $matches = [];  if($handle = opendir('path/to/folders')) {     while (($entry = readdir($handle)) !== false)      {         if(count($ids) === 0)         {             break;         }          if ($entry != "." && $entry != "..")          {             foreach ($ids $key => $value)              {                 if($value === $entry)                 {                     $matches[] = $entry;                      unset($ids[$key]);                 }             }         }     }      closedir($handle); }  return $matches;
