Echo matching key in multidimention array

[Peuplarchie]

Good day to you all,

            I'm working on a piece of code which read a directory recursively and list them as an array.

 

What I'm trying to do here is to echo only the  ones with dir as "dir" as 4th key.

 

Can somebody help me i'm fairly new with arry, specificly multidimensional array.

 

Here is my code :

<?php
   $dir = "Art/";
   function recur_dir($dir)
   {
       $dirlist = opendir($dir);
       while ($file = readdir ($dirlist))
       {
           if ($file != '.' && $file != '..')
           {
               $newpath = $dir.'/'.$file;
               $level = explode('/',$newpath);
               if (is_dir($newpath))
               {
                   $mod_array[] = array(
                           'level'=>count($level)-1,
                           'path'=>$newpath,
                           'name'=>end($level),
                           'kind'=>'dir',
                           'mod_time'=>filemtime($newpath),
                           'content'=>recur_dir($newpath) );
               }else{ 
                   $mod_array[] = array(
                           'level'=>count($level)-1,
                           'path'=>$newpath,
                           'name'=>end($level),
                           'kind'=>'file',
                           'mod_time'=>filemtime($newpath),
                           'size'=>filesize($newpath) );
              }
           }
       }
       closedir($dirlist);
   
   ksort($mod_array);   
       return $mod_array;

$key = array_search('dir', $mod_array);    

   echo '<pre>';
   echo $key;
   echo '</pre>';
   
   }
   

?>

 

Thanks !

sorry i've not tested this but i would do something like:

 

foreach ($mod_array as $key => $array)
{
  if ($array['kind'] == 'dir')
  {
    echo $key;
  }
}

Thanks !

That worked it out !

I understand more, but , here I'm using the array to store a recursive list of files and directories, I can"t seems to only see the file in level 3 let say, can you help me understand that ?

 

foreach ($mod_array as $key => $array)
{
  if ($array['level'] == '2')
  {
    echo $key;
  }
}

 

I can"t make it to work...

Thanks !

sorry I don't understand the question. Could you rephrase it please. What are you trying to achieve and what's the problem?
