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 !

It's not really clear what you want. Your script defines a function which it does not call. You are also randomly using array_search. You need to be more clear.

My goal is to diplay only the arrays that has "Dir" as kind :

 $mod_array[] = array(
                       'level'=>count($level)-1,
                       'path'=>$newpath,
                       'name'=>end($level),
                       'kind'=>'dir',
                       'mod_time'=>filemtime($newpath),
                       'content'=>recur_dir($newpath) );

OK so if the function already works (does it?) then you just need to comment out the else part of your function:

}else{
//                   $mod_array[] = array(
//                           'level'=>count($level)-1,
//                           'path'=>$newpath,
//                           'name'=>end($level),
//                           'kind'=>'file',
//                           'mod_time'=>filemtime($newpath),
//                           'size'=>filesize($newpath) );
              }

Actually, the key is 'kind' 🙂

       

   ksort($mod_array);   

       return $mod_array;

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

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

   }

Well, the ksort() won't achieve anything, because it's sorting the keys of $mod_array - which are all numeric.
And everything after the [font=monospace]return[/font] will of course be missed because it's after the return. So I'll assume that it's an example of how the results of the function will be used, that the '}' is misplaced, and that there is a "$mod_array = recur_dir('Art/');" line somewhere.

Your array_search will not find anything in $mod_array because none of its elements is the string "dir". The elements of the elements of $mod_array might equal that string.

$mod_array = recur_dir('Art/');

You want to find all the elements in $mod_array that contain an element with a value of 'dir'. (I say "all" even though array_search would only return one, but if you have all of them you're free to pick whichever one you want).

$dirs = array()
foreach($mod_array as $entry)
{
	if($entry['kind']=='dir')
		$dirs[] = $entry;
}

print_r($dirs);

You could, if you wanted to be witty, put that test in a function and use it as a filter.

function is_a_directory($entry)
{
	return $entry['kind']=='dir';
}

$dirs = array_filter($mod_array, 'is_a_directory');

All of which is assuming you might want the files as well for something. Otherwise, as sneakyimp suggests, if you only want directories, don't include non-directories in your results.
