Recusive function issues

[gwolgamott]

Having issues setting up my recursion... and too tired apparently to think straight. So bare with me since I think I have a logic issue now. Help I need to find how to make this work recursively. But a brief explanation of what the var are:

$menu_array is an array of the first set of folders in a large directory (see below)

Array ( [0] => Events [1] => Help [2] => Home [3] => Managament Documents [4] => Newsletter ) 

$stopper is used to tell the build_dir function whether or not to return a folder list or just an array with element \[0\] = NULL

$link is a directory list.

$menu_count is just the element count of $menu_array

 

function sort_array($menu_count, $menu_array, $link, $stopper)
{
////////////////////////////////
// $menu_count is number of first set of arrays
// $menu_array is the first set of arrays
// $link is the intial starting location
// $stopper is the stopper file
///////////////////////////////
for($i=0;$i<$menu_count;$i++)
{
	$element = $menu_array[$i];
	$link = "../index/".$element."/";
	$menu_array_2 = build_dir($link, $stopper);

	if ($menu_array_2[0] == NULL)
		{
			echo $link." : ";

			$menu_array_3[$element] = $menu_array_2;
			print_r ($menu_array_2); echo "<br>";
			//echo "NULL"; // for testing only
		}
	if ($menu_array_2[0]!= NULL)
		{
			echo $link." : ";
			print_r ($menu_array_2); echo "<br>";
/////////////////////////////////////THE LINE BELOW IS WHAT I NEED TO TRY TO WORK///////////////
			//$menu_array_3[$element] = sort_array($menu_count, $menu_array, $link, $stopper);
		}	
	$menu_array_2 = array(); // destroys temp array
	}
print_r($menu_array_3); echo "<br>";
return $menu_array_3;
}

gives the current Test output of at the moment:

../index/Events/ : Array ( [0] => New Folder ) 
../index/Help/ : Array ( [0] => ) 
../index/Home/ : Array ( [0] => ) 
../index/Managament Documents/ : Array ( [0] => Engineering [1] => Lateral [2] => Pedestal [3] => Random [4] => Shipping & Recieving ) 
../index/Newsletter/ : Array ( [0] => ) 
Array ( [Help] => Array ( [0] => ) [Home] => Array ( [0] => ) [Newsletter] => Array ( [0] => ) ) 

 

and my build_dir function if want to know what that is:

<?php
function build_dir($cdir,$stopper)
{
$cdir = $cdir;
$stopper = $stopper;
//echo $cdir."<br>";
   $dh=opendir($cdir);
   $dir=array();

while($file=readdir($dh))
   { 
      if(substr($file,0,1)=='.') continue; // if directory/file is . (self), .. (parent) .Filename (hidden). Ignore and continue
      if(is_dir($cdir.$file))
      {
      	$dir[]=$file;
      }
      else
      {
      	if($file == "struct.php")	
      	{
   			//echo $file."<br>";
   			$dir = array(); //DESTROY THE ARRAY IF THERE IS EVER A STRUCT FILE IN THE DIRECTORY
   			$dir[0] = NULL;
   			break;
   		}
   	  }
}
   return $dir;
}
?>

slight infinite loop typo I know I did make...

 

//$menu_array_3[$element] = sort_array($menu_count, $menu_array, $link, $stopper);

 

that line supposed to be something like

 

$menu_array_3[$element] = sort_array($menu_count, $menu_array_2, $link, $stopper);

 

but that is still not right and have myself lost

I solved it... not sure wth I was thinking but just retrofitted a tree travesal file to make need of what I wanted... I'll post the solution I made myself when it is done if anyone is interested. Sorry and thanks to those that read the posts.
