Dynamically adding dimensions to an array using for loop

[Tanner]

Here is my dilemma and thank you in advance!

 

I am trying to create a variable variable or something of the sort for a dynamic associative array and having a hell of a time figuring out how to do this. I am creating a file explorer so I am using the directories as the keys in the array.

 

Example:

I need to get this so I can assign it values

 

$dir_list['root']['folder1']['folder2'] = value;

 

so I was thinking of doing something along these lines...

 

if ( $handle2 = @opendir( $theDir.'/'.$file ))
{
    $tmp_dir_url = explode($theDir);
    for ( $k = 1; $k < sizeof ( $tmp_dir_url ); $k++ )
    {
        $dir_list [ $dir_array [ sizeof ( $dir_array ) - 1 ] ][$tmp_dir_url[$k]]
    }

 

this is where I get stuck, I need to dynamically append a new dimension to the array durring each iteration through the for loop...but i have NO CLUE how

You have used explode() function, it will require delimiter character, as first parameter in function.

Yeah I know, that was a typo... still isn't going to work...working on something right now though.  crossing fingers

Recursion or maybe array references or both, but this works with just recursion:

 

function dir_tree($dir) {
$files  = glob("$dir/*");

foreach($files as $file) {
	if(is_dir($file)) {
		$result[basename($file)] = dir_tree($file);
	} else {
		$result[] = basename($file);
	}
}
return $result;
}
