Recursive Directory Listing (Show full directory structure)

[missing-score]

This function will read the full structure of a directory. It's recursive becuase it doesn't stop with the one directory, it just keeps going through all of the directories in the folder you specify.

PHP Code:

<?php

function getDirectory( $path = '.', $level = 0 ){

    $ignore = array( 'cgi-bin', '.', '..' );
    // Directories to ignore when listing output. Many hosts
    // will deny PHP access to the cgi-bin.

    $dh = @opendir( $path );
    // Open the directory to the handle $dh
    
    while( false !== ( $file = readdir( $dh ) ) ){
    // Loop through the directory
    
        if( !in_array( $file, $ignore ) ){
        // Check that this file is not to be ignored
            
            $spaces = str_repeat( '&nbsp;', ( $level * 4 ) );
            // Just to add spacing to the list, to better
            // show the directory tree.
            
            if( is_dir( "$path/$file" ) ){
            // Its a directory, so we need to keep reading down...
            
                echo "<strong>$spaces $file</strong><br />";
                getDirectory( "$path/$file", ($level+1) );
                // Re-call this same function but on a new directory.
                // this is what makes function recursive.
            
            } else {
            
                echo "$spaces $file<br />";
                // Just print out the filename
            
            }
        
        }
    
    }
    
    closedir( $dh );
    // Close the directory handle

}

?>

Example Calls:

PHP Code:

getDirectory( "." );
// Get the current directory

getDirectory( "./files/includes" );
// Get contents of the "files/includes" folder

Thanks man. I didn't want to spend the time writing and thinking about doing this. Helped alot with this little snippet ^^ Thanks again

[thedonkdonk]

I also wanted to say thanks a lot. This is exactly what I was looking for.

[cookieboi]

sorry but this doesn't work on my php server.. I NEED HELP lol.. if i want to show a directory /public_html/flash/ what do i have to put? and what is the "level" variable about??
thanx.

Jamez.

[cookieboi]

ok peeps, soz to double post, just solved it - you need the full directory path including this /home/user/public/foldername/

thanx.

Jamez.

[marek_mar]

This function does the same thing but is a _LOT_ faster:

PHP Code:

function get_dir_iterative($dir = '.', $exclude = array( 'cgi-bin', '.', '..' ))
{
    $exclude = array_flip($exclude);
    if(!is_dir($dir))
    {
        return;
    }
    
    $dh = opendir($dir);
    
    if(!$dh)
    {
        return;
    }

    $stack = array($dh);
    $level = 0;

    while(count($stack))
    {
        if(false !== ( $file = readdir( $stack[0] ) ) )
        {
            if(!isset($exclude[$file]))
            {
                print str_repeat(' ', $level * 4);
                if(is_dir($dir . '/' . $file))
                {
                    $dh = opendir($file . '/' . $dir);
                    if($dh)
                    {
                        print "<strong>$file</strong><br />\n";
                        array_unshift($stack, $dh);
                        ++$level;
                    }
                }
                else 
                {
                    
                    print "$file<br />\n";
                }
            }
        }
        else 
        {
            closedir(array_shift($stack));
            --$level;
        }
    }
} 


[Peuplarchie]

Both code don't work for me, I only see a blank page.

Can someone help ?

[Yaggles]

Peuplarchie, did you actually call the function or did you just copy/paste the code from above into your php page? Because you have to include the above code in <?PHP and ?> and then actually call it inside the php tags like so:

PHP Code:

<?
//Function code
//....

//Now call it by using one of these,
//depending on which function you chose above:
getdirectory('.');
//or
get_dir_iterative(/*etc.*/);
?>

[Eamonnca1]

marek_mar, Dude, that code is lightening fast but I'm finding it only goes two levels deep.

[zz_james]

Not being sniffy, should probably rewrite/repost myself: but the function is both getting the directory listing and printing the result, would be nice if it returned the data from the recursive directory scan (probably in an array) so programmer can specify how it is shown, either print or send to HTML template etc. keep functions doing one thing, getting data from filesystem or printing the result makes it more re-usable.

[Octovir]

PHP Code:

<?
function getDirectory($path = '.', $ignore = '') {
    $dirTree = array ();
    $dirTreeTemp = array ();
    $ignore[] = '.';
    $ignore[] = '..';

    $dh = @opendir($path);

    while (false !== ($file = readdir($dh))) {

        if (!in_array($file, $ignore)) {
            if (!is_dir("$path/$file")) {
                
                $dirTree["$path"][] = $file;
                
            } else {
                
                $dirTreeTemp = getDirectory("$path/$file", $ignore);
                if (is_array($dirTreeTemp))$dirTree = array_merge($dirTree, $dirTreeTemp);
            }
        }
    }
    closedir($dh);
    
    return $dirTree;
}

$ignore = array('.htaccess', 'error_log', 'cgi-bin', 'php.ini', '.ftpquota');

$dirTree = getDirectory('/your/path/here', $ignore);
?>
<pre>
    <?
    print_r($dirTree);
    ?>
</pre>

Not Sure if it's the best, and likely is not, but I modified the first function to get things working for now. This returns an array so that when i go back through the array, I can concatenate my keys with my values for use with something like fopen...

[joelbrock]

The getDirectory function is totally awesome! and exactly what i needed. here's the thing tho: when i was hacking it up on my dev box it was working great. but then, once i got it the way i wanted it, i uploaded the files to the web server, and now everything is coming up in random order.

is there a way to force it to read alphabetically? Is is my web server? is it something else entirely? anybody know of this issue?

TIA

Hi,

This script works pretty well except that the files list is not ordered. I'd like to sort it alphabetically. Any idea how to do that?

For example, I got this:

0012.jpg
0011.pdf
0024.pdf
0004.jpg
0018.pdf
0008.pdf

While I'd like to get this:

0004.jpg
0008.pdf
0011.pdf
0012.jpg
0018.pdf
0024.pdf

Thanks for any help.
