Using the Recursive Directory Listing (Show full directory structure) post, I have amended it slightly to allow a user to fully delete an entire directory recursively, please note this may not work in Safe Mode PHP depending on settings.

PHP Code:
<?php

function remDirectory$path '.'){

    
$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     
            
            
if( is_dir"$path/$file" ) ){
            
// Its a directory, so we need to keep reading down...
            
                
remDirectory"$path/$file");
                
// Re-call this same function but on a new directory.
                // this is what makes function recursive.
            
            
} else {
            
                
unlink("$path/$file");
                
// Just print out the filename
            
            
}
        
        }
    
    }
    
    
closedir$dh );
    
rmdir($dh);
    
// Close the directory handle

}

remDirectory('/home/var/public_html/atest/');

?>

Just incase anyone was wondering if the two could be user together you could probably make a nice combination of the two with a 3rd param which specifies what kind of action the function is performing.

Hope it helps someone!
