    This handy little function will, given a starting directory, return an array of directories contained within the original directory. It does this by using recursion, a process by which a function calls itself repeatadly, until all conditions are met. Syntax is Array RecurseDir (string starting_directory)

    By : kuzb

    <?php
    function RecurseDir($basedir, $AllDirectories=array()) {
    #Create array for current directories contents
    $ThisDir=array();
    #switch to the directory we wish to scan
    chdir($basedir);
    $current=getcwd();
    #open current directory for reading
    $handle=opendir(".");
    while ($file = readdir($handle)) {
    #Don't add special directories '..' or '.' to the list
    if (($file!='..') & ($file!='.')) {
    if (is_dir($file)) {
    #build an array of contents for this directory
    array_push($ThisDir,$current.'/'.$file);
    }
    }
    }
    closedir($handle);
    #Loop through each directory, run RecurseDir function on each one
    foreach ($ThisDir as $key=>$var) {
    array_push($AllDirectories, $var);
    $AllDirectories=RecurseDir($var, $AllDirectories);
    }
    #make sure we go back to our origin
    chdir($basedir);
    return $AllDirectories;
    }
    ?>
    /* example */
    <?
    $dirlist=RecurseDir("/home/ben");
    foreach ($dirlist as $key=>$val) {
    echo $val;
    }
    ?>
