various php questions pls help

[proto]

1. is there a way to display the directories of a server using php

2. how do you display a little loading thingy while the page loads

thanx in advance

Try a function like this for listing directories and/or files:

function list_files($dir) {
// Returns array of file/directory names from $dir

    $i=0;
    if ($use_dir = @opendir($dir)) {
            while (($file = readdir($use_dir)) !== false) {
                    if ($file != "..") && ($file != ".") {
                        $dir_arr[$i] = "$file";
                        $i++;
                    }
            }
            closedir($use_dir);
    }

    return $dir_arr;

}

As for your second question, you'll probably want to use Javascript, but you won't likely get any Javascript code out of this forum. Try http://javascript.internet.com

i get a parse error

[brad_fears]

Whoops. Change this line:

if ($file != "..") && ($file != ".") {

to this:

if (($file != "..") && ($file != ".")) {

Then it should work.

are you calling the function like this list_files('/');

also this function is not recursive, so here is a modified version:

function listFiles($dir,$level) {

  //set up indenting to the display looks nice.
  $spacer = '';
  for($i=0;$i<$level;4i++) {$spacer = $spacer + '&nbsp;&nbsp;&nbsp;&nbsp;';}

  //open the cirectory or display an error
  if(!$curDir = opendir($dir)) {return 'Could not open directory ($dir)';}

  //loop through all the files in the directory
  while($file = readdir($curDir)) {
     //print out the current file.
     echo "$spacer $file<br>\n";
     //if the current file is a directory call this function again and increase the level of indentation.
     if(is_dir($file) && ($file != '..' && $file != '.')) {
       listFiles($file,($level+1));
     } //end if
  } //end while
} //end listFiles

then call the function like so

listFiles('/');
