Example: Read directory

The follwing directory functions can be used to read the content of a directory.

<?php 
<?v1
/*
    Read the content of current directory and allow to navigate through directories.    
*/

error_reporting (0); // 1 for all errors

dir = "";

do {

  // Change directory
  chdir (dir);
  dir = getcwd (); // Current directory

  dh = opendir (dir);
  if (!dh) {
    print ("Cannot open directory.");
  }
  else {

    fileList = array ();
    // Get list of files / sub directories
    while ((dirEntry = readdir (dh))!==false) {
      array_push (fileList, dirEntry);
    }
    closedir (dh);

    // Show info
    print ("\r\n", dir." ".count(fileList)." entries", "\r\n");

    // Sort the file list (optional)
    sort (fileList);

    // Show the list
    for (z=0;z<2;z++) {
      foreach (fileList as filename) {

        fileTime = filemtime(dir."/".filename);
        if (is_dir (dir."/".filename)) {
          // Show sub directories
          if (z>0)
            continue;
          printf ("%10s %12s %s", "", date ("%M %d %H:%i", fileTime), filename);
        }
        else {
          // Show files
          if (z==0)
            continue;
          printf ("%10s %12s %s", filesize (dir."/".filename), date ("%M %d %H:%i", fileTime), filename);
        }
      }
    }
  }
  do {
    dirNew = input ("\r\nChange directory:");
