Question

I am using a php scan directory script that will scan the contents of a directory and then populate the page with links to the directory contents.

<?php
$count = 0;
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
    if ($file != "." && $file != "..") {$count++;
        print("<a href=\"".$file."\">".$file."</a><br />\n");
    }
}
echo '<br /><br /><a href="..">Return</a>';
closedir($handle);
}
?

I am wondering how I can exclude certain files or file types like test.xml, durka.xslt or .html from showing up on the populated page. I have some code but not sure how to integrate it. Any help would be very appreciated…

?php
if ($handle = opendir(‘.’)) {
while (false !== ($file = readdir($handle)))
{
if ($file != “.” && $file != “..”
&& $file != “NOT-TO-BE-IN-1.php”
&& $file != “NOT-TO-BE-IN-2.html”
&& $file != “NOT-TO-BE-IN-3.jpg”
&& $file != “”
&& $file != “”
&& $file != “”
&& $file != “”
&& $file != “”

<?php

  // These files will be ignored
  $excludedFiles = array (
    'excludeMe.file',
    'excludeMeAs.well'
  );

  // These file extensions will be ignored
  $excludedExtensions = array (
    'html',
    'htm',
    'php'
  );

  // Make sure we ignore . and ..
  $excludedFiles = array_merge($excludedFiles,array('.','..')); 

  // Convert to lower case so we are not case-sensitive
  for ($i = 0; isset($excludedFiles[$i]); $i++) $excludedFiles[$i] = strtolower(ltrim($excludedFiles[$i],'.'));
  for ($i = 0; isset($excludedExtensions[$i]); $i++) $excludedExtensions[$i] = strtolower($excludedExtensions[$i]);

  // Loop through directory
  $count = 0;
  if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
      $extn = explode('.',$file);
      $extn = array_pop($extn);
      // Only echo links for files that don't match our rules
      if (!in_array(strtolower($file),$excludedFiles) && !in_array(strtolower($extn),$excludedExtensions)) {
        $count++;
        print("<a href=\"".$file."\">".$file."</a><br />\n");
      }
    }
    echo '<br /><br /><a href="..">Return</a>';
    closedir($handle);
  }
