Hyperlink in PHP

When I run this code it lists the files from the cabinet_layout directory, but my hyperlinks are missing "cabinet_layouts" in the url.

cabinet_layouts is a sub-directory in the root directory.

<?PHP
  //$dir = "/cabinet_layouts/";
  // Change directory
  
  $dir = chdir("cabinet_layouts");
  
  function getFileList($dir)
  {
    // array to hold return value
    $retval = array();

    // add trailing slash if missing
    if(substr($dir, -1) != "/") $dir .= "/";

    // open pointer to directory and read list of files
    $d = @dir($dir) or die("getFileList: Failed opening directory $dir for reading");
    while(false !== ($entry = $d->read())) {
      // skip hidden files
      if($entry[0] == ".") continue;
      if(is_dir("$dir$entry")) {
        $retval[] = array(
          "name" => "$dir$entry/",
          "type" => filetype("$dir$entry"),
          "size" => 0,
          "lastmod" => filemtime("$dir$entry")
        );
      } elseif(is_readable("$dir$entry")) {
        $retval[] = array(
          "name" => "$dir$entry",
          "type" => mime_content_type("$dir$entry"),
          "size" => filesize("$dir$entry"),
          "lastmod" => filemtime("$dir$entry")
        );
      }
    }
    $d->close();

    return $retval;
  }
?>

<h1>List PDF files with links</h1>

<table class="collapse" border="1">
<thead>
<tr><th>Name</th><th>Type</th><th>Size</th><th>Last Modified</th></tr>
</thead>
<tbody>
<?PHP
  $dirlist = getFileList("./");
  foreach($dirlist as $file) {
    if($file['type'] != "application/pdf") continue;
    echo "<tr>\n";
    echo "<td><a href=\"{$file['name']}\">",basename($file['name']),"</a></td>\n";
    echo "<td>{$file['type']}</td>\n";
    echo "<td>{$file['size']}</td>\n";
    echo "<td>",date('r', $file['lastmod']),"</td>\n";
    echo "</tr>\n";
  }
?>
</tbody>
</table>

You might try something like this.  For obvious reasons I am not going to leave it on my server, but feel free to copy it and install it for your own use.

<?php // demo/temp_mfinocc.php
error_reporting(E_ALL);

// PUT THIS SCRIPT IN THE WEB ROOT OR OTHER TOP-LEVEL DIRECTORY
$path = realpath(getcwd()) . DIRECTORY_SEPARATOR;

// DEFINE THE FILE NAME SUFFIX YOU WANT TO USE.  DEFAULT: PDF
$suf = !empty($_GET['q']) ? trim($_GET['q']) : 'pdf';
$suf = '.' . $suf;

// CREATE THE REGULAR EXPRESSION TO MATCH THE FILE NAME SUFFIX
$rgx
= '#'              // REGEX DELIMITER
. preg_quote($suf) // THE SUFFIX
. '$'              // AT THE END OF STRING
. '#'              // REGEX DELIMITER
. 'i'              // FLAG FOR CASE-INSENSITIVE
;

// SEE http://php.net/manual/en/class.recursivedirectoryiterator.php#85805
$objs = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);

// UNFORTUNATELY THIS DOES NOT WORK AT PHP 5.4
// var_dump($objs);

// ITERATE OVER THE OBJECTS
foreach($objs as $name => $obj)
{
    // SKIP FILES THAT DO NOT MATCH OUR OBJECTIVE
    if (!preg_match($rgx, $name)) continue;

    // CONSTRUCT A LINK
    $name = str_replace($path, NULL, $name);
    $url
    = '<a target="_blank" '
    . 'href="'
    . $name
    . '">'
    . $name
    . '</a>'
    ;
    echo PHP_EOL . '<br>' . $url;
}
