file - PHP directory listening with permissions -


i have webpage (apache2) based on linux ubuntu server 14.04 lts (32bit).

i found, according me, , simple php directory/file listener.

my problem is: don't know how show directories/files have 0700 permission. open file. don't want change permissions because on webpage, users have login use website. mean files have 0700 permission not public, , want members of website can use/download files.

my code is: 

<?php     $dirlist = getfilelist("./uf/"); ?> <table border="1"> <thead> <tr><th>name</th><th>type</th><th>size</th><th>last modified</th></tr> </thead> <tbody> <?php         // output file list table rows         foreach($dirlist $file) {         echo "<tr>\n";         echo "<td><a href=\"{$file['name']}\">",basename($file['name']),"</a></td>\n";         echo "<td>{$file['type']}</td>\n";         echo "<td>{$file['size']}</td>\n";         echo "<td>",date('r', $file['lastmod']),"</td>\n";         echo "</tr>\n";     } ?> </tbody> </table> <?php     function getfilelist($dir, $recurse=false)     {         $retval = array();          // add trailing slash if missing         if(substr($dir, -1) != "/") $dir .= "/";          // open pointer directory , read list of files         $d = @dir($dir) or die("getfilelist: failed opening directory $dir reading");         while(false !== ($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$entry")                 );                 if($recurse && is_readable("$dir$entry/")) {                     $retval = array_merge($retval, getfilelist("$dir$entry/", true));                 }             } 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;     } ?>

i hope can understand i'm talking about.
