Getting PHP to show files and file icons...

[davo666]

hi, what function and regex should i use to get php to take the file extention of a file and show an icon instead -im getting my files from an ftp server

eg

ftp_nlist gives you index.php

i would like to get everything after the . and then use a switch ($extension)

case 1 php

<img source

case 2 etc

i can use stristr but it dosent work with say

aclass.inc.php

or

a folder called

ithas.2.periods

• also how do i tell if its a folder or not .ive heard of metadata, but dont know how to implement it

thanks

(This assumes that the images directory contains file type icons files such as "directory.png", "file.png", "php.png", "html.png", etc.)

DirList.php:

<?php
class DirList
{
   private $dir;
   private $listing;

   public function DirList($dir)
   {
      if(!is_dir($dir))
      {
         user_error("DirList(): '$dir' is not a valid directory");
         return(FALSE);
      }
      $this->dir = $dir;
      $this->buildList();
      uasort($this->listing, array($this, 'SortList'));
   }

   public function getDirName()
   {
      return($this->dir);
   }

   public function getDirList()
   {
      return($this->listing);
   }

   private function buildList()
   {
      $files = glob($this->dir . '/*');
      foreach($files as $file)
      {
         $name = basename($file);
         if(is_dir($file))
         {
            $this->listing[$name] = array(
               'type' => 'directory',
               'size' => ''
            );
         }
         else
         {
            $this->listing[$name]['type'] = $this->getType($file);
            $this->listing[$name]['size'] = filesize($file);
         }
      }
   }

   public function getType($file)
   {
      if(is_dir($file))
      {
         return('directory');
      }
      $parts = explode('.', basename($file));
      return((count($parts) > 1) ? strtolower(array_pop($parts)) : 'file');
   }

   private function sortList($a, $b)
   {
      if($a['type'] == 'directory' and $b['type'] != 'directory')
      {
         return -1;
      }
      elseif($b['type'] == 'directory' and $a['type'] != 'directory')
      {
         return 1;
      }
      else
      {
         return(strcmp($a, $b));
      }
   }
}

Sample usage:

require_once "DirList.php";
$test = new DirList($_SERVER['DOCUMENT_ROOT'].'/test');
$imgDir = $_SERVER['DOCUMENT_ROOT'].'/images/';
echo "<h2>Listing for /test:</h2>\n";
echo "<ul>\n";
foreach($test->getDirList() as $name => $info)
{
   printf(
      "<li><img src='/images/%s' alt='%s'> %s %s</li>\n",
      (file_exists($imgDir.$info['type'].'.png')) ? 
         $info['type'].'.png' :
         'file.png',  // default image
      $info['type'],
      $name,
      ($info['type'] != 'directory') ? "({$info['size']} bytes)" : '' 
   );
}
echo "</ul>\n";

Hello NogDog,

Neat piece of code! But how would I use an icon for folders in that directory? Also, the folder extensions do not work for new MS Office extensions such as xlsx and docx. Am I doing something wrong?

Images in images directory:
Word 2007 - doc.png
Word 2010 - docx.png - Does not recognise
Excel 2007 - xls.png
Excel 2010 - xlsx.png - Does not recognise

Any help and advice would be appreciated 🙂

If I'm reading my code right (it's almost 7 years old!), I think the folder thing could be handled with an image named "directory.png". As for your other questions, I don't know what the problem might be without seeing your code, other than the possibility that it's an upper-/lower-case issues somewhere?

[dalecosp]

Do you actually have an image called "xlsx.png", "docx.png", etc?

[sniper8439]

Thanks for the reply guys!
I've pasted my code below. I have not touched DirList.php. All images are in the server root - "/images/file_ext/". I have created xlsx.png and docx.png in the images/file_ext/ direcrtory. I can't see why this will not work.

<?php

require_once "DirList.php";
$test = new DirList($SERVER['DOCUMENT_ROOT'].'/menus');
$imgDir = $SERVER['DOCUMENT_ROOT'].'/images/file_ext/';
echo "<h2>Listing for /test:</h2>\n";
echo "<ul>\n";
foreach($test->getDirList() as $name => $info)
{
printf(
"<li><img src='/images/%s' alt='%s'> %s %s</li>\n",
(file_exists($imgDir.$info['type'].'.png')) ?

$info['type'].'.png' :
'file.png', // default image
$info['type'],
$name,
($info['type'] != 'directory') ? "({$info['size']} bytes)" : ''

);
}
echo "</ul>\n";

How would I apply directory.png to display as images for all folders in the selected directory?

I notice at the top you define $imgDir to be '/images/file_ext/' however below in the src of the img take you are looking in '/images/' notice the lack of file_ext in the second part. I imagine this is the cause of problems.

Ah, thank you soo much! I can't believe I missed that! It's a very small piece of code, I'm ashamed to call myself a coder!!!!!

Thanks again 🙂
