reading list of files

jpr

Hey, I'm trying to figure out how to read in a list of all files in a top level directory, including all files in the subdirectories. I dont want to include direcotrys in my lise, but i want to search them. After looking at php.net, I came up with this, but I got this error:

Warning: readdir(): supplied argument is not a valid Directory resource in /home/jrottman/public_html/sitesearch/admin.php on line 179

Is my code wrong or is that because of file permissions?
Thank you!

Code:

function direcho($path) {
if ($handle = opendir($path)) {
while (false !== ($file = readdir($path))) {
if ($file != "." && $file != "..") {
if (is_dir($file)) {
direcho($path.$file);
} else {
echo $file . "<br>\n";
}
}
}
}
}

direcho("/home/jrottman/public_html/");

Your readdir should reference your opendir handle

while($file = readdir($handle))

Thanks, it works now, it reads in all the files in all directorys. However it still shows the directory name. Any idea how to get around this? Thank you.

function direcho($path) {
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
if (is_dir($file)) {
direcho($path.$file);
} else {
echo $file . "<br>\n";
}
}
}
}
}

direcho("/home/jrottman/public_html/");

use either is_file() or is_dir() to see what's what.

Instead of echo'ing the list of files, what would be the best way to just put the list in an array? Also I've tried just adding one more check right before I echo the file name, I tried using

if(is_file($file))

However that just screws up the list, nothign shows up then.
Thank you for your help.

See, this is why I never get things done. You guys get me thinking about things, playing with these scripts, hours go by, I completely lose track of time.

But I digress.

Anyway, played with it for a while, had tons of trouble with accuratly recursing though the directories, but got this to work for me. Someone else can prolly do it better, but oh well. I like figuring things out.

function direcho($path,$array) {
   $dir    = array();
   $handle = opendir($path);
   while($file = readdir($handle)) {
      if($file != "." && $file != "..") {
         if(!is_dir($file)) {
            $array[] = $file;
         }
         else {
            $dir[] = $path.$file."/";
         }
      }
   }
   closedir($handle);
   foreach($dir as $d) {
      $arr   = array();
      $new   = direcho($d,$arr);
      $array = array_merge($array,$new);
   }
   return $array;
}

$files = direcho("/path/to/your/dir/",array());
echo "<pre>";
print_r($files);
echo "</pre>";
?>
