[RESOLVED] stat() doesn't pull any info from files

[NathanaelCulver]

There must be a simple answer to this, but I'm a noob so go easy on me :-)

While trying to write a simple routine that displays the contents of a directory,
something like:

    while (($file = readdir($dh)) !== false) {
      if ( is_dir($file)) echo "d";
      if (!is_dir($file)) echo "f";
      echo ": $file<br>";
    }

I found I couldn't get the routine to recognize a directory entry. So I started playing around with $stat(), and discovered I couldn't pull out stats on any file (except for . and ..). I don't understand why.

I'm running under a locally-installed LAMP: Ubuntu 10.4, ext3, latest Apache2 2.2.14-5ubuntu8 (amd64), PHP 5.3.2-1ubuntu4.

The directory:

nathanael@nathanael-laptop:~/www/accardi/canon/AMFV$ ls -l -a
total 104
drwxr-xr-x  5 nathanael nathanael  4096 2010-05-05 10:23 .

drwxr-xr-x  3 nathanael nathanael  4096 2010-05-05 10:23 Greybox

The code:

clearstatcache();
  if ($dh = opendir($dir)) {
    while (($file = readdir($dh)) !== false) {
      echo "<b>$file</b> - ";
      $stat = stat($file);
      if (!$stat): 
        echo "No stats";
       else:
        for ($i = 0; $i < 13; $i++) { echo $i . ") " . $stat[$i]. " "; }
      endif;
      echo "<br>"; } // end while
    closedir($dh); } // end if ($dh)

The output:

How about including the directory?

$stat = stat($dir.'/'.$file);

That works!

Anyone care to explain to me why?

Thanks.

Because PHP can't read your mind? stat() expects a path to a file... thus you're not actually passing it a filename but a relative path, and a path like "myfile.txt" means "look in the current directory for a file named 'myfile.txt'".

Another way to approach it using [man]glob/man, just for comparison's sake:

$files = glob($dir.'/*');
foreach($files as $file)
{
   $name = basename($file);
   $stats = stat($file);
   // output $name and desired $stat elements
}

Ah, I SEE! Sheesh - I must've stared at my code for two hours thinking, "It's finding the files so it can't be a path issue." But readdir() was finding the files -- then passing an unpathed filename to stat(), which couldn't. Argh!

Thanks for your help.
