Why isn't this working?

[Trid3nt]

I've written a script that searches a given directory and finds all the text files in it. Each of my users has a Profile that is stored in their own text file. I circulate through the directory, take information from each file, and post it. I am getting an error that reads like this: "Warning: Supplied argument is not a valid Directory resource in [directory]cr3w.php on line 19"

I had a code savvy friend look it over and it looks fine... not sure what is up.

<?PHP
	$dir = "/Volumes/Portfolio/jamesm/Sites/passwords/profiles"; 
	while ($textfile = readdir($dir)) {
		if($textfile != "WS_FTP.LOG"){
			if (!is_dir($textfile)) {
				$profile = file($textfile);
				foreach($profile as $line){
					$line = trim($line);
					$entries = explode("|!!|", $line);
					$name = $entries[0];
					$quote = $entries[2];
					$beverage = $entries[3];
					$info = $entries[4];
					$rig = $entries[5];
					$imagename = str_replace(".txt",".jpg","$textfile");
					echo "<tr><td width=150 valign=top><img src=images/" . $imagename . " width=150></td>";
					echo "<td><b><font color=red>" . $name . "</font></b><br>";
					if ($name == "Trid3nt")
						echo "Position:  Organizer, Network/Tech Support, Webmaster, and Vid Guy<br>";
					if ($name == "J45p3r")
						echo "Position:  Network Admin, Tech Support, Co-Organizer<br>";
					if ($name == "Doram")
						echo "Position:  Security<br>";
					echo "Quote:  \"" . $quote . "\"<br>";
					echo "Favorite LAN Beverage:  " . $beverage . "<br>";
					echo "Info:<br><blockquote><i>\"" . $info . "\"</i></blockquote><br>";
					echo "Rig:  " . $rig . "<br></blockquote><br></td></tr>";
		                }
			}
		}
	}

I advise you to make some debugging. I mean, use the print_r function and other to try find the bug. It's handiwork.

The line that is giving me all the trouble is this one (line 19 in the overall document): while ($textfile = readdir($dir))

That is the one that I'm getting the Warning for.

We know where the problem is, but everything seems to be in order... not sure what is up.

if ($handle = opendir('/path/to/files')) {
    echo "Directory handle: $handle\n";
    echo "Files:\n";

/* This is the correct way to loop over the directory. */
while (false !== ($file = readdir($handle))) { 
    echo "$file\n";
}

/* This is the WRONG way to loop over the directory. */
while ($file = readdir($handle)) { 
    echo "$file\n";
}

closedir($handle); 
}
?>
