Bizarre directory name problem

skiloff

I'm creating a dynamic link to all files in a specific directory so files can just be dropped into that directory and will automatically display on the page at next reload. I have the following code:

$directory = "../pdfs/programs";
$dirHandle = opendir($directory);
echo "<a href='../pdfs/programs/January 2003.pdf'>January 2003 Program</a>";
$nCount = 0;

while ($szFileName = readdir($dirHandle) )
{
                if (is_file($szFileName) )
	{
		$retArray[$nCount++] = $szFileName;

}

}

sort($retArray);

The $directory only works if the directory is "." If I change the directory to anything else, I get a Wrong datatype error on the sort (at the bottom) like its not getting an array. I can change to an non-existant directory and I get the non-existant directory error, so it obviously is recognizing the directory defined in $directory. Notice the echo line below uses the same path and it works just fine. Does anyone have a clue why this won't work??

This is absolutely driving me nuts. I've tried "$DOCUMENT_ROOT/pdfs/programs", "/pdfs/programs", "\pdfs\programs", "\pdfs\programs" and many combinations thereof and it does not work. I'm using windows 2000 with apache.

OK, so I added an echo statement in the while loop as:

while ($szFileName = readdir($dirHandle) )
{
	echo $szFileName;
	if (is_file($szFileName) )
	{
		$retArray[$nCount++] = $szFileName;
	}
}

The echo statement shows the files in the directory, but will not sort them, I get the Wrong datatype in sort() call error, I assume because it doesn't recognize $retArray as an Array?? Any ideas?? Please??? Why does it work with files in the same directory and not with files in another directory?

firstly I'd do a var_dump just to see what's in $retArray, you may need to use ksort()

and for what it's worth here's some code I use


  $handle=opendir('uploads/');

$distNames = ""; 
while (false!==($file = readdir($handle))) 
{  

  if ($file != "." && $file != "..") 
  { 
    $distNames .= "<tr><td align='center'><input type='radio' value='{$file}' name='distFile'></td><td>{$file}</td></tr>"; 
  }     

} 
closedir($handle);

OK, I figured out what was causing it not to work, but not why. It was not evaluating any of the files as files in the if (is_file($szFileName)), thus they were never getting into the array. Why this occurred, I don't know, and why it worked in the "." directory and no others, I don't know. I've removed the file check (I'll just make sure there are no sub directories in that directory - something I never intended anyway) and that has pretty much taken care of it. If anyone knows why it may not have evaluated them as files (they are pdfs) I'd be interested to know. Thanks.
