Strange problem with opendir()

mdrisser

Hi all,

I'm having a problem with opendir() that I just cannot figure out.

Here's what I'm having problems with:

$galleryDir = "images/projects";

$dh = opendir($galleryDir) or die("Unable to open main gallery directory for reading.");
while($dir = readdir($dh)) {
    //..........
}

Regardless of what I set $galleryDir to, PHP opens the directory the script resides in. The path in $galleryDir above is relative to the script's location.

I've tried using absolute paths, different paths, chdir(), placing the string within the opendir() function rather than the variable, and all I get is the contents of the directory in which the script resides.

I am completely baffled by this one, any help would be greatly appreciated.

FYI:
OS: Windows XP Pro
XAMPP for Windows Version 1.6.6 which has:
PHP: 5.2.5
Apache: 2.2.8

Try something like this:

$galleryDir = "images/projects";

if(is_dir($galleryDir)){
     if($dh = opendir($galleryDir)){
          while($file = readdir($dh) !== false){
               echo "filename: ".$file. "\n";
          }

      closedir($dh);
 }
}

Unfortunately that didn't work either.

I've even tried this, with the exact same results, on 2 different servers 😕 :

$galleryDir = dir('./images/projects');
while($dir = $galleryDir->read()) {
	// Make sure what we're looking at is a directory
	if(is_dir($dir)) {
		// Make sure we're not looking at . or ..
		if($dir != '.' || $dir != '..') {
			echo("DIR: ".$dir."<br />");
			// Open the subdir for reading
			$dir2 = dir($dir);
			// Read the files in the dir
			while($file1 = $dir2->read()) {
				if(is_file($file1)) {
					echo("FILE: ".$file1."<br />");
					// If we're looking at a file and it is description.txt
					if($file1 == 'description.txt') {
						// Read the contents of the file into an array
						$file = file('description.txt');
					} else {
						// Otherwise manually assign to our file array
						$file[0] = "No title";
						$file[1] = "No Description";
					}
				}
			}
			// We're done with this subdir, so close it
			$dir2->close();
			// Assign the results to our multidimesnional array
			$galleries[] = array('Title'=>$file[0], 'Desc'=>$file[1]);
		}
	}
}

The echo("File: ".$file1."<br />") line show, even when I should be 2 levels down, that I'm looking at the same directory the script is in.:bemused:

try this,

$galleryDir = "images/projects";

if(is_dir($galleryDir)){
     if($dh = opendir($galleryDir)){

      while(false !== ($file = readdir($dh))){
           echo "filename: ".$file. "\n";
      }

      closedir($dh);
 }
}
