Help with readdir and subfolders

PHP
1

Hi All,

I’m trying to write a script to read subfolders in an image directory. This is a bit beyond what I am able to do in php.
In my php code I am trying to read the main directory and then if the loop reads another directory, I am trying to open that and reads its contents as well. I’m not getting any errors per se, but by script in the ‘get subfolders’ portion of the code below is not working. Any suggestions? Thanks in advance.


$dir = '../images/';
// open the current directory
$dhandle = opendir($dir);
// define an array to hold the files
$files = array();
	
if ($dhandle) {
   // loop through all of the files
   while (false !== ($fname = readdir($dhandle))) {
      // if the file is not this file, and does not start with a '.' or '..',
      // then store it for later display
      if (($fname != '.') && ($fname != '..') &&
          ($fname != basename($_SERVER['PHP_SELF']))) {
          // store the filename
          $files[] = (is_dir( "./$fname" )) ? "(Dir) {$fname}" : $fname;
      }
   }
 
//get subfolder contents and file names  
 if (is_dir($fname)) {
	if ($dh = opendir($fname)) {
	while (($file = readdir($dh)) !==false) {
                   echo "filename: $file : filetype: " . filetype($fname . $file) . "\
";
                 }
		closedir($dh);
		}
	}
  
   
 // close the directory
   closedir($dhandle);
}
}

Then I echo out:

// Now loop through the files, echoing out a new select option for each one
foreach( $files as $fname )
{
    echo '<a href="' . $dir . $fname . '"><img src="' . $dir . $fname . '" width="140" height="100"></a>';
}

As long as you are using PHP5 or better, you could use the SPL DirectoryIterator and its cousins.

Here is the first tut that came up which puts SPL DirectoryIterator into context, there are more if you search.

Thanks - yes I’ve been looking at this but not quite sure how to execute it.

or use glob()


function all_files($dir) {
    $files = Array();
    $file_tmp= glob($dir.'*',GLOB_MARK | GLOB_NOSORT);

    foreach($file_tmp as $item){
        if(substr($item,-1)!=DIRECTORY_SEPARATOR)
            $files[] = $item;
        else
            $files = array_merge($files,all_files($item));
    }

    return $files;
}
    
print_r(all_files('../'));

chucks back an array to play with.

I was able to capture the subfolder contents. But now I am having trouble formatting my file path correctly for echoing. I need to echo out a certain structure of the array as given in my php comments - but cannot seem to do this with the array. Any help would be appreciated. Thanks!

$dir = '../images/';
// open the current directory
$dhandle = opendir($dir);
// define an array to hold the files

$files = array();
	
if ($dhandle) {
   // loop through all of the files
   while (false !== ($fname = readdir($dhandle))) {
         // if the element is a directory, and 
         // does not start with a '.' or '..' 
         // passing this element as a parameter
         if (is_dir( "{$dir}/{$fname}" )) {
		 if (($fname != '.') && ($fname != '..')) {
		 if ($dh = opendir( "{$dir}/{$fname}" )) {
		 while (($file = readdir($dh)) !==false) {
			if (($file != '.') && ($file != '..') &&
			($file != basename($_SERVER['PHP_SELF']))) {
			//store subfolder and filename
			//Need structure - $fname/$file for echo
			$files[] = $file;
			}
			}
			closedir($dh);
			}
			}
			}
			}
		closedir($dhandle);
	}

My echo script : I need to include the $fname (path name) in the scr tag, but not sure how to.

// Now loop through the files, echoing out a new select option for each one
foreach( $files as $file )

{
    echo '<img src="' . $dir . $file . '" width="140" height="100"></a>';
}
