need help with read dirs and files

[bryson]

Ok... so I have this code which reads all the folders and files within the path

$path = getcwd();
 read_dir($path);
}

function read_dir($dir) { 
   $path = opendir($dir); 
   while (($element = readdir($path)) !== false) { 
     if($element != "." && $element != "..") { 

            if(is_dir($dir."/".$element)) { 
             $dirs[]=$dir."/".$element;   // put all folders in CWD into an array 
             $folders[] = $element;        
            }         
            if(is_file($dir."/".$element)) { 
          $files[]=$element;              // put all files in CWD into an array 
           } 

} 
  } 
   if($dirs) { 
       foreach($dirs as $dir)  echo "$dir<br>"; 
       read_dir($dir);      // call function again to read sub dirs 
  } 

   if($files) { 
        foreach ($files as $file) echo "$file<br>"; 
        } 

closedir($path); 
} 
?> 

this works fine. BUT!
this code will read all the dirs, and if there are sub dirs read them. When there are no more sub dirs, THEN it reads the files.
I want to read a folder and then the files in that folder.
What i'm trying to do:
I have a tree of folders/sub folders with pics. I want to read through them and write the foldername and filename to the database.
So, i think to do this i need to read the folder and then the files in it right after.
INSERT foldername,filename into table
I need the correct folder variable when reading the files.

so if you don't want to read subdirs, then commenting out one line should do it like this:

<?php
function read_dir($dir) {
  $path = opendir($dir);
  while (($element = readdir($path)) !== false) {
    if($element != "." && $element != "..") {

  if(is_dir($dir."/".$element)) {
    $dirs[]=$dir."/".$element;  // put all folders in CWD into an array
    // this doesn't do anything...why is it here??
    $folders[] = $element;
  }
  if(is_file($dir."/".$element)) {
    $files[]=$element;  // put all files in CWD into an array
  }

}
  }
  if($dirs) {
    foreach($dirs as $dir)  echo "$dir<br>";
// comment out this line
//    read_dir($dir);  // call function again to read sub dirs
  }

  if($files) {
    foreach ($files as $file) echo "$file<br>";
  }

  closedir($path); 
} // read_dir
?>

I do want to read sub dirs. You're right, it woud be very easy if i didn't

oh and...
$folders[] = $element; was there cause i was trying to isolate the folder name only instead of the whole path, which i still want to do when i write the folder name to the database. I just forgot to take it out.

I want to read all folders, subfolders and files, everything.
I'm just having a hard time associated the folders with the files.

is this your first run in with hierarchical data? what we're talking about here is not just folders and files but folders within folders and files within folders within folders, etc.

you're gonna have to be more specific about what kind of sort order you want for the output. almost anything is possible, you just have to decide what you want. keep in mind the data is something like this:

MAIN FOLDER
  SUBFOLDER0
    file0_0
    file0_1
    file0_2
  SUBFOLDER1
    SUBSUBFOLDER
      file1_0_0
      file1_0_1
      file1_0_2
  SUBFOLDER2
    file2_0
    file2_1
    file2_2
  file0_0 // this is in the main folder
  file0_1 // so is this

ok, that file structure you wrote.
I want to go through that and write the foldername and that folders filenames to the database.

DB_FIELD1                       DB_FIELD2
SUBFOLDER0                       file0_0
SUBFOLDER0                       file0_1
SUBFOLDER0                       file0_2
SUBFOLDER1/SUBSUBFOLDER          file1_0_0
SUBFOLDER1/SUBSUBFOLDER          file1_0_1
SUBFOLDER1/SUBSUBFOLDER          file1_0_2

Right? So that first row... that file is in that folder. The way my code is now, there's no association between the folders and filenames. it's a dump pretty much.

try this? be sure to view the page source because i'm using line breaks rather than <br>

<?php 
function read_dir($dir) { 
  $path = opendir($dir); 
  while (($element = readdir($path)) !== false) { 
    if($element != "." && $element != "..") { 

  if(is_dir($dir."/".$element)) { 
    $dirs[]=$dir."/".$element;  // put all folders in CWD into an array 
  } 
  if(is_file($dir."/".$element)) { 
    $files[]=$dir . "/" . $element;  // put all files in CWD into an array 
  } 

} 
  } 
  if($dirs) { 
    foreach($dirs as $dir) {
      // comment out this line 
//      echo "$dir<br>"; 
      read_dir($dir);  // call function again to read sub dirs 
    }
  } 

  if($files) { 
    foreach ($files as $file) {
		  $file_parts = explode("/", $file);
			$just_file = array_pop($file_parts);
			$just_dir = implode("/", $file_parts);
		  echo "INSERT INTO mytable SET dir='$just_dir', file='$just_file'\n"; 
    } // foreach file
  } 

  closedir($path); 
} // read_dir 
read_dir(".");
?>

Are you using PHP 5 perchance? Because this problem is much easier to solve with iterators.
