How To List Files In A Directory + Subdirectory And Then Use Them.

So lets say i have folders called friends and work in a folder called pics.

how would i make a function that lists the files in those folderscalled images

kinda like this:

CODE

$directory = "./"
function listfiles($directory) {
//here should go the script to list the files in those directories. so that i can continue to work with them. like for example if there were images it would list all the images and i could write a script to make a thumb of them and then save it into a thumb folder(not asking for all of that). but how would i make it list it.

// basicly what i need is a loop for the files and a echo that lists them.
}

the key point in my question is that it repects subdirectories. which is important forthe script i wanna make.

any ideas?

Do you want to "hard-code" the sub-directory names? or have the sub-drectories found by the script in that directory? Makes a difference to the scripting involved.

Is it acceptable that you have to tell the script which sub-diectories to list the contents of?

hm i suppose i could do that myself with an array or? but what i want it to do automaticly. and thats what i cant do.

i want it go through each of the folders where the script is run. and list the files. then look through the subfolders to see if theres any subfolders there ect.

i hope this is not to hard to code. if it only works with one level of subfolders i suppose that would be ok too.

There is a way to do that, and I thought I had a script for it, but I can't seem to find it. I'll keep looking for it. It is a recursive loop that does precisely what you want.

hi, sxyloverboy, I have found this in www.php.net. It should be your need.

CODE

I would like to present these two simple functions for generating a complete directory listing - as I feel the other examples are to restrictive in terms of usage.

function dirTree($dir) {
   $d = dir($dir);
   while (false !== ($entry = $d->read())) {
       if($entry != '.' && $entry != '..' && is_dir($dir.$entry))
           $arDir[$entry] = dirTree($dir.$entry.'/');
   }
   $d->close();
   return $arDir;
}

function printTree($array, $level=0) {
   foreach($array as $key => $value) {
       echo "<div class='dir' style='width: ".($level*20)."px;'> </div>".$key."<br/>\n";
       if(is_array($value))
           printTree($value, $level+1);
   }
}

Usage is as simple as this:
$dir = "<any directory you like>";
$arDirTree = dirTree($dir);
printTree($arDirTree);

It is easy to add files to the tree also - so enjoy.

hm that one dosent really work. it just shows a line called array. and yes i made the directory name right i tried a number of possiblities

/pics/, /pics, ./pics, ./, /, pics/, pics

dont know what else i could try but ive come to the conclusion that this script is faulty
