List file names

[Hoogs]

I have php creating text files in a specified folder for me but now I want to be able to list all the file names in the folder.

Ultimately I would like to use a search to retrieve file names.
I could do this in flash if I can get the file names into an array but would love to know if there is a better way of doing this.

Are there any tutorials dealing with this?

Thanks.

PHP Code:

$files = array();
$handle = opendir("directory");
while($file == readdir($handle) if($files != "." && $files != "..") $files[] = $file;
closedir($handle);
echo "&files=" . implode("|", $files); 


when that string variable 'files' is loaded into flash, use Array.split() to convert it into an array. i.e.
var file_array:Array = files.split("|");

that should handle the getting all the files into an array for ya ^_^

Nice. Thanks for that.

If you have time, would you be able to explain the

while($file == readdir($handle) if($files != "." && $files != "..") $files[] = $file;

line?

Thanks again.

well, I'm lazy, and I made a bunch of typoes, but that should probably be written as

PHP Code:

while (false !== ($file = readdir($handle))) {
    if($file != "." && $file != "..") {
        $files[] = $file;
    }
} 


notice the corrections, it's important :b

anyway, here's the breakdown : )

1: while (false !== ($file = readdir($handle)))
readdir($handle) returns the next file in the directory -- when there are none left, it evaluates to false and ends the while loop.

2: if($file != "." && $file != "..")
we're just checking here to make sure that the $file isn't . or .. which are both present in every folder and mean 'this folder' and 'parent folder'

3: $files[] = $file
throw the file into the array : )

If you have other directories in that directory it will cause problems -- you'll have to check if it's a directory using is_dir. If you're just looking for a certain kind of file, i.e. text files, replace the if conditional with this:

if (strtolower(substr($file, -4)) == ".txt")

that should hopefully take care of things for you ^_^

Above and beyond the call of duty.

Thanks a ridiculously large amount.

Too much is always better than not enough!

No problem ^^
