PHP Not Showing System Files/MAC Files - php

Question

I have a php script that uploads a zip file of images to a folder. This script recursively seeks out only files in the zip file and places all the files in a single directory on the server.
The problem is certain files get double uploaded. This is not the script's fault, but rather, due to the ridiculousness and inferiority of apple computers, when a mac creates a zip file of images it creates a folder of the images and then another folder with the exact same images only it places "._" in front of the file names. So seeing as how we're not going to be blessed with the disappearance of apple computers anytime soon, I tried to include in my php script a simple function to search for these inferior mac abominations and delete them from the directory. However, php isn't even pulling these files when I use "ftp_nlist".
So my question is: How do I get php to pull these stupid things so I can delete them?
$contents = ftp_nlist($conn_id, '.');
foreach($contents as $key => $value){
echo $key." => ".$value."<BR>";
if(substr($value, 1, 1) == ".") {
if(ftp_delete($conn_id, $value)) {
echo "Deleting $value<BR>";
}
}
echo "<BR>";
}
exit();
EDIT:
So thanks to Stephane's suggestion I was able to come up with this which works
if($zip->open($_FILES['theFile']['tmp_name']) === TRUE){
for($i = 0; $i < $zip->numFiles; $i++) {
$filename = $zip->getNameIndex($i);
$fileinfo = pathinfo($filename);
copy("zip://".$_FILES['theFile']['tmp_name']."#".$filename, $ezPresenter['currentFolder'].'/'.$fileinfo['basename']);
}
$zip->close();
}else{
exit("Could not upload/extract file");
}
$contents = ftp_rawlist($conn_id, '-a');
foreach($contents as $key => $value){
$value = explode(" ", $value);
$value = $value[count($value)-1];
echo $key." => ".$value."<BR>";
if(strpos($value, ".") === false) {
if(ftp_delete($conn_id, $value)) {
echo "Deleting $value<BR>";
}
}
if(substr($value, 0, 2) == "._") {
if(ftp_delete($conn_id, $value)) {
echo "Deleting $value<BR>";
}
}elseif(substr($value, 0, 1) == "." && $value != "." && $value != "..") {
if(ftp_delete($conn_id, $value)) {
echo "Deleting $value<BR>";
}
}
}

Answer 1

Use ftp_rawlist instead.
ftp_rawlist — Returns a detailed list of files in the given directory
ftp_rawlist($connid, "-a");
Argument -a means all as on unix command-line: ls -a.

Answer 2

I ran into this issue before, but I wasn't using ftp_nlist. What I ended up doing was using PHP's ZipArchive to open the zip file and look for (and exclude) the __MACOSX directory. I also ignored zip files where just one directory was inside (so you don't unzip the file and then have two directories deep to get to the data - that always annoys me).
My solution may not be the best for you, as it takes some extra processing, but it worked for me :)
Anyway, without further ado... here is the code I am using. Hopefully it'll be of help to you:
//
// unzip the file
$zip = new ZipArchive;
if ($zip->open($fname) === TRUE) {
//extract zip
$zip->extractTo($dir);
$zip->close();
//detect single dir
$basedir = function($x) use (&$basedir) {
$files = glob($x.'*', GLOB_MARK);
//ignore stupid mac directory
$k = array_search($x.'__MACOSX/',$files);
if($k!==FALSE) {
unset($files[$k]);
$files = array_values($files);
}
if(sizeof($files)==1 && is_dir($files[0]))
return $basedir($files[0]);
return $x;
};
//get root directory that has files in it
$dir = substr($basedir($dir.'/'),0,-1);
//
// here I re-zipped the data from the base directory
// and uploaded this file
//
} else {
//delete the file
unlink($fname);
//
// some other error handling
//
return;
}
