deleting all files from a folder on Linux server using PHP - php

Question

My question is almost the same as this one Deleting all files from a folder using PHP?
And I tried to use the answer provided by #Floern https://stackoverflow.com/a/4594262/2167772
But it didn't work for me. I tried to get filenames from a folder on the Linux server. And I have changed the folder and file permission to rwxrwxrwx. And I got the "Unable to get the filename" message all the time. Does anyone know how to solve it? Thanks a lot!
$files=glob('/data/in/*') or die ("Unable to get the filename");
foreach ($files as $file) {
if(is_file($file)){
echo $file;
unlink($file) or die ("Uable to delete file!");
}
}
------Update----
I just figured it out. It is the problem with the server. I cannot write anything to the data folder even I assign the write permission. I will move my in folder to another folder.
Thank you so much for everyone's comments!

Answer 1

As said #Marc B, you just have to write this :
$files=glob('data/in/*') or die ("Unable to get the filenames!");
foreach ($files as $file) {
if(is_file($file)){
echo $file;
unlink($file) or die ("Unable to delete file!");
}
}
You write : glob('/data/in/*'), I write glob('data/in/*')
You use absolute path, i use relative path.

Use this tutorial:
http://de3.php.net/manual/de/function.rmdir.php#107233
And check is your folder permission is enable to write.
Have you trying like this:
$dir = 'your/directory/';
foreach(glob($dir.'*.*') as $v){
unlink($v);
}

if file is not at public directory...
change mode of file to 777
$files=glob('data/in/*') or die ("Unable to get the filename");
foreach ($files as $file) {
if(is_file($file)){
echo $file;
chmod($file,777);
unlink($file) or die ("Uable to delete file!");
}
}

Answer 4

solution with php. don't like the glob function. you can use the RecursiveDirectoryIterator
$filePath = '/someDir';
$directoryIterator = new \RecursiveDirectoryIterator(realpath($filePath));
foreach (new \RecursiveIteratorIterator($directoryIterator) as $object ) {
if(!$object->isDir())
{
unlink($object->getPath());
}
}
