Deleting “.part” files from folder with PHP

Question

I'm using the following to delete all files from the specified directory.

$files = glob('path/to/temp/*');
foreach($files as $file){
if(is_file($file)) 
unlink($file);
}

It removes everything other than partially uploaded files eg : myfile.mp3.part

I've tried specifying .part in the file path just to see if I can force it that way :

$files = glob('path/to/temp/*.part');

But that doesn't work either. Am I missing something here? Is there a different method for deleting non-active partial files?

Answer 1

$files = scandir('/path/to/temp');

foreach($files as $key => $file) {
    if ( preg_match('/.*?\.part$/', $file) ) {
        unlink($file);
    }
}

Answer 2

I'm using something likes this to delete all files in a folder.

$dir = "/path/to/temp";
$files = scandir($dir);
foreach($files as $file){
    $path = $dir."/".$file;
    if(is_file($path)) unlink($path);
}
