会递归删除与特定文件扩展名匹配的文件吗？

Question

I would like to delete all files matching a particular extension in a specified directory and all subtree. I suppose I should be using using unlink but some help would be highly appreciated... Thank you!

Answer 1

you need a combination of this

Recursive File Search (PHP)

And the unlink / delete

You should be able to edit the example instead of echoing the file, to delete it

Answer 2

To delete specific extension files from sub directories, you can use the following function. Example:

<?php 
function delete_recursively_($path,$match){
   static $deleted = 0,
   $dsize = 0;
   $dirs = glob($path."*");
   $files = glob($path.$match);
   foreach($files as $file){
      if(is_file($file)){
         $deleted_size += filesize($file);
         unlink($file);
         $deleted++;
      }
   }
   foreach($dirs as $dir){
      if(is_dir($dir)){
         $dir = basename($dir) . "/";
         delete_recursively_($path.$dir,$match);
      }
   }
   return "$deleted files deleted with a total size of $deleted_size bytes";
}
?>

eg To remove all text files you can use it as follows:

<?php echo delete_recursively_('/home/username/directory/', '.txt'); ?>
