Function 2, only deletes files in the specified directory, not the directory folder.

  2. /**
  3. * Loop all files in the directory
  4. * @func delFileUnderDir
  5. * @param $dirName
  6. * @edit bbs.it-home.org
  7. */
  8. function delFileUnderDir( $dirName )
  9. {
  10. if ( $handle = opendir( "$dirName" ) ) {
  11. while ( false !== ( $item = readdir( $handle ) ) ) {
  12. if ( $item != "." && $item != ".." ) {
  13. if ( is_dir( "$dirName/$item" ) ) {
  14. delFileUnderDir( "$dirName/$item" );
  15. } else {
  16. if( unlink( "$dirName/$item" ) ) echo "File deleted successfully: $dirName/$item
  17. n";
  18. }
  19. }
  20. }
  21. closedir ( $handle );
  22. }
  23. }
  24. ?>
Copy the code

Let’s look at the specific calling example. 1. Delete a sibling directory named "upload", that is, all files in this directory:

  2. delDirAndFile( 'upload');
  3. ?>
Copy code

2, delete all files in a directory named "upload" (but there is no need to delete the directory file folder):

  2. delFileUnderDir( 'upload');
  3. ?>
Copy code
