Deleting a File using php/codeigniter

Question

I would like to delete a file that is found in my localhost.

localhost/project/folder/file_to_delete

I\'m using codeigniter for this.

Answer 1

Try this, this works for me:

unlink("./path/to/folder/file_name_do_delete");

for example: I put my file inside uploads folder which is outside the application folder and my file name is 123.jpg. So it should be like this:

unlink("./uploads/123.jpg");

Answer 2

$file = "test.txt";
if (!unlink($file))
  {
  echo ("Error deleting $file");
  }
else
  {
  echo ("Deleted $file");
  }

Answer 3

you can use the "file helper" in codeigniter.

CodeIgniter v3: http://codeigniter.com/userguide3/helpers/file_helper.html#delete_files

CodeIgniter v4: http://codeigniter.com/user_guide/helpers/filesystem_helper.html#delete_files

and like this :

$this->load->helper("file");
delete_files($path);

Late Edit: delete_filesmethod uses a path to wipe out all of its contents via unlink() and same you can do within CI. Like this:

unlink($path); 

a valid path.
