PHP: remove filename from path

Question

Say I have an path: images/alphabet/abc/23345.jpg

How do I remove the file at the end from the path? So I end up with: images/aphabet/abc/

Answer 1

You want dirname()

Answer 2

dirname() only gives you the parent folder's name, so dirname() will fail where pathinfo() will not.

For that, you should use pathinfo():

$dirname = pathinfo('images/alphabet/abc/23345.jpg', PATHINFO_DIRNAME); 

The PATHINFO_DIRNAME tells pathinfo to directly return the dirname.

See some examples:

• For path images/alphabet/abc/23345.jpg, both works:

  <?php  $dirname = dirname('images/alphabet/abc/23345.jpg');  // $dirname === 'images/alphabet/abc/'  $dirname = pathinfo('images/alphabet/abc/23345.jpg', PATHINFO_DIRNAME);  // $dirname === 'images/alphabet/abc/' 

• For path images/alphabet/abc/, where dirname fails:

  <?php  $dirname = dirname('images/alphabet/abc/');  // $dirname === 'images/alphabet/'  $dirname = pathinfo('images/alphabet/abc/', PATHINFO_DIRNAME);  // $dirname === 'images/alphabet/abc/'
