Different ways to use the glob() function to delete files

  1. Delete files with .css extension
  2. Delete files that start with ‘spec-’ name

1. Delete files with .css extension

As we discussed, here we will use the glob() function to get a list of the file names from a folder which contains the .css extension.

delete-css-files.php

In the above code, we used the is_file() function to check if a file exists or not. This will help us to filter only files not directories.

Also we used the unlink() function to delete the files from a folder.

That’s it to delete all .css files from a folder.

2. Delete files that start with ‘spec-’ name

Now let’s try to remove specific files from a folder that start with spec- name.

Check the following code to get specific files from a folder by matching a pattern.

We have to follow the same code as written in the first point. Let’s combine all codes together to make it work.

3. Delete all files

At last, we are going to delete all the files from a folder. So for that we will use glob($path.'/*') function to get all the files from a folder and then delete all the files.

Check the following code to delete all files.

delete-all-files.php

4. Example

Let’s combine all above codes together and create an example where we will delete all files from a folder.
