How to delete the specific image in folder using codeigniter?

Question

I am using code-igniter. In my project i would like to delete the specific image in folder(artical_images). If i try to use delete_files() option it deletes all the images in the folder when use the code like,

public function delete_post($value='$id')
    {

        $query=$this->db->query("select artical_profile from articals where artical_id='$value' ");

        $img_name=$query->result()[0]->artical_profile;

        //echo $img_name;

        delete_files('./artical_images/',TRUE);

       // $this->db->where('artical_id',$value);
        //$this->db->delete('articals');

        exit();

    }

But when i include the specific image name taken from db and include with delete file path it doesn't work.The code is below,

public function delete_post($value='$id')
    {

        $query=$this->db->query("select artical_profile from articals where artical_id='$value' ");

        $img_name=$query->result()[0]->artical_profile;

        //echo $img_name;

        delete_files('./artical_images/$img_name',TRUE);

       // $this->db->where('artical_id',$value);
        //$this->db->delete('articals');

        exit();

    }

even i included the realpath option it also not works,

public function delete_post($value='$id')
    {

        $query=$this->db->query("select artical_profile from articals where artical_id='$value' ");

        $img_name=$query->result()[0]->artical_profile;

        $img_name=realpath(APPPATH . '/artical_images/$img_name');

        delete_files('$img_name',TRUE);

        echo $img_name;

       // $this->db->where('artical_id',$value);
        //$this->db->delete('articals');

        exit();

    }

please give some idea to delete the files,

Check if $img_name contains the proper image name or not and if you have the permission to delete the file or not? — Mayank Pandeyz

delete_files uses a directory path to delete all the files in the directory. It applies the recursive unlink command to delete files.

To delete particular file, You can use unlink with the proper file path.

e.g. unlink(FILE_PATH);

Use full path of the file using APPPATH.

unlink('C:/xampp/htdocs/blog_creation/artical_images/artical_images/'.$img_name); i included the full path where the img stored . its not working
