The script you downloaded lists the content of a specified folder  You probably put the unlink - call in one of the while-loops that list the files    EDIT - Now that you posted your code   echo   lt a href    unlink  FileLink     gt  lt img src  images icons delete gif  gt  lt  a gt  lt  td gt      Doing this calls the unlink-function each time the line is written  deleting your file  You have to write a link to a script that contains a delete function and pass some parameter that tells your script what to delete    Example    lt a href   path to script php delete     FileLink     gt delete lt  a gt    You should not pass the path to a file this script and just delete it though  because malevolent being might use it to just delete everything or do other evil things

http   php net manual en function unlink php  Unlink can safely remove a single file  just make sure the file you are removing it actually a file and not a directory      or        if  is file  filepath           unlink  filepath

unlink  path to filename    will delete one file at a time   If your whole files from directory is gone means you listed all files and deleted one by one in a loop   Well you cannot de delete in the same page  You have to do with other page  create a page called deletepage php which will contain script to delete and link to that page with  file  as parameter   foreach  FilesArray as  file         FileLink    Directory      file  FileName         if  OpenFileInNewTab   LinkTarget     target   blank         else  LinkTarget            echo   lt a href     FileLink    gt    FileName   lt  a gt        echo   lt a href  deletepage php file    fileName    gt  lt img src  images icons delete gif  gt  lt  a gt  lt  td gt                On the deletepage php    and also consider to check if the file exists as with the other guy suggested   filename     GET  file      get the filename unlink  DIRNAME  DIRECTORY SEPARATOR  filename     delete it header  location  backto prev      redirect back to the other page   If you don t want to navigate  then use ajax to make elegant

If you want to delete a single file  you must  as you found out  use the unlink   function   That function will delete what you pass it as a parameter   so  it s up to you to pass it the path to the file that it must delete    For example  you ll use something like this    unlink   path to dir filename
