You can delete the file using   unlink  Your file path     but if you are deleting a file from it s http path then this unlink is not work proper  You have to give a file path correct

Check your permissions first of all on the file  to make sure you can a  see it from your script  and b  are able to delete it   You can also use a path calculated from the directory you re currently running the script in  eg   unlink dirname   FILE              public files      filename      in PHP 5 3 I believe you can use the   DIR   constant instead of dirname   but I ve not used it myself yet

I know this question is a bit old  but this is something simple that works for me very well to delete images off my project I m working on   unlink dirname   FILE        img tasks      image jpg      The dirname   FILE    section prints out the base path to your project  The  img tasks  are two folders down from my base path  And finally  there s my image I want to delete which you can make into anything you need to   With this I have not had any problem getting to my files on my server and deleting them
