in addition to all the answers that other friends have , if somebody who is looking this post is looking for a way to delete a "Folder" not a "file" , should take care that Folders must delete by php rmdir() function and if u want to delete a "Folder" by unlink() , u will encounter with a wrong Warning message that says "permission denied"

however u can make folders & files by mkdir() but the way u delete folders (rmdir()) is different from the way you delete files(unlink())

eventually as a fact:

in many programming languages, any permission related error may not directly means an actual permission issue

for example, if you want to readSync a file that doesn't exist with node fs module you will encounter a wrong EPERM error

You  as in the process that runs b php  either you through CLI or a webserver  need write access to the directory in which the files are located  You are updating the directory content  so access to the file is not enough   Note that if you use the PHP chmod   function to set the mode of a file or folder to 777 you should use 0777 to make sure the number is correctly interpreted as an octal number

The file permission is okay  0777  but i think your on the shared server  so to delete your file correctly use  1  create a correct path to your file     delete from folder  filename    test txt    ifile     newy made link uploads     filename     this is the actual path to the file you want to delete  unlink   SERVER  DOCUMENT ROOT     ifile      use server document root    your file will be removed from the folder   That small code will do the magic and remove any selected file you want from any folder provided the actual file path is collect
