How To Delete Files and Directories
follow up from creating them

Hello all and welcome to my second tutorial involving file management. In my previous tutorial, I explained how to create, write and read files. In this tutorial I'll explain how to remove the files and directories you took so long to create. I did not explain last time how to create directories as I did not know, now I do, you can use the mkdir() function.

Now with this tutorial....

Removing Files

Removing files can easily be done with the unlink() function:



The file which you wish to remove must have 0777 chmod permissions aswell as the directory that the file is stored in.

Removing Directories

I have never tried doing this myself but it can be done with the rmdir() function, but I presume like unlink() both the directory you are trying delete and the one that the directory is stored in must have 0777 permissions:



All in all a very simple tutorial explaining this, any questions?

!! The file which you wish to remove must have 0777 chmod permissions !!

the question is how change the permissions with PHP? is possible?

Yes, use this code to change CHMOD values. You must use octal numbers (e.g. always have 4 digits starting with 0).


Hope this helps.

The biggest problem with chmod() is that most of the servers will restrict PHP from using it.

I don't know about Trap17 though
