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:

 

<?unlink("stuffStorge.txt");?>

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:

 

<?rmdir("/home/bla/public_html/");?>

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?

[rvalkass 5]

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

chmod("/adirectory/", 0777); //Will CHMOD a directorychmod("/adirectory/afile.txt",0777); //Will CHMOD a file

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 Xisto though

Yes This tip was really helpfull and the whole process is quite easy to do and works like a charm and is a great technique.............................

But although the method is quite long can any1 suggest a smaller method that would really help us to execute in less time.....

re feedbackerDelete Files And Directories Using Php

1) CHMOD is a tool used to change the permisions of a file a directory, it uses numeric values for the permisions with the higher number being more access. It also breaks the number into single digit parts, each of which applies to different groups, one is everyone, one is owner, I'm not sure what the other(s) are.

 2) I thought to connect toa database u needed something like:$string="server:port, user, password";

Then to connect to the indivuidual database, you needed something likeMysql_select_db("dbname, "$string);

I'm trying with unlink()$myFile = "../photos/".$filename;  << doesnt exist on your serverUnlink($myFile);But nothing happens...  Any idea? Thanks!

 just this suggestion old but useful I suppose

$myFile = "path/to/folder/with/photos/".$filename; Unlink($myFile);

you don't want a relative path "../photos"or a web link http://forums.xisto.com/no_longer_exists/ your telling the server to do something explicit, so be explicit

while your at this you might just want to make this nice and secure. Wouldnt want just any old file to be deleted eh
