renaming folders only works with chmodd 777

[mindspins]

I'm using the following code in a WordPress functions file to rename a folder in the uploads folder according to the date, but this only works if the chmodd settings of both folders are 777. How can I change this code so I can use at least chmodd 755 to keep my website save.

 

date_default_timezone_set('Europe/Amsterdam'); // set timezone
$foldername = '';
$source = 'uploads';
$allfolders = getDirectory($source); // get folders
$folder = $source.'/'.$allfolders[0]; // get first folder
$month = (int)date('n');
$day = (int)date('j');
$f = 50-$day; $s = 100-$month;
$newfolder = $source.'/'.(string)$f.(string)$s;
if($folder != '' && $folder != $newfolder){
rename($folder, $newfolder);
$foldername = $newfolder."/";
}else if($folder == $newfolder){
$foldername = $newfolder."/";
}
else{ $foldername = 'error';
}

Steps for you:

1. Move everything in the uploads folder someplace else temporarily

2. Delete the uploads folder

3. chmod 077 the folder which contained the uploads folder

 

In a PHP script:

4. Recreate the uploads folder. Keep the default 0755 permissions

5. Move everything back

 

You:

6. chmod 0755 the parent folder

 

This way PHP is the owner of the uploads folder and can do whatever it wants inside of it. Alternatively, if you have root access, you just chown the folder to whatever user PHP/Apache runs as.

I know what you're trying to achieve, but the user is the owner of the folders in use and is triggering the php. That's why I don't understand it?!

Are you sure your PHP scripts are actually running as your user? Normally they are not - it takes a special setup for that to happen.

Well... you've got me doubting here... I might just need to check your solution after I get some sleep... I'll let you know after a good night rest!
